Purpose: To determine the prevalence and causes of blindness and vision impairment among people 50 years and older in Nepal., Methods: We conducted seven provincial-level Rapid Assessment of Avoidable Blindness (RAAB) cross-sectional, population-based surveys between 2018-2021. Provincial prevalence estimates were weighted to give nationally representative estimates. Sampling, enumeration, and examination of the population 50 years and older were done at the province level following standard RAAB protocol., Results: Across seven surveys, we enrolled 33,228 individuals, of whom 32,565 were examined (response rate 98%). Females (n = 17,935) made up 55% of the sample. The age-sex-province weighted national prevalence of blindness (better eye presenting visual acuity <3/60) was 1.1% (95% confidence interval [CI] 1.0-1.2%), and any vision impairment <6/12 was 20.7% (95% CI 19.9-21.5%). The prevalence of blindness was higher in women than men (1.3% [95% CI 1.1-1.5%] vs 0.9% [95% CI 0.7-1.0%]). Age-sex weighted blindness prevalence was highest in Lumbini Province (1.8% [95% CI 1.3-2.2%]) and lowest in Bagmati Province (0.7% [95% CI 0.4-0.9%]) and Sudurpaschim Province (0.7% [95% CI 0.4-0.9%]). Cataract (65.2%) was the leading cause of blindness in our sample, followed by corneal opacity (6.4%), glaucoma (5.8%) and age-related macular degeneration (5.3%). Other posterior segment diseases accounted for 8.4% of cases. Cataract was also the leading cause of severe vision impairment (83.9%) and moderate vision impairment (66.8%), while refractive error was the leading cause of mild vision impairment (66.5%)., Conclusion: The prevalence of blindness was higher among women than men and varied by province. The Lumbini and Madesh Provinces in the Terai (plains) region had higher prevalence of blindness than elsewhere. Cataract was the leading cause of blindness, severe vision impairment and moderate vision impairment while refractive error was the leading cause of mild vision impairment., Competing Interests: No authors have competing interests., (Copyright: © 2025 Kumar Mishra et al.

Purpose: Obstructive sleep apnea (OSA) may increase the risk of age-related macular degeneration (AMD) due to repetitive oxygen deprivation or other mechanisms, though whether OSA increases the risk of AMD progression is unknown. The authors analyzed associations between OSA and AMD risk in the Taiwanese population., Methods: The authors identified patients diagnosed with OSA between 2000 and 2018 in the Taiwan National Health Insurance Research Database and used 1:1 propensity score matching on demographics and comorbidities to create a non-OSA cohort. The authors used Cox proportional hazard modeling to investigate the risk of AMD and the risk of progression from nonexudative to exudative AMD in OSA versus non-OSA patients., Results: A total of 66,869 OSA patients were matched with 66,869 non-OSA patients. The hazard ratio of AMD in the OSA cohort was 1.36 (95% confidence interval, 1.29-1.43, P < 0.0001). The hazard ratio for progression from nonexudative to exudative AMD for the OSA cohort was 0.94 (95% confidence interval, 0.77-1.14, P = 0.5073)., Conclusion: Obstructive sleep apnea is associated with a higher risk of developing AMD. However, no increased risk of AMD progression is observed among people with OSA and existing nonexudative AMD.

To assess retinal pigment epithelium (RPE) tears in eyes which underwent pars plana vitrectomy (PPV) for submacular hemorrhage (SMH) secondary to age-related macular degeneration and to investigate the prognostic factors of visual outcomes. This study was a retrospective, observational case series that included 24 eyes of 24 patients who underwent PPV with subretinal tissue plasminogen activator and air for SMH. RPE tears were investigated using spectral-domain or swept-source optical coherence tomography images with raster scan, combined confocal scanning laser ophthalmoscope near-infrared images and color fundus photographs. Multiple regression analysis was performed to identify the predictors of visual outcome at month 3 and 6 after surgery. In 21 eyes out of 24 eyes (87.5%), RPE tear was detected in the posterior pole. Eight eyes (33.3%) had large RPE tears ( ≧ 1 disc diameter (DD)). Out of the 8 eyes, 5 eyes progressed fibrotic scars within 3 months despite successful SMH removal and showed decrease in their visual acuity (VA). The ratio of eyes with large RPE tears ( ≧ 1DD) were significantly higher in eyes which had undergone anti-VEGF therapy within 3 months than in treatment-naïve eyes (71.4% vs. 25.0%, p = 0.048). The multiple regression analysis revealed that a small RPE tear (< 1DD) and treatment-naïve condition were associated with better VA at month 3 and 6. SMH within 3 months after anti-VEGF therapy might be accompanied by a large RPE tear. An RPE tear which was smaller than 1DD and treatment-naïve condition were associated with better prognosis., Competing Interests: Declarations.

Background: The certificate of vision impairment has an important role in enabling access to support for people with vision impairment (VI) and the provision of epidemiological data regarding sight loss. However, the rates of certification may not accurately reflect the number of people living with certifiable VI., Methods: Observational data from a national primary care low vision rehabilitation service between 1 April 2021 and 31 March 2022 were analysed. Descriptive statistics were used to describe the certification status of patients with certifiable VI. For patients with age-related macular degeneration (AMD) and best-corrected visual acuity of 6/60 or worse, logistic regression was undertaken to assess the effects of patient characteristics on certification status., Results: For patients with AMD and certifiable levels of visual acuity, 41.00% (n = 426) were not certified. The reported certification was 60.09% (n = 256) and 58.24% (n = 357) for neovascular AMD and atrophic AMD, respectively. Existing patients of the service were 3.87 times more likely to be certified than new patients (OR 3.87, 95% CI 2.7-5.4). Increasing age (OR 1.02, 95% CI 1.004-1.038) and decreasing visual acuity (OR 0.62, 95% CI 0.50-0.78) were associated with an increased likelihood of certification., Conclusion: A significant number of patients live with certifiable vision impairment but do not access certification. Policy changes in Wales now enable patients with bilateral atrophic AMD to access certification within the primary care setting. Given the unmet need, consideration should be given to primary care certification in the rest of the UK, and in Wales, the potential to expand the scope of conditions., (© 2024 The Author(s).

Purpose: To provide an analysis of structural optical coherence tomography (OCT) and enface infrared reflectance (IR) differences between non-exudative macular neovascularizations (NE MNVs) secondary to age-related macular degeneration (AMD) and NE MNVs secondary to pachychoroid spectrum., Methods: Patients diagnosed with NE-MNV documented by OCTA and dye angiography in the context of either AMD or pachychoroid spectrum were retrospectively included in AMD group and PACHY group respectively. Only treatment-naïve NE MNVs showing persistence of non-exudative status for at least 1 year after diagnosis were considered. Availability of good quality structural OCT B scan and IR enface acquisitions both at baseline and at 1 year follow up was also required., Results: The study population included 15 eyes of 15 patients in AMD group and 13 eyes of 13 patients in PACHY group. AMD group showed at baseline a significantly wider pigment epithelium detachment (PED) apex angle (p = 0.02), higher homogeneity of the PED (p = 0.015), higher PED shadowing(p = 0.03). Both groups experienced a widening of apex angle (flattening of the PED) during follow-up. Ten (76.9%) patients in PACHY group showed a hyporeflective halo at the margins of the PED at baseline compared to 3/15 (20.0%) patients in AMD group (0.007), with no significant changes at 1 year follow up (p = 0.47)., Conclusion: NE-MNVs in pachychoroid eyes are characterized by sharper and more inhomogeneous PEDs with a lighter choroidal shadowing compared to NE-MNVs in AMD eyes. Moreover, they often show a hyporeflective halo around the lesion with IR imaging., Competing Interests: Competing interests: The authors declare no competing interests.

Purpose: Intravitreal injections with anti-vascular endothelial growth factor (VEGF) drugs can slow progression in neovascular age-related macular degeneration (nAMD). Best spectacle-corrected visual acuity (BSCVA) and/or central retinal thickness (CRT) are common barometers of efficacy of this treatment. However, BSCVA does not accurately measure reading ability, which is often severely impacted by nAMD. Since most studies on the effect of intravitreal anti-VEGF injections on reading ability in nAMD have limitations, we conducted an open-label nonrandomized non-blinded self-controlled clinical trial using Radner Charts, a standardized, validated tool for measuring reading ability., Methods: Patients newly diagnosed with active nAMD and scheduled to undergo induction ranibizumab treatment (monthly treatments for 3months) were recruited by convenience sampling in 2010-2013 at a university hospital. The primary outcome was change in Radner Chart-determined reading speed (maximum words/minute [wpm]) at 3months (1month post-third injection) relative to baseline. Secondary outcome measures were 3-month change in BSCVA and CRT. Treatment-induced effects on wpm, BSCVA, and CRT were determined with Wilcoxon tests. Spearman correlations between these variables were evaluated., Results: The injections significantly improved wpm (48 to 75), BSCVA (+9 letters), and CRT (357 to 224μm) (all P<0.0001). BSCVA, but not CRT, correlated with wpm at baseline and 3months (P=0.0004 and 0.03, respectively). BSCVA and CRT were not correlated, unless change in these variables was considered, possibly because of a non-linear relationship., Conclusion: Anti-VEGF treatment significantly improved reading ability. Whether BSCVA can serve as a clinically meaningful assessment of reading ability requires further research. Baseline variables may not help to identify patients with poor reading speed responses to treatment., (Copyright © 2024 The Author(s). Published by Elsevier Masson SAS.. All rights reserved.)

Purpose: To describe novel microperimetry and imaging findings in two patients affected by extensive macular atrophy with pseudodrusen-like appearance without signs of retinal pigment epithelium atrophy., Methods: Case series. Both patients underwent mesopic and dark-adapted two-color scotopic microperimetry, followed by multimodal imaging assessment including ultra-widefield photography, fundus autofluorescence, high-resolution optical coherence tomography, optical coherence tomography angiography, and high-magnification module., Results: Albeit normal visual acuity, both patients had a significant reduction of retinal sensitivity-especially under scotopic cyan conditions. One patient had macular pigment abnormalities, whereas the combination of blue and near-infrared autofluorescence modalities highlighted different patterns of pseudodrusen-like lesions.Of notice, high-resolution optical coherence tomography revealed a marked separation between the retinal pigment epithelium and Bruch membrane, containing a hyperreflective material with two different reflectivities. Optical coherence tomography angiography excluded the presence of macular neovascularization and documented several choriocapillaris flow voids. High-magnification module images showed severe alteration of photoreceptors' mosaic in the perifovea., Conclusion: Our comprehensive assessment of two stage 1 extensive macular atrophy with pseudodrusen-like appearance patients revealed a predominant damage of perifoveal rods over areas of retinal pigment epithelium-Bruch membrane separation. These findings underscore the importance of basal laminar deposits in the initial stages of extensive macular atrophy with pseudodrusen-like appearance, contributing to a deeper understanding of its underlying mechanisms.

Extensive macular atrophy with pseudodrusen-like appearance (EMAP) was first described in France in 2009 as a symmetric and rapidly progressive form of macular atrophy primarily affecting middle-aged individuals. Despite the recent identification of a significant number of cases in Italy and worldwide, EMAP remains an underrecognized condition. The clinical triad typical of EMAP consists of vertically oriented macular atrophy with multilobular borders, pseudodrusen-like deposits across the posterior pole and mid-periphery, and peripheral pavingstone degeneration. Nonetheless, recent research has portrayed EMAP as a highly stage-dependent condition, allowing the identification of novel disease hallmarks, including a diffuse separation between the Bruch's membrane and the retinal pigment epithelium, along with consistent sparing of a region temporal to the macula. Additionally, retinal electrophysiology is particularly useful in distinguishing EMAP from age-related macular degeneration (AMD). Supported by unpublished data from the largest EMAP cohorts worldwide, this review aims to provide a comprehensive and updated description of EMAP, now recognized as a severely blinding disease characterized by diffuse chorioretinal atrophy and photoreceptor dysfunction. Furthermore, we propose a set of diagnostic criteria that incorporate clinical, imaging, and functional tests, to facilitate the recognition of this clinical entity. Lastly, we aim to shed light on its pathogenesis by comparing it with AMD and monogenic retinal disorders exhibiting similar phenotypes., (Copyright © 2024 The Authors. Published by Elsevier Ltd..

Background: Age-related macular degeneration (AMD) is a leading cause of blindness and low vision worldwide. This study examines the global burden and trends in AMD-related low vision and blindness from 1990 to 2021, with projections through 2050., Methods: Data were obtained from the 2021 Global Burden of Disease (GBD 2021) study, covering 204 countries and regions. Key metrics, including the prevalent case numbers, annual disability-adjusted life years (DALYs), age-standardized prevalence rates (ASPR), and age-standardized DALY rates (ASDALYR), specific to low vision and blindness due to AMD, were calculated per 100,000 population. Trend analysis used the estimated annual percentage change (EAPC) method, and K-means clustering identified regions with similar burdens and trends. Autoregressive Integrated Moving Average(ARIMA) and Exponential Smoothing(ES) models provided future projections., Results: Globally, the total number of prevalent cases and DALYs has substantially increased. The number of prevalent cases of low vision and blindness due to AMD increased from 3,640,180 (95% UI: 3,037,098 - 4,353,902) in 1990 to 8,057,521 (95% UI: 6,705,284-9,823,238) in 2021. DALYs increased from 302,902 (95% UI: 206,475 - 421,952) in 1990 to 578,020 (95% UI: 401,241-797,570) in 2021. From 1990 to 2021, both the ASPR and ASDALYR for AMD-related low vision and blindness showed a downward trend. The ASPR was 94 (95% UI: 78.32-114.42) per 100,000 population, with an EAPC of -0.26 (95% CI: -0.31 to -0.22), and the ASDALYR was 6.78 (95% UI: 4.7-9.32) per 100,000 population, with an EAPC of -0.94 (95% CI: -1.01 to -0.88). The disease burden of AMD-related low vision and blindness increases with age, and the burden for female patients is slightly higher than for males. Regional stratification by the Socio-Demographic Index (SDI) shows that the burden of AMD-related low vision and blindness in areas with low SDI is higher than in areas with high SDI. From 1990 to 2021, notable increases in ASPR and ASDALYR were observed mainly in the southern and central regions of sub-Saharan Africa. Moreover, the increases in prevalence and DALYs vary by region, country, and level of socioeconomic development. The ARIMA model predicts that by 2050, the number of prevalent cases of low vision and blindness due to AMD will reach 13,880,610(95% CI: 9,805,575-17,955,645), and the DALYs will be 764,731(95% CI: 683,535-845,926). The ES model predicts that by 2050, the number of prevalent cases of AMD-related low vision and blindness will reach 9,323,124(95% CI: 5,222,474-13,423,774), and the DALYs will be 641,451 (95% CI: 383,588-899,318)., Conclusion: This study indicates that between 1990 and 2021, the global prevalent cases and DALYs caused by AMD-related low vision and blindness have increased over the past three decades, correlating with factors such as age, gender, socioeconomic status, and geographical location. Predictive models indicate that as the population ages, the number of patients with low vision and blindness due to AMD, along with associated DALYs, will continue to rise. By 2050, it is expected that over 9 million people worldwide will be affected by AMD-related vision loss, with women being particularly impacted. These findings can provide data support for public health planning, resource allocation, and the formulation of medical policies, ensuring an effective response to the challenges posed by the future increase in AMD-related low vision and blindness., Competing Interests: Declarations.

Objective: To analyze the presence and morphologic characteristics of drusenoid pigment epithelial detachments (DPEDs) in spectral-domain optical coherence tomography (SD-OCT) in Caucasian patients with early and intermediate age-related macular degeneration (AMD) as well as the influence of these characteristics on best-corrected visual acuity (BCVA) and disease progression., Design: Prospective observational cohort study., Participants: 89 eyes of 56 patients with early and intermediate AMD., Methods: Examinations consisted of BCVA, SD-OCT, and indocyanine green angiography. Evaluated parameters included drusen type, mean drusen height and -volume, the presence of DPED, DPED maximum height, -maximum diameter, -volume, topographic location, the rate of DPED collapse, and the development of macular neovascularization (MNV) or geographic atrophy (GA)., Results: DPED maximum height (162.34 µm ± 75.70 μm, p = 0.019) was significantly associated with the development of GA and MNV. For each additional 100 μm in maximum height, the odds of developing any late AMD (GA or MNV) increased by 2.23 (95% CI = 1.14-4.35). The presence of DPED (44 eyes, p = 0.01), its volume (0.20 mm ± 0.20 mm, p = 0.01), maximum diameter (1860.87 μm ± 880.74 μm, p = 0.03), maximum height (p < 0.001) and topographical location in the central millimetre (p = 0.004) of the Early Treatment Diabetic Retinopathy Study (ETDRS)-Grid were significantly correlated with BCVA at the last follow-up (0.15logMAR ± 0.20logMAR; Snellen equivalent approximately 20/28). DPEDs occurred significantly less in the outer quadrants than in the central millimetre and inner quadrants of ETDRS-Grid (all p values < 0.001)., Conclusions: The height of drusen and DPEDs is a biomarker that is significantly associated with the development of late AMD and visual loss. DPEDs affect predominantly the center and inner quadrants of the ETDRS-Grid., Competing Interests: Footnotes and Disclosure G.S.R. has received grant funding from RetInSight and speaker fees from Apellis.

Background: Nocturnal hypoxia is common, under-diagnosed and is found in the same demographic at risk of age-related macular degeneration (AMD). The objective of this study was to determine any association between nocturnal hypoxia and AMD, its severity, and the high-risk sub-phenotype of reticular pseudodrusen (RPD)., Methods: This cross-sectional study included participants aged ≥50 years with AMD, or normal controls, exclusive of those on treatment for obstructive sleep apnoea. All participants had at home, overnight (up to 3 nights) pulse oximetry recordings and multimodal imaging to classify AMD. Classification of Obstructive Sleep Apnea (OSA) was determined based on oxygen desaturation index [ODI] with mild having values of 5-15 and moderate-to-severe >15., Results: A total of 225 participants were included with 76% having AMD, of which 42% had coexistent RPD. Of the AMD participants, 53% had early/intermediate AMD, 30% had geographic atrophy (GA) and 17% had neovascular AMD (nAMD). Overall, mild or moderate-to-severe OSAwas not associated with an increased odds of having AMD nor AMD with RPD (p ≥ 0.180). However, moderate-to-severe OSA was associated with increased odds of having nAMD (odds ratio = 6.35; 95% confidence interval = 1.18 to 34.28; p = 0.032), but not early/intermediate AMD or GA, compared to controls (p ≥ 0.130). Mild OSA was not associated with differences in odds of having AMD of any severity (p ≥ 0.277)., Conclusions: There was an association between nocturnal hypoxia as measured by the ODI and nAMD. Hence, nocturnal hypoxia may be an under-appreciated important modifiable risk factor for nAMD., (© 2024 The Author(s).

Background/aims: Demonstrate through objective multidisciplinary imaging that subretinal drusenoid deposits (SDDs) in age-related macular degeneration (AMD) are linked to both coexistent valvular heart disease (VHD) and reduced systemic perfusion via cardiac index (CI)., Methods: Post-hoc analysis of cross-sectional study. 200 intermediate AMD (iAMD) subjects were assigned by masked readers to two groups: SDD (with or without drusen) and drusen (only) based on multimodal ophthalmic imaging. 65 transthoracic echocardiograms (TTEs) reports were available for cardiologist evaluation of VHD severity of the four cardiac valves and the presences of precursor lesions of aortic sclerosis (ASc) and mitral annular calcification (MAC). Necessary parameters to calculate CI were also obtained. Univariate testing was performed using Fisher's Exact test and t-test., Results: 82.6% (19/23) of the iAMD subjects with at least one moderate/severe VHD had concurrent SDDs ( p  = 0.0040). All cases of aortic regurgitation (6/6, p  = 0.0370) and mitral regurgitation (13/13, p  = 0.0004) were found with coexisting SDDs. Stenotic VHD was not significantly associated with SDDs, however 70.7% of subjects with ASc (29/41, p  = 0.0108) and 76.0% of subjects with MAC (19/25, 0.0377) had coexisting SDDs. CI was available in 48 subjects and was significantly below normal levels in the SDD cohort (mean CI SDD 1.95 ± 0.60 L/min/m 2 , non-SDD 2.71 ± 0.73 L/min/m 2 , p  = 0.0004)., Conclusions: Several specific VHDs have been found associated with the SDD form of AMD. Decreased systemic perfusion as measured by CI was also associated with SDDs, which supports a perfusion hypothesis of SDD pathogenesis. Further research is warranted to understand the relationship between cardiovascular disease and SDDs., Competing Interests: Declaration of conflicting interestsThe authors declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: RBR is a consultant to OptoVue, Boehringer-Ingelheim, Astellas, Genentech-Roche, NanoRetina, OD-OS, Regeneron, Bayer, Diopsys, and Teva.

The presence of subretinal drusenoid deposits (SDDs) in patients with age-related macular degeneration (AMD) appears to be correlated with cardiovascular disease (CVD) and may serve as a useful tool for predicting certain forms of CVD. Here, we tested this hypothesis by examining whether patients with AMD with SDDs are more likely to have a cardiovascular-related condition and/or undergo a cardiovascular procedure. This is a retrospective cohort study. We included a total of 597 patients with AMD either with SDDs (n = 332) or without SDDs (n = 265). All patients underwent spectral-domain optical coherence tomography (SD-OCT). The SD-OCT scans were annotated by masked, experienced graders. We also extracted data from the patients' electronic medical records (EMRs), including patient demographics, cardiovascular diagnoses, and CVD-related procedures based on ICD-9 codes. AMD patients with SDDs were more likely to be diagnosed with CVD or undergo a cardiovascular procedure compared to AMD patients without SDDs, particularly percutaneous transluminal coronary angioplasty (PTCA; OR 2.73, 95% CI [1.21, 6.13], p = 0.02). Multivariate analysis confirmed the association between the presence of SDDs and a background of PTCA in the presence of other covariates. These data suggest that the presence of SDDs in patients with AMD correlates with certain severe cardiovascular conditions; SDDs and CVD may share common pathogenic pathways., (© 2024.

Background: Cataract, glaucoma and age-related macular degeneration (AMD) are major causes of visual impairment. As these are age-related conditions, the prevalence of associated visual impairment is anticipated to increase as the population ages. However, age-period-cohort effects on the disease burden have not been investigated., Methods: This was a population-based study using aggregated data from the Global Burden of Disease Study 2019. Age-period-cohort analysis was conducted using age-standardised prevalence rates (ASPRs) of visual impairment caused by cataract, glaucoma and AMD as disease burden indicator., Results: In 2019, the estimated global ASPRs of visual impairment due to cataract, glaucoma and AMD were 1207.9, 94.7 and 96.8 per 100 000 people, respectively. Between 1990 and 2019, the global visual impairment ASPRs for glaucoma and AMD declined by 15.4% and 2.0%, respectively, whereas that for cataract increased by 5.0%. Wide heterogeneity was observed in age-period-cohort effects on ASPRs across different Sociodemographic Index (SDI) regions. Low-middle SDI regions had the largest ASPR reductions for all three eye diseases and showed improvement in both period and cohort effects. In contrast, in high-middle SDI regions, visual impairment ASPRs significantly increased during the study period with unfavourable patterns., Conclusions: The wide heterogeneity in age-period-cohort effects reflects different stages of societal transition and vision health. The unfavourable trends in age-period-cohort effects on disease prevalence identified in specific groups provide key information that may be used to identify priority groups in need of treatment and prevention., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Objective: To use ultra-widefield swept-source optical coherence tomography angiography (UWF SS-OCTA) to evaluate the choroidal features of neovascular age-related macular degeneration (nAMD) and type 1 macular neovascularization (MNV) attributable to central serous chorioretinopathy (CSC)., Method: A cross-sectional research was carried out to examine patients with type 1 MNV due to CSC (50 eyes) and nAMD (98 eyes) utilizing UWF SS-OCTA examinations. The scan procedure covered a vertical 20 mm × horizontal 24 mm region with 9 subfields. A typical set of 68 healthy eyes was used for comparison. The effects of different diagnoses on choroidal parameters were assessed using covariance tests, using gender and age as variables., Results: The research showed that all choroidal characteristics were age-related (all p < 0.05). The calculated marginal averages of choroidal thickness (ChT) and choroidal volume (CV) in the central area were substantially lower in the nAMD group than in the CSC group and the normal group after age differences were taken into account (all p < 0.05). In both the superotemporal and temporal areas, the CSC group had a greater choroidal vascular index (CVI) compared to the nAMD group (p < 0.05). Additionally, the CSC group had a greater temporal area choriocapillaris density (CCD) than the nAMD group (p < 0.05)., Conclusion: At the choroidal level, type 1 MNV due to CSC and nAMD may be distinguished by UWF SS-OCTA. Compared to the nAMD affected eyes, the CSC affected eyes had increased ChT, CV, CVI, and CCD in several areas. The two diseases could be distinguished based on ChT and CV., Competing Interests: Declaration of competing interest The authors declare that they have no competing interests., (Copyright © 2024.

Purpose: This review focuses on extensive macular atrophy with pseudodrusen-like appearance (EMAP), a recently described maculopathy presenting with pseudodrusen-like lesions and chorioretinal atrophy more pronounced in the vertical axis., Methods: Narrative review of the literature published until May 2024., Results: The early onset age of EMAP (50-55 years) and its distinctive natural history, which includes night blindness followed by severe vision loss, differentiate it from atrophic age-related macular degeneration (AMD). A clear pathogenesis has not been determined, but risk factors include female gender and complement system abnormalities (altered levels of C3 and CH50). Moreover, lifelong exposure to pesticides has been suggested as risk factor for direct neuronal degeneration involving rods and cones. In the early phase of the disease, reticular pseudodrusen-like lesions appear in the superior perifovea and tend to coalescence horizontally into a flat, continuous, reflective material localized between the retinal pigmented epithelium and Bruch's membrane. Over time, EMAP causes profound RPE and outer retinal atrophy in the macular area, with a recent classification reporting a 3-stages evolution pattern. Blue autofluorescence showed rapidly evolving atrophy with either hyperautofluorescent or isoautofluorescent borders. Significant similarities between the diffuse-trickling phenotype of geographic atrophy and EMAP have been reported. Macular neovascularization is a possible complication., Conclusion: EMAP is specific form of early-onset atrophic macular degeneration with rapid evolution and no treatment. Further studies are needed to assess the best management., (© 2024. The Author(s).)

Background and Objective: Age-related macular degeneration (AMD) and diabetic retinopathy (DR) are highly prevalent., Objective: To explore perceptions of patients with AMD or DR about the impact of the disease and treatment on their daily living activities., Materials and Methods: Semi-structured interviews with a questionnaire developed from validated patient reported outcomes questionnaires. The questionnaire consisted of 19 questions about the disease and 9 about the treatment. The questions (items) were answered on a scale from 1 to 9. In addition, the patient interviewed was invited to make free comments on each question. Nine patients with AMD and 9 with DR were interviewed by videoconference or telephone call. A quantitative analysis of the responses and a qualitative analysis of the comments were carried out., Results: The most relevant item for patients with AMD or DR is "Recognize people when they are nearby", and "Read text in normal size font in a newspaper or book", followed, in patients with AMD, by "Do things what you would like" and, in patients with DR, "Feeling frustrated by the vision problems." Regarding the treatment, the most relevant aspects for both groups is that the treatment works and receiving appropriate information before and after the treatment. The qualitative comments were focused to the disease, the treatment, and to the role of doctors and the health system., Conclusion: Quantitative responses and free comments can be useful to improve the care of patients with AMD or DR by physicians and the health system., (Copyright © 2024 Sociedad Española de Oftalmología.

Purpose: To characterize and quantify the precursor lesions of geographic atrophy in eyes with age-related macular degeneration., Methods: A retrospective study of eyes with a minimum of 6-month follow-up before developing geographic atrophy. Evaluations included color and autofluorescence imaging, along with spectral-domain optical coherence tomography, employing definitions from the Consensus of Atrophy Meeting Group and Consensus on Neovascular Age-Related Macular Degeneration Nomenclature Study Group., Results: There were 55 eyes of 44 patients, who had a mean age of 81.3 years at onset of atrophy; 35 (63.6%) were female. The mean duration of follow-up before and after the advent of geographic atrophy was 4.9 years and 1.2 years, respectively. Geographic atrophy was preceded by collapse of a druse in 41 eyes (74.5%). Of these, 29 (70.7%) were drusenoid pigment epithelial detachments. Among the eyes with regressing drusen, there were 9 with overlying vitelliform deposit, and all had concurrent subretinal drusenoid deposit; however, 19 of 30 eyes with no vitelliform deposit overlying the druse had concurrent subretinal drusenoid deposit, a difference that was significant ( P < 0.001). Regression of subretinal drusenoid deposit was found in 4 eyes (7.3%), regression of vitelliform deposit associated with subretinal drusenoid deposit in 5 (9.1%), and regression of vitelliform deposit in eyes concurrently harboring drusen was found in 3 (5.4%) and regression of vitelliform deposit alone in 2 (3.6%) at the site of eventual development of geographic atrophy., Conclusion: Geographic atrophy appears to develop from multiple pathways as manifested by the many precursor lesions, all various forms of extracellular deposit, that upon regression, result in a common end-stage appearance.

Previous studies on the association between age-related macular degeneration (AMD) and rheumatoid arthritis (RA) have shown conflicting results. We sought to assess the association between AMD with/without visual disability (VD) and the risk of RA using National Health Insurance data in South Korea. In total, 3,537,293 individuals who underwent health checkups in 2009 were included and followed until 2019. Participants with VD were defined as those with loss of vision or a visual field defect as certified by the Ministry of Health and Welfare of Korea. Using multivariable adjusted Cox regression analysis, RA hazard ratios were estimated for control and AMD with/without VD groups. In total, 43,772 participants (1.24%) were diagnosed with RA. Individuals with AMD were at higher risk of RA compared to controls, regardless of the presence of VD (aHR 1.11; 95% CI 1.02-1.21). Among individuals with AMD, different risk levels of RA were observed between those without VD (aHR 1.13; 95% CI 1.03-1.21) and those with VD (aHR 0.90; 95% CI 0.64-1.27). AMD was associated with a higher risk of RA, which remained significant as a trend even after adjusting for lifestyle factors and comorbidities., (© 2024. The Author(s).)

To our knowledge, this is the first report of a patient with both genetically confirmed Kabuki and Marfan syndrome demonstrating a perifoveal macular degeneration in one eye. Progressive loss of the outer retinal layers was captured and demonstrated with spectral-domain optical coherence tomography imaging. Fundus autofluorescence imaging revealed perifoveal hypoautofluorescence. The patient had initially presented with a spontaneously resolved serous-exudative retinal detachment associated with tortuous retinal vasculature and preretinal proliferative vitreoretinopathy in the other eye. Prior to presentation, the patient had an ocular history of bilateral ectopia lentis treated with crystalline lens removal and placement of iris-claw intraocular lenses.

Age-related macular degeneration (AMD) is a leading cause of blindness. It is associated with peripheral drusen which has not been categorized. We investigated peripheral drusen to validate an image grading system and to understand possible associations between peripheral drusen and AMD. We collated clinical data, ultra-widefield (UWF) pseudocolor fundus images and Spectral-Domain Optical Coherence Tomography (SD-OCT) scans from consecutive retinal patients. SD-OCT scans were used to determine AMD stage. A masked retinal specialist recorded the types of peripheral drusen observed in UWF images. Eyes whose UWF images did not pass quality screening and those without AMD and peripheral drusen were excluded from the study. Statistical tests were utilized to determine the validity of our grading system and associations of peripheral drusen with AMD. A total of 481 eyes (283 subjects) were included in the study (mean age 73.1 ± 1.2years, 64.3% female). Interobserver and test-retest statistical analyses to evaluate the UWF image grading system resulted in Cohen's Kappa 0.649 (p < 0.001) and 0.922 (p < 0.001) respectively. A total of 284 (59.0%), 28 (5.8%), 15 (3.1%), 22 (4.6%), 4 (0.8%), 39 (8.1%), and 32 (6.7%) eyes had hard, soft, reticular, cuticular, atrophic, mixed drusen, and mixed drusen and atrophy respectively in at least one peripheral retinal quadrant. Hard peripheral drusen was significantly associated with the presence of AMD (p = 0.010). Peripheral drusen types were variably seen in retinal patients with and without AMD. We validated a peripheral drusen grading system and provided an image library to assist in the identification of peripheral drusen. Our study found an association between peripheral hard drusen and an AMD diagnosis but did not find a link between peripheral drusen and severity of AMD., (© 2024. The Author(s).)

Aims: The aim of this study is to assess baseline characteristics of drusen preceding the development of intraretinal hyper-reflective foci (IHRF) in eyes with intermediate age-related macular degeneration (AMD)., Methods: In this retrospective case-control study, longitudinal optical coherence tomography (OCT) volume data from eyes with intermediate AMD in a retina clinic population were screened. All drusen that developed overlying IHRF were marked. A random number generator was used to select for further grading three drusen that did not develop IHRF., Results: Ninety eyes (from 72 patients), including 140 drusen with overlying IHRF and 270 IHRF- drusen, were analysed. Greater drusen height, basal drusen width and overlying ellipsoid zone (EZ) and external limiting membrane disruption were associated with a significantly greater risk for IHRF development (p≤0.001). Regression analysis revealed EZ disruption increased these odds by 4.1 (p≤0.001). Each 10-µm increase in drusen height and width increased the odds by 34% (p≤0.001) and 3% (p: 0.005), respectively. Each 100-µm increase in distance from the fovea decreased the odds by 10% (p: 0.013)., Conclusions: The presence of overlying EZ disruption and a greater drusen height substantially increased the risk for IHRF development, whereas drusen further from the fovea indicated reduced risk. Given the importance of IHRF as a biomarker for AMD progression, these findings may be of value in defining patient populations for future early intervention trials., Competing Interests: Competing interests: SriniVas R.

Purpose: To determine the relationship between structural biomarkers on OCT that increase the risk of disease progression and microperimetric retinal sensitivity in patients with intermediate age-related macular degeneration (iAMD)., Design: Prospective cross-sectional, observational study., Participants: Forty-five eyes of 23 patients with iAMD., Methods: Patients underwent OCT and microperimetry. OCT scans were evaluated for the risk factors intraretinal hyperreflective foci (HRF), hyporeflectivity within drusenoid lesions (HRDL), subretinal drusenoid deposits, double-layer sign (DLS), and drusen volume. Microperimetric retinal sensitivity was analyzed with a 33-point grid covering the macula. With a novel method of determining what part of the retina corresponded to each microperimetry point, a Voronoi diagram was constructed, dividing the macula in cells consisting of the region nearer to each point than any other. The Voronoi diagram was superimposed on the OCT, making it possible to determine the point-to-point location of the OCT risk factors. Univariable and multivariable linear mixed-effect models were used for analysis., Main Outcome Measures: Association between microperimetric retinal sensitivity and OCT risk factors at individual measuring points., Results: One thousand four hundred seventy-nine points of retinal sensitivity and corresponding structural area on OCT were included in this study. Retinal sensitivity was significantly decreased with presence of the OCT risk factors HRF, HRDL, DLS, and drusen volume (all P < 0.001) when analyzed with the univariable linear mixed-effect model. The multivariable model showed a significant decrease of retinal sensitivity with presence of HRF (P < 0.001), DLS (P = 0.025), and greater drusen volume (P < 0.001)., Conclusions: Presence of HRF, DLS, and greater drusen volume, all of which increase the risk of disease progression, is significantly and independently associated with decreased microperimetric retinal sensitivity in patients with iAMD., Financial Disclosure(s): Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (Copyright © 2024 American Academy of Ophthalmology.

Purpose: The pathogenesis of age-related macular degeneration (AMD) involves aberrant complement activation and is a leading cause of vision loss worldwide. Complement aberrations are also implicated in many systemic immune-mediated inflammatory diseases (IMIDs), but the relationship between AMD and these conditions remains undescribed. The aim of this study is to first assess the association between AMD and IMIDs, and then assess the risk of AMD in patients with specific IMIDs associated with AMD., Design: Cross-sectional study and cohort study., Subjects and Controls: Patients with AMD were compared with control patients with cataracts and no AMD to ensure evaluation by an ophthalmologist. Patients with IMIDs were compared with patients without IMIDs but with cataracts., Methods: This study used deidentified data from a national database (2006-2023), using International Classification of Diseases 10 codes to select for IMIDs. Propensity score matching was based on patients on age, sex, race, ethnicity, and smoking. Odds ratios were generated for IMIDs and compared between AMD and control patients. For IMIDs associated with AMD, the risk of AMD in patients with the IMID versus patients without IMIDs was determined utilizing a cohort study design., Main Outcome Measures: Odds ratio of IMID, risk ratios (RRs), and 95% confidence intervals (CIs) of AMD diagnosis, given an IMID., Results: After propensity score matching, AMD and control cohorts (n = 217 197 each) had a mean ± standard deviation age of 74.7 ± 10.4 years, were 56% female, and 9% of patients smoked. Age-related macular degeneration showed associations with systemic lupus erythematosus (SLE), Crohn's disease, ulcerative colitis, rheumatoid arthritis (RA), psoriasis, sarcoidosis, scleroderma, giant cell arteritis, and vasculitis. Cohorts for each positively associated IMID were created and matched to control cohorts with no IMID history. Patients with RA (RR, 1.40; 95% CI, 1.30-1.49), SLE (RR, 1.73; 95% CI, 1.37-2.18), Crohn's disease (RR, 1.42; 95% CI, 1.20-1.71), ulcerative colitis (RR, 1.45; 95% CI, 1.29-1.63), psoriasis (RR, 1.48; 95% CI, 1.37-1.60), vasculitis (RR, 1.48; 95% CI, 1.33-1.64), scleroderma (RR, 1.65; 95% CI, 1.35-2.02), and sarcoidosis (RR, 1.42; 95% CI, 1.24-1.62) showed a higher risk of developing AMD compared with controls., Conclusions: The results suggest that there is an increased risk of developing AMD in patients with RA, SLE, Crohn's disease, ulcerative colitis, psoriasis, vasculitis, scleroderma, and sarcoidosis compared with patients with no IMIDs., Financial Disclosure(s): Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (Copyright © 2024 American Academy of Ophthalmology.

Introduction: SB11 (Byooviz™; Samsung Bioepis Co., Ltd.) is a ranibizumab (Lucentis ® ; Genentech, Inc.) biosimilar targeting vascular endothelial growth factor A for the treatment of retinal diseases. The pre-filled syringe (PFS) presentation of SB11 offers an alternative administration method to the vial, with the potential for enhanced safety and efficient syringe preparation. The objective of this study was to assess the ability of healthcare professionals (HCPs) to follow the instructions for use to prepare and administer SB11 PFS intravitreal (IVT) injections to patients with neovascular age-related macular degeneration (nAMD) or macular edema secondary to retinal vein occlusion (RVO)., Methods: This study was an open-label, single-arm, single-dose clinical study to evaluate the usability of the SB11 PFS in patients with nAMD or macular edema secondary to RVO. Four HCPs prepared and administered 0.5 mg SB11 PFS IVT injections to 34 patients. Product use task completion (12 tasks in total) was assessed by independent observers. Safety was assessed up to 7 days after injection of the investigational product., Results: A total of 34 patients were enrolled and completed the study. All 12 tasks were successfully completed in 34 (100%) patients without a use-related failure. Most patients (32 patients, 94.1%) experienced no adverse events (AEs), whereas 2 (5.9%) patients experienced three treatment-emergent AEs (TEAEs) which were mild to moderate in severity. There were no severe or serious TEAEs reported during the study., Conclusions: This study showed that HCPs were able to successfully prepare and administer the SB11 PFS via IVT injection. No unexpected safety issues were identified. The SB11 PFS is a promising alternative for therapeutic administration of SB11 in patients with retinal disease., Trial Registration: ClinicalTrials.gov identifier NCT06176963; EudraCT number 2021-003566-12., (© 2024.

Background: We aimed to update estimates of global vision loss due to age-related macular degeneration (AMD)., Methods: We did a systematic review and meta-analysis of population-based surveys of eye diseases from January, 1980, to October, 2018. We fitted hierarchical models to estimate the prevalence of moderate and severe vision impairment (MSVI; presenting visual acuity from <6/18 to 3/60) and blindness ( < 3/60) caused by AMD, stratified by age, region, and year., Results: In 2020, 1.85 million (95%UI: 1.35 to 2.43 million) people were estimated to be blind due to AMD, and another 6.23 million (95%UI: 5.04 to 7.58) with MSVI globally. High-income countries had the highest number of individuals with AMD-related blindness (0.60 million people; 0.46 to 0.77). The crude prevalence of AMD-related blindness in 2020 (among those aged ≥ 50 years) was 0.10% (0.07 to 0.12) globally, and the region with the highest prevalence of AMD-related blindness was North Africa/Middle East (0.22%; 0.16 to 0.30). Age-standardized prevalence (using the GBD 2019 data) of AMD-related MSVI in people aged ≥ 50 years in 2020 was 0.34% (0.27 to 0.41) globally, and the region with the highest prevalence of AMD-related MSVI was also North Africa/Middle East (0.55%; 0.44 to 0.68). From 2000 to 2020, the estimated crude prevalence of AMD-related blindness decreased globally by 19.29%, while the prevalence of MSVI increased by 10.08%., Conclusions: The estimated increase in the number of individuals with AMD-related blindness and MSVI globally urges the creation of novel treatment modalities and the expansion of rehabilitation services., (© 2024.

Objective: The primary goal of this study was to determine how structural and functional parameters influence the vision-related quality of life (VRQoL) in patients suffering from geographic atrophy (GA) secondary to age-related macular degeneration., Design: This study was designed as a prospective, noninterventional, natural-history study (Directional Spread in Geographic-Atrophy study, NCT02051998)., Subjects: The research involved 82 patients with bilateral GA., Methods: The study examined parameters including GA location as assessed by the ETDRS grid, best-corrected visual acuity, low-luminance visual acuity (LLVA), reading acuity, and speed. These parameters were then correlated with VRQoL, which was gauged using the National Eye Institute Visual Function Questionnaire 25. The analysis method employed was the least absolute shrinkage and selection operator with linear mixed-effects models., Main Outcome Measures: The central parameters measured in this study encompassed GA area, VRQoL scores associated with different GA subfields, and the significance of LLVA for foveal-sparing patients., Results: On average, patients showed a total GA area of 2.9 ± 1.2 mm 2 in the better eye (BE) and 3.1 ± 1.3 mm 2 in the worse eye. The most significant associations with VRQoL scores for distance and near activities were observed in the inner lower and inner left subfields of the BE, respectively. For patients with foveal-sparing GA, the LLVA of the BE stood out as the most influential variable across all VRQoL scales., Conclusions: The study's findings point toward the pivotal role of GA location, especially the inner lower and inner left subfields of the BE, in relation to VRQoL in GA patients. The LLVA's importance becomes even more pronounced for foveal-sparing patients. These observations highlight the need for health care professionals to better understand the association between lesion location and patient-reported outcomes. This is critical for informing treatment decisions and refining the planning of interventional trials., Financial Disclosure(s): Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (Copyright © 2024 American Academy of Ophthalmology.

Background and Objectives : In this study, our objective was to assess and compare the changes in visual and structural outcomes among patients with neovascular age-related macular degeneration (nAMD) who were switched from intravitreal aflibercept (IVA) to either intravitreal brolucizumab (IVBr) or intravitreal faricimab (IVF) injections in a clinical setting. Materials and Methods : This observational clinical study included 20 eyes of 20 patients switched to brolucizumab and 15 eyes of 14 patients switched to faricimab from aflibercept in eyes with nAMD. We measured the structural outcome (central macular thickness (CMT)) and the visual outcome (best-corrected visual acuity (BCVA); logMAR) as follows: just before the most recent IVA injection (B0), one month after the most recent IVA injection (B1), just before the first IVBr or IVF injection (A0), one month after (A1) and three months after (A3) the first IVBr or IVF injection. Results : BCVA showed significant improvement at A1 (0.25 ± 0.34) and at A3 (0.19 ± 0.24) compared to A0 (0.38 ± 0.35) in the IVBr group ( p = 0.0156, p = 0.0166, respectively). CMT (μm) was significantly thinner at A1 (IVBr: 240.55 ± 51.82, IVF: 234.91 ± 47.29) and at A3 (IVBr: 243.21 ± 76.15, IVF: 250.50 ± 72.61) compared to at A0 (IVBr: 303.55 ± 79.18, IVF: 270.33 ± 77.62) in the IVBr group (A1: p = 0.0093, A3: p = 0.0026) and in the IVF group (A1: p = 0.0161, A3: p = 0.0093). There was no significant difference in BCVA and CMT improvement observed between two groups at any time point ( p > 0.05 for all). Conclusions : Switching from aflibercept to either brolucizumab or faricimab has a significant anatomical effect in eyes with nAMD and both treatments appear to be effective short-term treatment options. There is a trend towards greater visual improvements and reductions in CMT with brolucizumab.

Background/aims: We sought to evaluate widefield swept-source optical coherence tomography angiography (WF SS-OCTA) among eyes with concomitant age-related macular degeneration (AMD) and diabetes mellitus or diabetic retinopathy (DM/DR)., Methods: This cross-sectional, comparative study consisted of three study groups: eyes with (1) AMD and DM/DR, (2) AMD alone and (3) DM/DR alone. WF SS-OCTA (3×3, 6×6 and 12×12 mm) images were captured. Vascular metrics included foveal avascular zone (FAZ), vessel density (VD) and vessel skeletonised density (VSD). Mixed-effects multivariable regression models adjusted for age were performed by cohort and subgroup based on AMD and DR stages., Results: Our cohort included 287 eyes from 186 patients with an average age of 64±14.0 years old. Results revealed significantly reduced vascular metrics in concomitant AMD and DM/DR eyes (N=68) compared with AMD-only eyes (N=71) on all angiograms but not compared with DM/DR-only eyes (N=148). For example, when compared with AMD-only eyes, AMD and DM/DR eyes had significantly reduced VD (β=-0.03, p=0.016) and VSD (β=-1.09, p=0.022) on 12×12 mm angiograms, increased FAZ perimeter (β=0.51, p=0.025) and FAZ area (β=0.11, p=0.015) on 6×6 mm angiogram, and reductions in all VD and VSD metrics on 3×3 and 6×6 mm angiograms. However, only 3×3 mm angiogram FAZ metrics were significantly different when comparing DM/DR eyes with concomitant AMD and DM/DR eyes., Conclusion: WF SS-OCTA revealed significant reductions in retinal microvasculature metrics in AMD and DM/DR eyes compared with AMD-only eyes but not compared with DM/DR-only eyes., Competing Interests: Competing interests: JBM is a consultant for Alcon, Allergan, Carl Zeiss, Sunovion, Topcon and Genentech.

In this retrospective case series on neovascular age-related macular degeneration (nAMD), we aimed to improve Choroidal Neovascularization (CNV) visualization in Optical Coherence Tomography Angiography (OCTA) scans by addressing segmentation errors. Out of 198 eyes, 73 OCTA scans required manual segmentation correction. We compared uncorrected scans to those with minimal (2 corrections), moderate (10 corrections), and detailed (50 corrections) efforts targeting falsely segmented Bruch's Membrane (BM). Results showed that 55% of corrected OCTAs exhibited improved quality after manual correction. Notably, minimal correction (2 scans) already led to significant improvements, with additional corrections (10 or 50) not further enhancing expert grading. Reduced background noise and improved CNV identification were observed, with the most substantial improvement after two corrections compared to baseline uncorrected images. In conclusion, our approach of correcting segmentation errors effectively enhances image quality in OCTA scans of nAMD. This study demonstrates the efficacy of the method, with 55% of resegmented OCTA images exhibiting enhanced quality, leading to a notable increase in the proportion of high-quality images from 63 to 83%., (© 2024.

Background and Objectives : Age-related macular degeneration (AMD) is one of the leading causes of central vision loss among elderly patients, and its dry form accounts for the majority of cases. Although several causes and mechanisms for the development and progression of AMD have previously been identified, the pathogenesis of this complex disease is still not entirely understood. As inflammation and immune system involvement are strongly suggested to play a central role in promoting the degenerative process and stimulating the onset of complications, we aimed to analyze the frequency of serum anti-retinal (ARAs) and anti-endothelial cell antibodies (AECAs) in patients with dry AMD and to determine their relationship with the clinical features of the disease, notably the area of geographic atrophy (GA). Materials and Methods : This study included 41 patients with advanced-stage dry AMD and 50 healthy controls without AMD, matched for gender and age. ARAs were detected by indirect immunofluorescence using monkey retina as an antigen substrate, and the presence of AECAs was determined using cultivated human umbilical vein endothelial cells and primate skeletal muscle. Results: ARAs were detected in 36 (87.8%) AMD patients (titers ranged from 1:20 to 1:320) and in 16 (39.0%) (titers ranged from 1:10 to 1:40) controls ( p = 0.0000). Twenty of the forty-one patients (48.8%) were positive for AECAs, while in the control group, AECAs were present only in five sera (10.0%). The titers of AECAs in AMD patients ranged from 1:100 to 1:1000, and in the control group, the AECA titers were 1:100 ( p = 0.0001). There were no significant correlations between the presence of AECAs and disease activity. Conclusions : This study demonstrates a higher prevalence of circulating AECAs in patients with dry AMD; however, no correlation was found between the serum levels of these autoantibodies and the area of GA.

Introduction: Patients with advanced age-related macular degeneration (AMD) frequently experience loss to follow-up (LTFU), heightening the risk of vision loss from treatment delays. This study aimed to identify factors contributing to LTFU in patients with advanced AMD and assess the effectiveness of telephone-based outreach in reconnecting them with eye care., Methods: A custom reporting tool identified patients with advanced AMD who had not returned for eye care between 31 October 2021 and 1 November 2022. Potentially LTFU patients were enrolled in a telephone outreach programme conducted by a telehealth extender to encourage their return for care. Linear regression analysis identified factors associated with being LTFU and likelihood of accepting care post-outreach., Results: Out of 1269 patients with advanced AMD, 105 (8.3%) did not return for recommended eye care. Patients LTFU were generally older (89.2 ± 8.9 years vs. 87.2 ± 8.5 years, p = 0.02) and lived farther from the clinic (25 ± 43 miles vs. 17 ± 30 miles, p = 0.009). They also had a higher rate of advanced dry AMD (26.7% vs. 18.5%, p = 0.04) and experienced worse vision in both their better-seeing (0.683 logMAR vs. 0.566 logMAR, p = 0.03) and worse-seeing (1.388 logMAR vs. 1.235 logMAR, p = 0.04) eyes. Outreach by a telehealth extender reached 62 patients (59%), 43 through family members or healthcare proxies. Half of the cases where a proxy was contacted revealed that the patient in question had died. Among those contacted directly, one third expressed willingness to resume eye care (20 patients), with 11 scheduling appointments (55%). Despite only two patients returning for in-person eye care through the intervention, the LTFU rate halved to 4.4% by accounting for those patients who no longer needed eye care at the practice., Conclusions: There is a substantial risk that older patients with advanced AMD will become LTFU. Targeted telephone outreach can provide a pathway for vulnerable patients to return to care., (© 2024 College of Optometrists.)

Purpose: To describe a representative case and review the literature on paracentral acute middle maculopathy (PAMM) and giant cell arteritis (GCA)., Methods: A review of the English-language ophthalmic literature was performed using the search terms of PAMM, giant cell arteritis, and temporal arteritis., Results: A 72-year-old woman with PAMM as the presenting ophthalmic manifestation of GCA was described with a review of the prior cases from the literature. It was found that there were 26 cases of PAMM in GCA. In 19 of 26 cases, PAMM was associated with no other fundus abnormalities and was only seen on multimodal imaging including optical coherence tomography., Conclusion: PAMM can cause acute paracentral visual loss, and GCA should be suspected in all cases of PAMM of the elderly patients, even when isolated and not associated with constitutional symptoms of GCA.

This retrospective study aimed to determine the short-term efficacy and safety of brolucizumab treatment for recalcitrant neovascular age-related macular degeneration (nAMD) in a real-world setting in Taiwan. Recalcitrant nAMD patients who were treated with brolucizumab from November 2021 to August 2022 at Taipei Veterans General Hospital were included. Patients were followed for 3 months after switching to brolucizumab. The primary outcomes were changes in mean best-corrected visual acuity (BCVA) and central retinal thickness (CRT) from baseline to the third month. The secondary outcomes included the incidence of intraocular inflammation (IOI), proportion of patients with subretinal and intraretinal fluid (SRF and IRF), and change in pigment epithelial detachment (PED) height from baseline to the third month. The significance level was considered as p < .05 in all tests. A total of 38 patients (40 eyes) with a mean (±SD) age of 76.3 (±10.84) years were included. The baseline BCVA was 0.92±0.64 logMAR, and the CRT and PED height were 329.0±171.18 and 189.8±114.94 um, respectively. The patients had a significant reduction in CRT and resolution of IRF and SRF from baseline to the third month. There were numerical improvements in mean BCVA and PED height, but they were not significant. The percentages of achieving at least 0.1, 0.2, and 0.3 logMAR (equivalent to 5, 10, 15 ETDRS letters) visual gain were 50%, 37.5%, and 30%, respectively, during the first 3 months of follow-up. No IOI occurred in these patients. This study demonstrated that brolucizumab had good short-term structural and functional efficacy in recalcitrant nAMD patients., Competing Interests: I have read the journal’s policy and the authors of this manuscript have the following competing interests: C.C.W.: consultant of Bayer and Novartis; S.C.C: nil; T.C.L.: consultant of Roche, Bayer, Norvartis, and Allergan; Y.M.H.: nil; Y.B.C.: consultant of Bayer; D.K.H.: consultant of Roche, Bayer, Norvartis, and Allergan; S.J.C.: consultant of Roche, Bayer, receive travel grant and lecture fee from Novartis, Allergan., (Copyright: © 2024 Weng et al.

Purpose: To investigate the pace of visual acuity loss in myopic maculoschisis eyes with or without macular detachment and identify associated risk factors., Methods: One thousand three hundred and thirty-four eyes of 991 patients with high myopia were reviewed. A new myopic traction maculopathy staging system classified four retinal stages and three foveal stages. To the myopic traction maculopathy eyes with normal fovea, maculoschisis with and without macular detachment was defined as Stage 3a and Stages 1a, 2a respectively., Results: One hundred and ten (8.25%) eyes with maculoschisis were included, with a follow-up of 24.00 ± 17.47 months. Of them, 84 (76.36%) were Stages 1a, 2a, and 26 (23.64%) were Stage 3a. The visual acuity loss per year during the follow-up period was similar between eyes with Stages 1a, 2a and Stage 3a (3.13 ± 12.21 vs. 3.41 ± 18.42 letters, P = 0.930). Multivariate analyses revealed that vitreomacular interface factors were significantly associated with visual acuity loss during the follow-up, no matter in Stages 1a, 2a or Stage 3a ( P = 0.039 and P = 0.038, respectively). In the Stages 1a, 2a group, the percentage of eyes that lost at least 10 letters at the final visit compared with the baseline visual acuity was higher in eyes with vitreomacular interface factors than in those without vitreomacular interface factors (13 eyes, 50.00% vs. 14 eyes, 24.14%, P = 0.019)., Conclusion: No differences were found in visual acuity loss pace between Stages 1a, 2a and Stage 3a. Surgical intervention or at least more intensive follow-up should be considered for Stages 1a, 2a eyes with vitreomacular interface factors, to promote a more favorable visual outcome.

Purpose: To investigate the sociodemographic profile, the association with retinal vascular diseases (RVD) and systemic comorbidities, and visual outcomes of patients with paracentral acute middle maculopathy (PAMM) in a large, ethnically diverse single-center cohort., Design: Retrospective cohort study., Methods: Electronic health record query for all patients presenting with PAMM at Moorfields Eye Hospital, London, was completed. Detailed demographic, clinical, and systemic information were collected and analyzed., Results: A total of 78 eyes of 78 patients with confirmed PAMM were included in the study. Forty patients (51.3%) presented with no RVD, 20 patients (25.6%) with retinal vein occlusion (RVO), 16 patients (20.5%) with retinal artery occlusion (RAO), and 2 patients (2.6%) with concomitant RAO and RVO. Patients with PAMM+RAO were older than those with RVO (P = .02) and more likely to have a history of major adverse cardiovascular events (MACE) (P = .01), with a significantly worse presenting best corrected visual acuity (BCVA) (20/50) compared to patients with RVO (P = .02) and no RVD (P < .001). Individuals with isolated PAMM had a significantly higher prevalence of previous MACE (P = .04) and sickle cell disease (SCD) (P = .04) compared to those with RVO. At the last follow-up, 64 patients (85.3%) had a good BCVA (>20/32)., Conclusions: The significant association of PAMM with RVD supports the hypothesis of an ischemic etiology. Individuals with isolated PAMM had a higher prevalence of MACE and SCD. Thus, it is important to prompt immediate referral for a comprehensive systemic evaluation. Across the whole cohort, PAMM was associated with good BCVA improvement during follow-up, indicating a good visual prognosis., (Copyright © 2023 The Author(s). Published by Elsevier Inc.

Objective: The objective of this study was to determine whether high-resolution OCT (HR-OCT) could enhance the identification and classification of atrophic features in age-related macular degeneration (AMD) compared with standard resolution OCT., Design: Prospective, observational, cross-sectional study., Subjects: The study included 60 eyes from 60 patients > 60 years of age with a diagnosis of AMD., Methods: The participants underwent volume OCT scanning using HR-OCT and standard resolution OCT devices. Trained graders reviewed and graded the scans, identifying specific regions of interest for subsequent analysis., Main Outcome Measures: The study focused on identifying and classifying complete retinal pigment epithelium (RPE) and outer retinal atrophy (cRORA), incomplete RORA (iRORA), and other nonatrophic AMD features. Additionally, qualitative and quantitative features associated with atrophy were assessed., Results: The agreement among readers for classifying atrophic lesions was substantial to perfect for both HR-OCT (0.88) and standard resolution OCT(0.82). However, HR-OCT showed a higher accuracy in identifying iRORA lesions compared with standard OCT. Qualitative assessment of features demonstrated higher agreement for HR-OCT, particularly in identifying external limiting membrane (ELM) (0.95) and ellipsoid zone (EZ) disruption (0.94). Quantitative measurements of features such as hypertransmission defects, RPE attenuation/disruption, EZ disruption width, and ELM disruption width showed excellent interreader agreement with HR-OCT (> 0.90 for all features) but only moderate agreement with standard OCT (0.51-0.60)., Conclusions: The study results suggest that HR-OCT improves the accuracy and reliability of classifying and quantifying atrophic lesions associated with AMD compared with standard resolution OCT. The quantitative findings in particular may have implications for future research and clinical practice, especially with the availability of therapeutic agents for treating geographic atrophy and the development of commercially available HR-OCT devices., Financial Disclosure(s): Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (Copyright © 2023 American Academy of Ophthalmology.

Purpose: The aim of this study was to compare the responses of type 1 and type 2 macular neovascularizations (MNV) caused by neovascular type age-related macular degeneration (n-AMD) to intravitreal anti-vascular endothelial growth factor (VEGF) treatments using quantitative parameters determined by optical coherence tomography (OCT). Additionally, it was also intended to assess the connections between these quantitative parameters and changes in best-corrected visual acuity (BCVA) and the number of intravitreal anti-VEGF injections required within a year., Materials and Methods: In our retrospective and observational study, the data of 90 eyes of 90 patients diagnosed with n-AMD and treated with intravitreal anti-VEGF with the "Pro re nata" method were evaluated. Subtypes of existing MNVs were distinguished with previously taken optical coherence tomography angiography (OCTA) images. In spectral domain OCT examinations, central macular thickness (CMT) and central macular volume (CMV) values were recorded at baseline and 12th month. The number of intravitreal anti-VEGF injections during the 12 month follow-up period was also recorded for each patient. Obtained data were compared between MNV types., Results: Of the n-AMD cases examined in the study, 56.66% had type 1 MNV and 43.34% had type 2 MNV. The mean baseline BCVA logMAR values in eyes with type 2 MNV (1.15 ± 0.43) were higher than those observed in eyes with type 1 MNV (0.76 ± 0.42) (p = 0.001). Similarly, mean baseline CMT and CMV values in eyes with type 2 MNV were higher than those observed in eyes with type 1 MNV (respectively 424.89 ± 49.46 μm vs. 341.39 ± 37.06 μm; 9.17 ± 0.89 μm 3 vs. 8.49 ± 0.53 μm 3 ; p < 0.05). After 12 months of treatment, logMAR values of BCVA (0.86 ± 0.42) in subjects with type 2 MNV were higher than those in subjects with type 1 MNV (0.57 ± 0.37) (p = 0.001). Mean CMT and CMV values at 12th month in subjects with type 2 MNV (379.11 ± 46.36 μm and 8.66 ± 0.79 μm 3 , respectively) were observed to be higher than those with type 1 MNV (296.95 ± 33.96 μm and 8.01 ± 0.52 mm 3 , respectively) (p < 0.05). In type 2 MNVs, positive correlations were observed between both baseline and 12th month BCVA logMAR values and baseline CMV (p < 0.05). Similarly, in type 2 MNVs, a positive correlation was observed between 12th month BCVA logMAR values and 12th month CMV (p < 0.05). The total number of intravitreal anti-VEGF injections at 12 months was similar in both groups (p = 0.851)., Conclusion: In this study, in which we performed a subtype analysis of MNV cases, we observed that the visual function was worse at the beginning and the end of the 12th month, and the CMT and CMV values were higher in the type 2 MNV group compared to the type 1 MNV cases. In addition, we found significant correlations between BCVA logMAR values and CMV values in type 2 MNV cases. In the follow-up of these cases, CMT, which is a more widely used quantitative method, and CMV, which is a newer OCT measurement parameter, may be more useful in patient follow-up and evaluation of treatment efficacy, especially for type 2 MNV cases., (© 2024.

Purpose: To explore the occurrence of macular atrophy (MA) in eyes with age-related macular degeneration (AMD)-associated Type 3 macular neovascularization (MNV) treated with anti-vascular endothelial growth factor (anti-VEGF) therapy. Importantly, we aimed at describing the existence of separate pathways leading to MA., Methods: We analyzed 41 participants (41 eyes) with treatment-naïve Type 3 MNV who were followed up for a duration of 12 months after beginning the anti-VEGF therapy. At the one-year follow-up visit, optical coherence tomography (OCT) scans were reviewed for the presence of MA. MA regions of interest (ROIs) were selected and traced back to their original dominant baseline lesion (i.e., precursor) through previous serially captured OCT scans. Baseline lesions included precursors associated with the development and exudation of MNV and causes external to the neovascularization itself., Results: At the one-year follow-up visit, MA was graded to be present in 38 (92.7%) out of 41 eyes. These 78 MA ROIs were divided into two subgroups according to the precursor lesion, yielding a group of 53 MA lesions with precursors associated with the development and exudation of MNV (i.e., MA caused by physical harm from Type 3 neovessels, collapse of a serous pigment epithelium detachment, and fibrosis) and 25 MA regions with precursors external to the neovascularization itself (i.e., MA caused by drusen or subretinal drusenoid deposits)., Conclusions: Eyes with Type 3 MNV are commonly complicated by MA and precursors of MA include causes associated with the development and exudation of MNV, as well as lesions unrelated to the neovascularization process itself.

Importance: Individuals with high myopia younger than 18 years are at relatively high risk of progressively worsening myopic maculopathy. Additional studies are needed to investigate the progression of myopic maculopathy in this age group, as well as the risk factors associated with progression., Objective: To investigate the 4-year progression of myopic maculopathy in children and adolescents with high myopia, and to explore potential risk factors., Design, Setting, and Participants: This hospital-based observational study with 4-year follow-up included a total of 548 high myopic eyes (spherical power -6.00 or less diopters) of 274 participants aged 7 to 17 years. Participants underwent comprehensive ophthalmic examination at baseline and 4-year follow-up. Myopic maculopathy was accessed by the International Photographic Classification and Grading System. The data analysis was performed from August 1 to 15, 2023., Main Outcomes and Measures: The progression of myopic maculopathy progression over 4 years and associated risk factors., Results: The 4-year progression of myopic maculopathy was found in 67 of 548 eyes (12.2%) of 274 participants (138 girls [50.4%] at baseline and 4-year follow-up) with 88 lesion changes, including new signs of the tessellated fundus in 16 eyes (18.2%), diffuse atrophy in 12 eyes (13.6%), patchy atrophy in 2 eyes (2.3%), lacquer cracks in 9 eyes (10.2%), and enlargement of diffuse atrophy in 49 eyes (55.7%). By multivariable analysis, worse best-corrected visual acuity (odds ratio [OR], 6.68; 95% CI, 1.15-38.99; P = .04), longer axial length (AL) (OR, 1.73; 95% CI, 1.34-2.24; P < .001), faster AL elongation (OR, 302.83; 95% CI, 28.61-3205.64; P < .001), and more severe myopic maculopathy (diffuse atrophy; OR, 4.52; 95% CI, 1.98-10.30; P < .001 and patchy atrophy; OR, 3.82; 95% CI, 1.66-8.80; P = .002) were associated with myopic maculopathy progression., Conclusions and Relevance: In this observational study, the progression of myopic maculopathy was observed in approximately 12% of pediatric high myopes for 4 years. The major type of progression was the enlargement of diffuse atrophy. Risk factors for myopic maculopathy progression were worse best-corrected visual acuity, longer AL, faster AL elongation, and more severe myopic maculopathy. These findings support consideration of follow-up in these individuals and trying to identify those at higher risk for progression.

Background: This study aimed to assess the vision-related quality of life (VRQol) of patients with age-related macular degeneration (AMD) and to evaluate VRQol according to different types of AMD., Methods: In this small-scale, single-center, prospective investigation, patients with AMD and subjects without any signs of macular disease were asked to complete the NEI-VFQ-39. A total of 159 subjects were included and grouped according to the type of AMD as follows: 40 patients with dry AMD in both eyes (DD), 40 patients with exudative AMD in one eye (DE), 41 patients with exudative AMD in both eyes (EE), and 38 subjects without any signs of macular disease, as a control group (CG)., Results: The average age of the participants was 76 ± 7 years, and 44% were male. Most participants were retired (22.4%), and 75% of patients were initially diagnosed by their ophthalmologist. All the AMD groups had significantly worse overall VRQol than the CG. For general vision, near vision, mental health, and role difficulties, all the AMD groups had significantly lower scores than the CG. For distance vision, color vision, peripheral vision, driving difficulties, dependency, and social functioning, only patients in the EE and DE groups had significantly worse scores than the CG. The type of retinal fluid in patients with exudative AMD had no effect on overall VRQol; however, we found that the presence of pigment epithelial detachment could be associated with more role difficulties, such as completing work or working long hours., Conclusion: All types of AMD had a negative effect on vision-related quality of life. This effect was significantly more pronounced in patients with exudative AMD in at least one eye. However, the type of retinal fluid in patients with exudative AMD had no influence on their overall vision-related quality of life., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

Purpose: To analyze anatomic and functional response to intravitreal brolucizumab in age-related macular degeneration recalcitrant to previous intravitreal anti-VEGF therapies., Methods: In this monocentric, one arm, retrospective study, eyes affected by neovascular age-related macular degeneration (nAMD) resistant to other intravitreally injected anti-vascular endothelial growth factor inhibitors were switched to intravitreal brolucizumab. All patients underwent ophthalmological examinations at baseline and in regular follow-up intervals. Best registered visual acuity (BRVA), Goldmann tonometry, intraocular pressure (IOP), central retinal thickness (CRT) and pigment epithelial detachment (PED) characteristics were analyzed at initiation of anti-VEGF treatment, at treatment switch, and at the end of brolucizumab loading phase., Results: The study included 20 eyes of 18 consecutively treated patients (age: 77 ± 6 years). All eyes had macular neovascularization with PED. Previous treatments included intravitreal aflibercept, bevacizumab, and ranibizumab and had not resulted in a significant improvement in BRVA (0.5 ± 0.5 logMAR vs 0.5 ± 0.6 logMAR) or mean CRT (320 ± 60 µm vs 313 ± 83 µm) up to treatment switch to brolucizumab. At the end of the brolucizumab loading phase, there was significant improvement for both BRVA (0.3 ± 0.2 logMAR, P < 0.05) and CRT (264 ± 55 µm, P  < 0.05). Under previous anti-VEGF therapy, there was a significant increase/deterioration in both PED area (2.68 mm 2 to 5.18 mm 2 , P  < 0.05) and PED volume (0.39 mm 3 to 1.07 mm 3 , P  < 0.05); however, both parameters improved after switching to brolucizumab (3.81 mm 2 and 0.37 mm 3 , P  < 0.05)., Conclusion: Our results suggest a favourable anatomical and visual response after treatment switch to brolucizumab in patients with nAMD refractory to previous anti-VEGF agents., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose: The primary aim was to describe the patterns of paramacular involvement, not yet reported but that optical coherence tomography angiography can now detect in patients with sickle cell disease. The secondary aim was to search arguments concerning the physiopathogeny of paramacular involvement., Methods: This institutional cohort retrospective study was conducted in a Referral Center for Ophthalmological Rare Diseases. Follow-up included an ophthalmologic examination with optical coherent tomography and optical coherent tomography angiography., Results: One hundred and thirty-two patients with SCD were included. Typical sickle cell maculopathy was observed in temporal area in 84 eyes (40.0%) of SS patients and eight eyes (14.8%) of SC patients ( P < 0.001). Enlargement of the foveal avascular zone was observed in 10 eyes of eight SS patients. Two atypical parafoveal abnormalities were found in SS patients only. The first one consisted of macular thinning with normal vascularization in 15 eyes of 11 patients. The second atypical maculopathy was large areas of loss of vascularization without retinal thinning 10 eyes of six patients. Multivariate analysis did not show a statistically significant relation between the peripheral sickle retinopathy stage and the different type of sickle cell maculopathy ( P = 0.21)., Conclusion: Those atypical sickle cell maculopathy may correspond to early forms preceding a typical sickle cell disease maculopathy (SCDM). This would point toward several physiopathogenic mechanisms. The first one included the existence of ischemia that can be related to anemia. Presence of retinal thinning without vascular involvement point out to a neurogenic mechanism.

Background: To investigate the prevalence of macular lesions associated with age-related macular degeneration (AMD) in eyes with pachydrusen., Methods: Clinical records and multimodal imaging data of patients over 50 years old with drusen or drusenoid deposits were retrospectively assessed, and eyes with pachydrusen were included in this study. The presence of AMD features, including drusen or drusenoid deposits, macular pigmentary abnormalities, geographic atrophy (GA), and macular neovascularization (MNV), were evaluated., Results: Out of 967 eyes of 494 patients with drusen or drusenoid deposits, 330 eyes of 183 patients had pachydrusen (34.1%). The mean age was 66.1 ± 9.3 years, and the subfoveal choroidal thickness (SFCT) was 292.7 ± 100.1 μm. The mean number of pachydrusen per eye was 2.22 ± 1.73. The majority of eyes with pachydrusen had no other drusen or drusenoid deposits (95.2%). Only 16 eyes (4.8%) had other deposits, including soft drusen (10 eyes, 3.0%), cuticular drusen (3 eyes, 0.9%), and reticular pseudodrusen (RPD; 3 eyes, 0.9%). Macular pigmentary abnormalities accompanied pachydrusen in 68 eyes (27.4%). None of the eyes had GA, and 82 eyes (24.8%) had MNV. The majority of MNV was polypoidal choroidal vasculopathy (PCV; 65 eyes, 19.7%), followed by type 1 (10 eyes, 3.0%), type 2 (5 eyes, 1.5%), and type 3 MNV (2 eyes, 0.6%)., Conclusions: Eyes with pachydrusen in Korean population have several characteristic AMD lesions in low frequencies. These findings indicate that pachydrusen might have diagnostic and prognostic values that are different from those of other drusen or drusenoid deposits., (© 2023.

Purpose: Our aim was to evaluate whether patients with age-related macular degeneration (AMD) and cooccurrent amblyopia are more likely to have diseases diagnosed on both the ipsilateral and the contralateral side in a large Austrian database., Design: Retrospective cross-sectional study., Methods: Setting: Institutional practice., Patient Population: Medical records of all patients who visited the Department of Ophthalmology of the Medical University of Graz between December 1996 and June 2021 were searched for the co-occurrence of AMD and amblyopia., Main Outcome Measures: Data from patients with AMD diagnosed on 1 eye side were used for further analysis. Spectral-domain optical coherence tomography images were analyzed to confirm the lateral asymmetry of AMD., Results: A total of 327,443 patients were screened for the co-occurrence of AMD and amblyopia. Of them, 8742 patients had AMD diagnosed on 1 eye side and 5051 patients had unilateral amblyopia. In total, 163 patients were found to have AMD diagnosed on 1 side and unilateral amblyopia in combination. Of these, 126 patients had AMD and amblyopia on contralateral sides and 37 had AMD and amblyopia on the ipsilateral side (P < .001)., Conclusions: Less amblyopic patients had AMD diagnosed on the amblyopic eye compared with the nonamblyopic eye. In cases of lateral asymmetry, the nonamblyopic eye is more likely to have the more advanced form of AMD., (Copyright © 2023 The Authors. Published by Elsevier Inc. All rights reserved.)

Introduction: Sickle cell disease (SCD) is one of the most common genetic disorders in the UK, with over 15 000 people affected. Proliferative sickle cell retinopathy (SCR) is a well-described complication of SCD and can result in significant sight loss, although the prevalence in the UK is not currently known. There are currently no national screening guidelines for SCR, with wide variations in the management of the condition across the UK., Methods and Analysis: The Sickle Eye Project is an epidemiological, cross-sectional, non-interventional study to determine the prevalence of visual impairment due to SCR and/or maculopathy in the UK. Haematologists in at least 16 geographically dispersed hospitals in the UK linked to participating eye clinics will offer study participation to consecutive patients meeting the inclusion criteria attending the sickle cell clinic. The following study procedures will be performed: (a) best corrected visual acuity with habitual correction and pinhole, (b) dilated slit lamp biomicroscopy and funduscopy, (c) optical coherence tomography (OCT), (d) OCT angiography where available, (e) ultrawide fundus photography, (f) National Eye Institute Visual Function Questionnaire-25 and (g) acceptability of retinal screening questionnaire. The primary outcome is the proportion of people with SCD with visual impairment defined as logarithm of the minimum angle of resolution ≥0.3 in at least one eye. Secondary outcomes include the prevalence of each stage of SCR and presence of maculopathy by age and genotype; correlation of stage of SCR and maculopathy to severity of SCD; the impact of SCR and presence of maculopathy on vision-related quality of life; and the acceptability to patients of routine retinal imaging for SCR and maculopathy., Ethics and Dissemination: Ethical approval was obtained from the South Central-Oxford A Research Ethics Committee (REC 23/SC/0363). Findings will be reported through academic journals in ophthalmology and haematology., Competing Interests: Competing interests: CD reports receiving institutional research grant, consulting fees and speaker fees from Roche.

Purpose: To determine prevalence of anisomyopia (axial length (AL) difference ≥2.5 mm) among high myopes ((HMs), defined by spherical equivalent of ≤6.0 diopters or AL ≥ 26.5 mm). To characterise the shorter anisomyopic eye (SAE) and evaluate if pathologic myopia (PM) in the longer anisomyopic eye (LAE) was associated with increased risk of PM in the SAE., Methods: 1168 HMs were recruited from Singapore National Eye Centre clinic for this cross-sectional study. Biometry, fundus photography and swept-source optical coherence tomography were performed. Patients with high axial anisomyopia were identified. Structural characteristics and presence of PM were described. Stepwise multivariate regression explored associations between PM in the LAE and pathology in the SAE, controlling for confounding variables., Results: Prevalence of anisomyopia was 15.8% (184 of 1168 patients). Anisomyopic patients (age 65.8±13.5 years) had mean AL of 30.6±2.0 mm and 26.2±2.3 mm in the LAE and SAE, respectively. 52.7% of SAEs had AL < 26.5 mm. Prevalence of myopic macular degeneration, macula-involving posterior staphyloma (PS), myopic traction maculopathy (MTM) and myopic choroidal neovascularisation (mCNV) in the SAE was 52.2%, 36.5%, 13.0% and 8.2%, respectively. Macular hole in the LAE was associated with increased risk of MTM in the SAE (OR=4.88, p=0.01). mCNV in the LAE was associated with mCNV in the SAE (OR=3.57, p=0.02). PS in the LAE was associated with PS in the SAE (OR=4.03, p<0.001)., Conclusions: Even when controlled for AL, PM complications in the LAE predict similar PM complications in the SAE. Patients with high axial anisometropia with PM in the LAE should be monitored carefully for complications in the SAE., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.
