Purpose: To evaluate 2-year efficacy, durability, and safety of faricimab in the TENAYA Japan subgroup and pooled global TENAYA/LUCERNE cohort of patients with neovascular age-related macular degeneration (nAMD). Methods: Subgroup analysis of TENAYA/LUCERNE (NCT03823287/NCT03823300): phase III, multicentre, randomised, active comparator–controlled, double-masked, non-inferiority trials. Treatment-naïve patients aged ≥ 50 years with nAMD were randomised (1:1) to intravitreal faricimab (6.0 mg up to every 16 weeks [Q16W] after 4 initial Q4W doses) or aflibercept (2.0 mg Q8W after 3 initial Q4W doses). Outcomes were assessed through year 2 for the TENAYA Japan subgroup (N = 133) and global pooled TENAYA/LUCERNE cohort (N = 1329). Results: Vision and anatomic improvements achieved with faricimab at year 1 were maintained over 2 years and were generally comparable between the TENAYA Japan subgroup and pooled TENAYA/LUCERNE cohort. Adjusted mean best-corrected visual acuity (BCVA) change from baseline at year 2 for the TENAYA Japan subgroup and global pooled TENAYA/LUCERNE cohort was +7.1 (3.7–10.5) and +4.4 (3.2–5.5) letters in the faricimab arm, respectively, and +5.2 (1.9–8.6) and +4.3 (3.1–5.4) letters in the aflibercept arm, respectively. At week 112, the proportion of faricimab-treated patients on Q16W dosing was 61.0% and 63.1% in the TENAYA Japan subgroup and pooled TENAYA/LUCERNE cohort. Faricimab was well tolerated through year 2. Conclusion: Year 2 TENAYA Japan subgroup findings for faricimab were generally consistent with the pooled global TENAYA/LUCERNE results in patients with nAMD. Vision and anatomical benefits with faricimab were similar to those with aflibercept but with fewer injections. [ABSTRACT FROM AUTHOR]

Purpose: To assess 6-month outcomes of switching from aflibercept to faricimab in eyes with refractory neovascular age-related macular degeneration (nAMD) previously requiring monthly injections. Methods: This multicenter retrospective study examined nAMD eyes receiving monthly aflibercept injections switched to faricimab administered monthly up to 4 injections followed by injections at a minimum of 2-month intervals as per drug labeling. Data regarding age, sex, number of previous injections, treatment intervals, and best-corrected visual acuity (BCVA) were collected. Central retinal thickness (CRT), subfoveal choroidal thickness (SFCT), and maximal pigment epithelial detachment (PED) height were measured by optical coherence tomography. Results: The study included 130 eyes of 124 patients. At 6 months, 53 eyes (40.8%) continued on faricimab treatment (Group 1), while 77 eyes (59.2%) discontinued faricimab for various reasons (Group 2) the most common being worse exudation. There were no significant differences between the two groups at baseline. In Group 1, CRT and SFCT significantly decreased at 1 month (P = 0.013 and 0.008), although statistical significance was lost at 6 months (P = 0.689 and 0.052). BCVA and maximal PED height showed no significant changes; however, mean treatment intervals were extended from 4.4 ± 0.5 weeks at baseline to 8.7 ± 1.7 weeks at 6 months (P < 0.001) in Group 1. No clear predictors of response were identified. Conclusion: Switching from aflibercept to faricimab allowed for extension of treatment intervals from monthly to bimonthly in roughly 40% of eyes, suggesting that faricimab may be considered in refractory nAMD cases.

Background: To analyze clinical features, treatment, complications, and visual outcomes of ocular sarcoidosis at a tertiary center in Tokyo. Methods: Clinical records of 53 patients with ocular sarcoidosis ("definite" or "presumed") presenting between 2013 and 2018 to the Kyorin Eye Center were retrospectively reviewed. Diagnosis was based on the revised criteria of the International Workshop on Ocular Sarcoidosis. Results: Definite (biopsy-proven) disease was present in 87% of patients and presumed disease in 13%. The mean age at presentation was 58 years (13–81 years) and 68% were women. The mean follow-up was 34 months (6–70 months). Forty-five patients (85%) had panuveitis, and the most common ocular clinical sign suggestive of ocular sarcoidosis was bilaterality (92%). Ocular complications were observed in 93 eyes (85%), most commonly cataract (73%), epiretinal membrane (24%), macular edema (24%) and glaucoma (19%). Thirty-one eyes (30%) underwent cataract surgery and 12 eyes (12%) underwent pars plana vitrectomy. Ten patients (19%) received systemic corticosteroid therapy and 33 eyes (32%) received periocular corticosteroid injections. The best-corrected visual acuity was 1.0 or better in 51% of eyes at presentation, 57% at 6 months, 50% at 12 months, and 58% at 36 months. Conclusions: The majority of ocular sarcoidosis patients were women, had bilateral disease and panuveitis involvement. Most eyes maintained good visual acuity, although surgical interventions for cataract and epiretinal membrane were common. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate changes in choroidal blood flow in patients with Vogt-Koyanagi-Harada (VKH) disease after initiation of corticosteroid treatment. Methods: Fourteen patients (10 men and 4 women) with acute VKH disease followed for 2 years were retrospectively reviewed; only right eyes were included in the analysis. Mean blur rate (MBR) in the macula was measured by laser speckle flowgraphy (LSFG) and central choroidal thickness (CCT) was measured by optical coherence tomography (OCT), both prior to treatment and over 2 years after initiation of corticosteroid treatment. Results: Of 14 patients included in this study, 13 received initial treatment consisting of intravenous corticosteroid pulse therapy and one patient was treated using bilateral sub-Tenon injections of triamcinolone acetonide. Mean percentage change in MBR was significantly increased after initiation of treatment compared to pretreatment values (P < 0.001). Mean CCTs were significantly decreased after initiation of treatment, compared to pretreatment thicknesses (P < 0.001). There was no significant change in either MBR change or CCT at 1 month after initiation of treatment through 2 years of follow-up. The mean MBR percentage change was significantly higher in eyes with sunset glow fundus (SGF) compared to eyes without SGF at 1 year. Conclusion: With initiation of corticosteroid treatment in VKH disease patients, choroidal blood flow improved and was maintained for 2 years. However, the presence of SGF should be taken into consideration when interpreting MBR results in VKH disease patients. [ABSTRACT FROM AUTHOR]

Background/purpose: Observation of choroidal thickness after anti-vascular endothelial growth factor (VEGF) therapy may be important for the ideal management of neovascular age-related macular degeneration (AMD). This study investigated changes in subfoveal choroidal thickness (SCT) during loading doses of intravitreal injections of brolucizumab in eyes with neovascular AMD. Methods: This study included 73 eyes of 72 patients with neovascular AMD at five university hospitals in Japan. All 73 eyes underwent three monthly 6.0 mg intravitreal injections of brolucizumab at baseline, 1 month, and 2 months. The SCT at 3 months was evaluated using optical coherence tomography. Results: The 73 eyes were classified into the treatment-naïve group (43 eyes) and the switched group (30 eyes) that were switched from other anti-VEGF treatments. After three intravitreal injections of brolucizumab, SCT significantly decreased from 236.5 ± 98.8 µm at baseline to 200.4 ± 98.3 µm at 3 months (percent of baseline 84.7%, P < 0.001) in the treatment-naïve group. In the switched group, SCT also significantly decreased from 229.0 ± 113.2 μm at baseline to 216.9 ± 110.2 μm at 3 months (percent of baseline 94.7%, P = 0.039), although the decrease was not as marked compared to that of the treatment-naïve group. Conclusion: Intravitreal injections of brolucizumab for neovascular AMD significantly reduced the SCT in both the treatment-naïve and switched groups. Brolucizumab may cause significant anatomic changes in the choroid, particularly in treatment-naïve AMD eyes, possibly more than that previously reported for other anti-VEGF agents.

Purpose: To explore the relationship between retinal fluid status and best-corrected visual acuity (BCVA) in patients treated with intravitreal aflibercept (IVT-AFL) treat-and-extend (T&E) in the ALTAIR study. Methods: Outcomes were investigated according to overall fluid status at week 16 (predefined) and the relationship between any fluid, intraretinal fluid (IRF), subretinal fluid (SRF), or pigment epithelial detachment with BCVA at baseline, and weeks 16, 52, and 96 (post-hoc). The analyses involved treatment-naïve patients (N = 246) with exudative age-related macular degeneration (AMD), aged ≥ 50 years with BCVA of 73–25 Early Treatment Diabetic Retinopathy Study letters, who participated in the ALTAIR study. Results: The mean (standard deviation) change in BCVA from baseline to week 52 was + 10.6 (10.9) and + 6.5 (16.0) letters in patients without and with fluid at week 16, respectively; and to week 96 was + 9.1 (14.3) and + 4.3 (16.1) letters in patients without and with fluid at week 16, respectively. The last injection interval was 16 weeks in 33.6% and 2.0% (week 52), and 62.9% and 17.6% (week 96) of patients without or with fluid at week 16, respectively. At baseline, 35.7% of patients had IRF and 85.2% of patients had SRF, which decreased to 11.8% (IRF) and 31.7% (SRF) of patients, 8.5% (IRF) and 18.7% (SRF), and 6.5% (IRF) and 20.7% (SRF) at weeks 16, 52, and 96, respectively. Presence of IRF at all timepoints was associated with poorer BCVA than if IRF was absent, while the presence of SRF was not associated with poorer BCVA compared with the absence of SRF. Conclusion: IVT-AFL T&E dosing was effective at clearing fluid regardless of fluid type in ~ 80% of patients with exudative AMD. Patients without fluid at week 16 had numerically better BCVA than those with fluid at week 16. Over 60% of patients without fluid at week 16 achieved the maximum treatment interval of 16 weeks by study end, compared with < 20% of patients with fluid at week 16. IRF (weeks 16, 52, 96), although evident in a small number of patients, was associated with poorer BCVA, whereas SRF was not.

Purpose: The term "pachychoroid" refers to a newly described phenotype in which functional and structural choroidal changes are thought to play a key pathogenic role in a spectrum of related retinal disorders. A more detailed understanding of how the choroid is involved within this spectrum and a better knowledge of the most relevant clinical signs of the pachychoroid phenotype are important to differentiate these disorders from other retinal conditions. Our objectives are to provide a literature review of pachychoroid and the commonalities that may be present across pathologies included in the spectrum, and to provide details on the examination, monitoring, and management of these disorders. Methods: We searched the PubMed web platform to identify relevant studies using the following keywords: pachychoroid, pachychoroid pigment epitheliopathy, pachychoroid neovasculopathy, aneurysmal type 1 neovascularization, focal choroidal excavation, peripapillary pachychoroid syndrome, vasculopathy pachysclera, pachychoroid geographic atrophy, and pachydrusen. We selected 157 publications and identified the most important features related to pachychoroid. Results: The presence of hypertrophic or congested vessels in the choroid, not thickened choroid per se, under an area of reduced or absent choriocapillaris in the posterior pole seems to be the most salient feature of pachychoroid. However, other qualitative/quantitative features are needed to differentiate the uncomplicated pachychoroid from the pathological pachychoroid clinical spectrum, which may be associated with exudation, neovascularization, and/or retinal pigment epithelium and photoreceptor atrophy. Conclusions: The most salient feature of pachychoroid appears to be the presence of large vessels under an area of reduced or absent choriocapillaris. Knowledge of the features and pathogenesis of the different disorders in the pachychoroid spectrum may assist in the management of patients. [ABSTRACT FROM AUTHOR]

Purpose: Following the first wave of the COVID-19 pandemic in early 2020, the easing of strict measures to reduce its spread has led to a resurgence of cases in many countries at both the national and local level. This article addresses how guidance for ophthalmologists on managing patients with retinal disease receiving intravitreal injections of anti-vascular endothelial growth factor (VEGF) during the pandemic should be adapted to the local epidemic pressure, with more or less stringent measures implemented according to the ebb and flow of the pandemic. Methods: The Vision Academy's membership of international retinal disease experts analyzed guidance for anti-VEGF intravitreal injections during the COVID-19 pandemic and graded the recommendations according to three levels of increasing epidemic pressure. The revised recommendations were discussed, refined, and voted on by the 14-member Vision Academy Steering Committee for consensus. Results: Protocols to minimize the exposure of patients and healthcare staff to COVID-19, including use of personal protective equipment, physical distancing, and hygiene measures, should be routinely implemented and intensified according to local infection rates and pressure on the hospital/clinic or healthcare system. In areas with many COVID-19-positive clusters, additional measures including pre-screening of patients, postponement of non-urgent appointments, and simplification of complex intravitreal anti-VEGF regimens should be considered. Treatment prioritization for those at greatest risk of irreversible vision loss should be implemented in areas where COVID-19 cases are increasing exponentially and healthcare resources are strained. Conclusion: Consistency in monitoring of local infection rates and adjustment of clinical practice accordingly will be required as we move forward through the COVID-19 era. Ophthalmologists must continue to carefully weigh the risk–benefits to minimize the exposure of patients and healthcare staff to COVID-19, ensure that patients receive sight-saving treatment, and avoid the potential long-term impact of prolonged treatment postponement.

Purpose: There is an urgent need to address how to best provide ophthalmic care for patients with retinal disease receiving intravitreal injections with anti-vascular endothelial growth factor agents during the ongoing global COVID-19 pandemic. This article provides guidance for ophthalmologists on how to deliver the best possible care for patients while minimizing the risk of infection. Methods: The Vision Academy's Steering Committee of international retinal disease experts convened to discuss key considerations for managing patients with retinal disease during the COVID-19 pandemic. After reviewing the existing literature on the issue, members put forward recommendations that were systematically refined and voted on to develop this guidance. Results: The considerations focus on the implementation of steps to minimize the exposure of patients and healthcare staff to COVID-19. These include the use of personal protective equipment, adherence to scrupulous hygiene and disinfection protocols, pre-screening to identify symptomatic patients, and reducing the number of people in waiting rooms. Other important measures include triaging of patients to identify those at the greatest risk of irreversible vision loss and prioritization of treatment visits over monitoring visits where possible. In order to limit patient exposure, ophthalmologists should refrain from using treatment regimens that require frequent monitoring. Conclusion: Management of patients with retinal disease receiving intravitreal injections during the COVID-19 pandemic will require adjustment to regular clinical practice to minimize the risk of exposure of patients and healthcare staff, and to prioritize those with the greatest medical need. The safety of patients and healthcare staff should be of paramount importance in all decision-making. [ABSTRACT FROM AUTHOR]

Graph Dear Editor, We report short-term data on the development of intraocular inflammation (IOI) after intravitreal brolucizumab injection for exudative age-related macular degeneration (AMD) in Japanese patients in this letter. However, among 101 Japanese patients enrolled in the HAWK study, the rates were 2- to 3-fold higher; IOI in 12.9%, retinal vasculitis in 9.9%, and retinal vascular occlusion in 4.95% [[5]]. Of 127 eyes, 12 (9.4%) developed IOI consisting of anterior chamber cells and/or vitreous cells, with retinal vasculitis documented in 4 eyes (3.1%) and retinal vascular occlusion in 2 eyes (1.6%) (Table 1).

Purpose: Dehydroxymethylepoxyquinomicin (DHMEQ) is derived from the antibiotic, epoxyquinomicin C, and is a novel low molecular weight nuclear factor-κB (NF-κB) inhibitor. We investigated the effects of DHMEQ on the expression of chemokines and the intercellular adhesion molecule (ICAM)-1 induced by proinflammatory cytokines in cultures of the human corneal fibroblasts (HCFs). Methods: The cytotoxicity of DHMEQ on cultured HCFs was evaluated by cell proliferation assays. Cultures were exposed to interleukin (IL)-1β, and the production of IL-8 and monocyte chemoattractant protein (MCP)-1 was assessed by enzyme-linked immunosorbent assay. The degree of expression of ICAM-1 was measured by flow cytometry. The translocation of NF-κB p65 into the nucleus of HCFs was assessed by immunocytochemistry. Results: DHMEQ was not toxic to cultured HCFs at doses up to 10 μg/ml. DHMEQ significantly suppressed the production of both IL-8 and MCP-1 in IL-1β-stimulated HCFs. In addition, DHMEQ down-regulated ICAM-1 expression in IL-1β-stimulated HCFs in a dose-dependent manner. DHMEQ inhibited the IL-1β-induced nuclear accumulation of p65, a component of NF-κB, in HCFs. Conclusions: The suppression of inflammatory chemokines IL-8 and MCP-1 and inhibition of the expression of ICAM-1 in cultured HCFs by DHMEQ indicates that DHMEQ may have a therapeutic potential for treating ICAM-1 and chemokine-mediated corneal inflammatory disorders.

Background: The oral administration of type I interferons (IFNs) have been reported to reduce severity of inflammation in several animal models of autoimmune disease. This study examined whether oral administration of IFN-β is capable of modulating inflammation in experimental autoimmune uveoretinitis (EAU). Methods: EAU was induced in rats by immunization with interphotoreceptor retinoid-binding protein (IRBP) emulsified in complete Freund's adjuvant. Rats were treated with either varying doses (102, 103, 104 or 105 IU) of mouse recombinant IFN-β or phosphate-buffered saline for control, via direct oropharyngeal application once a day for 28 days starting 7 days before IRBP immunization. Intraocular inflammation was assessed by slit-lamp biomicroscopy and histopathological examination. Spleen cell proliferation response and cytokine production under IRBP stimulation were assessed. Spleen cell subpopulations were also measured. Results: IFN-β at doses of either 104 or 105 IU significantly reduced both the clinical and histopathological severity of EAU. Spleen cell proliferation and IFN-γ production from rats treated with 104 IU IFN-β were significantly decreased compared with controls. Furthermore, the proportion of both NK cells and NKT cells in the spleen of rats treated with IFN-β was increased compared with controls. Conclusion: These results suggest that the oral administration of IFN-β reduces inflammation in IRBP-mediated EAU and that the mechanism of this action may involve NK cells and NKT cells.
