To report the presenting features and outcomes in patients who developed bilateral acute iris transillumination (BAIT) or bilateral acute depigmentation of iris (BADI) following acute COVID-19 infection. Thirty two eyes of 16 patients were reviewed retrospectively. The severity of COVID-19 infection, use of antibiotics, time of onset of ocular symptoms; ocular signs, the course and surgical procedures were recorded. 24 eyes of 12 BAIT and eight eyes of four consecutive BADI patients were included. The mean time between infection and onset of ocular symptoms was 2.5±1.1 weeks. Nine patients were treated with oral moxifloxacin for COVID-19 prior to presentation. Trabeculectomy was performed in 7 eyes (21.8%) of 5 BAIT patients; in the postoperative follow-up, IOP was controlled without medication in 6 eyes, with medication in 1 eye. BADI and BAIT can also develop after COVID-19 infection. A significant proportion of BAIT patients may require glaucoma surgery. [ABSTRACT FROM AUTHOR]

To compare the quantitative measurements of the anterior chamber angle (ACA) and iris parameters in patients with juvenile open-angle glaucoma (JOAG), pigmentary glaucoma (PG), and healthy controls using anterior segment optical coherence tomography (AS-OCT).Methods: This was a retrospective, cross-sectional study of 25 eyes with JOAG, 25 eyes with PG, and 25 control eyes. Anterior chamber depth, angle-opening distance 500 and 750, trabecular-iris space 500 and 750, scleral spur angle, iris thickness (IT, measured at the thickest part), and iris bowing were obtained using AS-OCT (Visante" OCT 3.0 Model 1000, Carl Zeiss Meditec, Inc).Results: The quantitative ACA parameters were found to be significantly higher in JOAG and PG patients compared to healthy controls (P < 0.001); there was no significant difference between the eyes with JOAG and PG (P > 0.05). In eyes with JOAG and PG, there was significantly backward bowing of the iris in temporal and nasal angles compared to control subjects (P < 0.001). Median iris bowing was not significantly different between the patients with JOAG and PG (P > 0.05). The temporal and nasal angle iris thickness were significantly thinner in eyes with JOAG than the eyes with PG (P < 0.001) and age-matched control subjects (P < 0.001). The median IT did not differ between the patients with PG and control subjects (P > 0.05). In patients with JOAG, the intraocular pressure (IOP) was inversely correlated with IT (r = -0.43, P < 0.05).Conclusion: AS-OCT provided quantitative data on the ACA and iris parameters in JOAG and PG. The evaluation of the ACA and iris structures using AS-OCT revealed higher ACA measurements and posterior bowing of the iris in patients with JOAG and PG. Furthermore, the patients with JOAG were found to have thinner IT than the ones with PG and healthy controls. [ABSTRACT FROM AUTHOR]

To evaluate the microvasculature during remission in patients with pars planitis (PP-IU) and multiple sclerosis-associated intermediate uveitis (MS-IU) using optical coherence tomography angiography (OCT-A). Single-center, descriptive, case-control study was conducted. Adult patients (≥16 years) with IU in remission (PP-IU and MS-IU) and healthy age-sex matched healthy controls (HC) were enrolled to the study. Demographic/clinical features, best-corrected visual acuity (BCVA), ocular findings, neurological symptoms and preferred treatments were recorded. The presence of cystoid macular edema (CME) during follow-up was recorded. All IU patients in remission and HC subjects were scanned with OCT-A. Foveal avascular zone (FAZ) areas of superficial and deep capillary plexus (SCP/DCP) and vascular densities of SCP, DCP and choriocapillaris were obtained from OCT-A and compared between the groups. Sixty-nine eyes of 37 IU patients in remission and 20 HC were included (44 eyes/23 patients in PP-IU, 25/14 in MS-IU, 40/20 in HC). No statistically significant differences were observed in terms of demographic or clinical characteristics of the patients. The vascular density in the SCP was significantly reduced in the PP-IU and MS-IU groups compared to the HC group (p <.05). Nevertheless, there were no significant changes in any of the OCTA parameters between the IU groups. Uveitis duration was found to be correlated with enlargement of the FAZ area in PP-IU (p =.039). OCTA may not be useful in differentiating between PP-IU and MS-IU. Nevertheless, the primary implication in SCP potentially elucidates the pathogenesis of these two subtypes of IU, which are characterized by a shared pathogenesis. The monitoring of the FAZ area in the PP-IU group is valuable in terms of chronicity. [ABSTRACT FROM AUTHOR]

Background/ObjectivesSubjects/MethodsResultsConclusionsTo investigate the long-term efficacy and safety of adalimumab(ADA) in the treatment of patients with serpiginous choroiditis (SC) refractory to conventional therapy through quantitative parameters.A retrospective analysis was conducted on patients diagnosed with SC clinically and through fundus autofluorescence(FAF). Patients receiving ADA treatment were included. Demographic and clinical characteristics of the patients, association with tuberculosis (TB) infection, number of immunosuppressive therapies, recurrences, best corrected visual acuity (BCVA) change, and ADA-related side effects were recorded. The progression rate before and after ADA was calculated based on the area involved by FAF.Sixteen eyes of 8 patients (3 female/5 male) were enrolled to the study. The median (IQR) age was 53.5 (16.5) years. Diagnosis was SC in 4, ampiginous choroiditis in 3, and TB-related serpiginous-like choroiditis in 1 patient. Peripapillary involvement was present in 10 of 16 eyes. The area involved by FAF continued to progress under ADA treatment, however the progression rate was decreased (p = 0.143).The BCVA was preserved (p = 0.772). The number of systemic and local treatments decreased with ADA (p = 0.025 and 0.019, respectively). Additionally, the number of recurrences was reduced with ADA (p = 0.002). Median (IQR) follow-up was 45(28.75) months. Two patients experienced ADA-related side effects (pulmonary TBand rash).Our findings suggest a promising role for ADA in halting the progression of SC and have implications for improving outcomes. Despite the evidence in the literature at the level of case reports, ADA can be used effectively with close monitoring for potential risks. [ABSTRACT FROM AUTHOR]

PurposeMethodsResultsConclusionTo investigate the association of clinical findings and indocyanine green angiography (ICGA) score with inflammatory markers derived from complete blood count (CBC) parameters in patients with Vogt-Koyanagi-Harada (VKH) to determine the diagnostic and predictive role.Demographic characteristics, presenting complaints, ocular findings, optical coherence tomography findings, ICGA scores and best corrected visual acuity were recorded in treatment-naive VKH patients at presentation. Patients were divided into two groups as acute stage and chronic recurrent stage. CBC parameters were noted in patients at presentation and healthy controls (HC, n = 25). Neutrophil-lymphocyte-platelet-monocyte counts, neutrophil/lymphocyte (NLR), platelet/lymphocyte (PLR), monocyte/lymphocyte and systemic immune-inflammation index (SII) were recorded. The association between these markers and clinical severity were evaluated.Thirty-two patients with VKH (23 females/9 males) with a mean age of 34.1 ± 14.6 years were included in the study. There was an increase in neutrophil count, NLR and SII in patients with VKH compared to HC (p < 0.001). The cut-off values for these three parameters were 4.37, 2.24 and 562.35, respectively. Twenty-six patients presented in the acute stage and six patients presented in the chronic recurrent stage. Choroidal thickness, early stromal hyperfluorescence and total ICGA scores were higher in patients presenting in the acute stage (p < 0.001, 0.001 and 0.025, respectively). Patients with higher disease severity at presentation were treated earlier. Early stromal vessel hyperfluorescence and choroidal vasculitis scores were correlated with decreased lymphocyte count, increased NLR, PLR and SII (p < 0.05).CBC-derived inflammatory parameters indicate that VKH is a systemic inflammation. These parameters can be used in the diagnosis and determination of disease severity of VKH. [ABSTRACT FROM AUTHOR]

To evaluate the ocular features, course, and prognosis of uveitis in the ocular sarcoidosis (OS) subgroups without previously known systemic sarcoidosis. Ninety-one eyes of 49 patients were included. Definite OS patients were classified as group 1 (n = 15), presumed OS patients as group 2 (n = 15), and probable OS patients as group 3 (n = 19). The most common presentation of OS was panuveitis in all groups. During the follow-up, bilateral ocular involvement was observed in 85.7% of the patients. The most common extraocular involvement was pulmonary involvement, which was detected in 61.2% of the patients at the time of diagnosis. Ophthalmologists should be aware that uveitis may be the first sign of systemic sarcoidosis. In all subgroups of OS, uveitis tends to be bilateral and the most common type is panuveitis. Therefore, the eye without obvious clinical findings should be carefully evaluated clinically and angiographically. [ABSTRACT FROM AUTHOR]

Purpose: To develop an algorithm for the diagnosis of Behçet's disease (BD) uveitis based on ocular findings. Methods: Following an initial survey among uveitis experts, we collected multi-center retrospective data on 211 patients with BD uveitis and 207 patients with other uveitides, and identified ocular findings with a high diagnostic odds ratio (DOR). Subsequently, we collected multi-center prospective data on 127 patients with BD uveitis and 322 controls and developed a diagnostic algorithm using Classification and Regression Tree (CART) analysis and expert opinion. Results: We identified 10 items with DOR >5. The items that provided the highest accuracy in CART analysis included superficial retinal infiltrate, signs of occlusive retinal vasculitis, and diffuse retinal capillary leakage as well as the absence of granulomatous anterior uveitis or choroiditis in patients with vitritis. Conclusion: This study provides a diagnostic tree for BD uveitis that needs to be validated in future studies. [ABSTRACT FROM AUTHOR]
