PURPOSE: To assess the spectrum of perivenular ischemia in eyes with retinal vascular obstruction (typically central or hemicentral retinal vein obstruction) using en face optical coherence tomography (OCT). DESIGN: Retrospective observational case series. METHODS: Eyes with recent retinal vascular occlusion illustrating paracentral acute middle maculopathy (PAMM) in a perivenular fern-like pattern with en face OCT were evaluated in this study...

PURPOSE: To evaluate changes in macular choroidal thickness in eyes with ischemic and nonischemic diabetic maculopathy. METHODS: Cross-sectional study of enhanced depth imaging optical coherence tomography of patients with diabetes. The diabetic eyes were divided into 3 groups: 1) eyes with no diabetic retinopathy (NDR); 2) those with diabetic retinopathy without macular ischemia (DR/MI-); and 3) those with diabetic retinopathy and macular ischemia (DR/MI+). RESULTS: This analysis included 261 eyes of 160 patients...

PURPOSE: To describe a highly recognizable and reproducible retinal phenotype associated with a specific BEST1 mutation-p.Ala243Val. METHODS: Retrospective review of consecutive cases where genetic testing has identified p.Ala243Val BEST1 as the cause of disease. Electronic patient records were used to extract demographic, as well as functional and anatomical data. These data were compared with those observed with the most common BEST1 genotype, p.Arg218Cys. RESULTS: Eight individuals (six families) were identified with the p...

The aim of the English NHS Diabetic Eye Screening Programme is to reduce the risk of sight loss amongst people with diabetes by the prompt identification and effective treatment if necessary of sight-threatening diabetic retinopathy, at the appropriate stage during the disease process. In order to achieve the delivery of evidence-based, population-based screening programmes, it was recognised that certain key components were required. It is necessary to identify the eligible population in order to deliver the programme to the maximum number of people with diabetes...

PURPOSE: To evaluate the clinical characteristics of a patient with primary open-angle glaucoma in whom macular retinoschisis resolved completely after trabeculectomy consistently lowered intraocular pressure (IOP). METHODS: A single case report. RESULTS: We report a case of retinoschisis involving the macula in a patient with primary open-angle glaucoma in the absence of myopic maculopathy, optic nerve anomaly, or x-linked retinoschisis. The patient's glaucoma was associated with progressive visual field loss in the setting of IOP fluctuations related to posture...

Myopic traction maculopathy (MTM) can cause vision disabilities in highly myopic eyes. This retrospective case series investigated the clinical outcomes of posterior scleral contraction (PSC) using genipin-cross-linked sclera as the material to treat MTM in highly myopic eyes. In total, 32 eyes from 29 highly myopic patients who underwent PSC for MTM were recruited. The changes in best-corrected visual acuity (BCVA) and axial length were evaluated, macular reattachment and macular hole (MH) closure was assessed by optical coherence tomography, and complications were evaluated...

The authors present the first case of paracentral acute middle maculopathy as a manifestation of primary antiphospholipid syndrome (APS) with multimodal imaging, including optical coherence tomography angiography (OCTA). The association between APS and ophthalmic sequela is well-known. Recent advances in multimodal imaging, specifically OCTA, allow for better characterization of the mechanism and extent by which retinal arterial thrombosis can cause vision loss. Using advanced imaging modalities, the authors provide a comprehensive assessment of retinal ischemia, which showed not only localized capillary occlusion, but also ischemia of the deep retinal capillary plexus...

Recent studies have changed the management of hydroxychloroquine retinopathy. This editorial outlines a new standard. Estimate dose by real weight, staying below 5 mg/kg. Asian patients may show initial damage outside the parafovea. Renal disease, maculopathy, and tamoxifen are major risk factors. Proper screening allows long usage and avoids bull's eye retinopathy.

Purpose: The purpose of this study was to classify exudative maculopathy by the presence of pachyvessels on en face swept-source optical coherence tomography (SSOCT). Methods: Consecutive patients with signs of exudative maculopathy underwent SSOCT, fluorescein and indocyanine green angiography (ICGA), ultra-widefield fundus color photography, and autofluorescence examinations. Images were analyzed in a masked fashion by two sets of four examiners in different sessions: (1) the presence of pachyvessels in en face OCT and (2) features of exudative maculopathy in conventional imaging modalities...

A 6-year-old boy with a complaint of blurred vision for two months was referred to our clinic. His visual acuity was 20/32 in the right eye and 20/20 in the left eye. Optical coherence tomography (OCT) revealed optic disc pit maculopathy in the right eye. The patient was followed for 6 months without any treatment. At the end of the 6-month period, the patient's visual acuity was 20/20 in both eyes. The OCT imaging showed spontaneous regression of the optic disc pit maculopathy. In this case report, it is concluded that in children, spontaneous regression of the optic pit maculopathy with full recovery of visual acuity is possible...

PURPOSE: Macular optical coherence tomography (OCT) analysis can be used for quantitative measures of optic nerve atrophy at a location far from the optic nerve head. This recently led to the finding of microcystic macular edema (MME), that is vacuolar inclusions in the macular inner nuclear layer, in some glaucoma patients. The involvement of individual retinal layers is yet unclear in glaucoma. In this study we systematically investigated glaucoma-induced changes in macular layers to evaluate whether glaucoma-associated damage extends beyond the macular ganglion cell layer...

PURPOSE: To report an unusual case of bilateral spontaneous scleral perforations. METHODS: A 34-year-old woman presented with bilateral conjunctival blebs and decreased vision in both eyes. There was no history of ocular trauma or surgery and no previous ophthalmic or systemic conditions that may have contributed to the scleral perforations. RESULTS: Best-corrected visual acuity was 20/40 in both eyes and intraocular pressures were 6 mm Hg in the right and 5 mm Hg in the left...

PURPOSE: To evaluate quantitatively the choroidal vascularity in polypoidal choroidal vasculopathy (PCV) and neovascular age-related macular degeneration (AMD) patients compared to healthy controls. METHODS: All eyes underwent swept source optical coherence tomography (OCT), and choroidal images were binarized into blood vessels lumen and stroma. The choroidal vascular index (CVI) was defined as the ratio of luminal area (LA) over total choroidal area of the subfoveal region with a width of 1500 μm...

AIM: To assess the prevalence, causes, and risk factors for blindness and visual impairment among elderly (≥60 years of age) Chinese people in a metropolitan area of Shanghai, China. METHODS: Random cluster sampling was conducted to identify participants among residents ≥60 years of age living in the Xietu Block, Xuhui District, Shanghai, China. Presenting visual acuity (PVA) and best-corrected visual acuity (BCVA) were checked by the Early Treatment Diabetic Retinopathy Study (ETDRS) visual chart...

The clinical presentation and optical coherence tomography findings in a patient with maternally inherited diabetes and deafness (MIDD) are presented to highlight the presence of macular cystoid spaces in some patients with this disease. Typically, patients with MIDD demonstrate progression of a pigmentary maculopathy into areas of geographic macular atrophy. At the time of initial visit, the 30-year-old patient had large macular cystoid changes in addition to retinal pigmentary changes in both eyes. The cystoid changes responded to treatment with systemic immunosuppression and a topical carbonic anhydrase inhibitor (CAI), recurred when treated with topical CAI monotherapy, and finally resolved after an intravitreal triamcinolone acetonide injection...

Age-related macular degeneration (AMD) is the leading cause of blindness in developed countries. It is a complex disease with both genetic and environmental risk factors. To improve clinical management of this condition, it is important to develop risk assessment and prevention strategies for environmental influences, and establish a more effective treatment approach. The aim of the present study was to investigate age-related maculopathy susceptibility protein 2 (ARMS2) gene sequences among Turkish patients with exudative AMD...
