The introduction of optical coherence tomography angiography (OCT-A) has generated interest in evaluating vascular dysfunctions in the optic nerve head for the diagnosis and monitoring of glaucoma. The purpose of this study is to compare perfusion of the optic disc between normal subjects and subjects with glaucoma using OCT-A in order to detect changes in perfusion of the optic disc. Using the OCT-A AngioVue® system, an examination was performed on 40 eyes of 40 patients (20 with glaucoma and 20 healthy controls). Total radial peripapillary flow density (4.5×4.5mm) was measured at different levels of segmentation. The study demonstrated that the peripapillary vascular flow of OCT-A and exploration of the optic nerve head was better in the normal eyes compared to glaucoma patients. This review provides a comprehensive summary of the most important current and potential applications of OCT-A in glaucoma.

Purpose: The purpose of this study was to investigate the contribution and natural progression of ABCA4 deep intronic variants (DIVs) among a Chinese Stargardt disease (STGD) cohort.
Methods: For unsolved STGD probands, DIVs in ABCA4 were detected by next-generation sequencing, and splicing effects were evaluated by in silico tools and validated through minigene experiments. Comprehensive ocular examinations, especially fundus changes, were carried out and analyzed.

Purpose: Bietti crystalline dystrophy (BCD) is a rare retinal dystrophy characterized by progressive visual impairment. This study aimed to evaluate changes in retinal and choroidal vessels and blood flow in BCD patients using swept-source optical coherence tomography angiography (SS-OCTA) and to investigate potential parameters associated with visual function.
Methods: This cross-sectional study included 166 eyes from 86 clinically diagnosed BCD patients, classified into three disease stages based on Yuzawa's classification.

Purpose: We report a case of Eales disease in Inuit and reflect on advances in telemedicine and treatment of retinal disease since the first report of Eales' disease in Greenlandic Inuit was published.
Patients And Methods: A 41-year-old Inuit female complaining of blurred vision was referred to our eye department. There had been no sign of diabetic retinopathy during diabetic eye screening and the patient had been treated for tuberculosis in 2010.
