Abstract

Branch retinal artery occlusion (BRAO) and branch retinal vein occlusion (BRVO) rarely cause neovascular glaucoma (NVG). A 58-year-old woman with hypertension and type 2 diabetic mellitus complained of progressive visual loss in her right eye for the previous 3 months. At initial examination, visual acuity was 20 / 63 in the right eye. Angle neovascularization was observed and the intraocular pressure (IOP) was 30 mmHg in her right eye. Fundus examination and fluorescein angiography showed BRAO combined with BRVO. We immediately injected intravitreal and intracameral bevacizumab in her right eye. The next day, we performed scatter photocoagulation in the nonperfusion area. One month later, visual acuity was 20 / 20 in her right eye and the IOP was 17 mmHg with one topical antiglaucoma agent. The neovascularization had regressed completely. We report a case of unilateral NVG which was caused by BRAO with concomitant BRVO and advise close ophthalmic examination of the iris and angle in BRVO with BRAO.
