Retinal Neovascularization–Simulating Retinal Capillary Reperfusion in Branch Retinal Vein Occlusion, Imaged by Wide-Field Optical Coherence Tomography Angiography
Retinal neovascularization is a complication of retinal vascular diseases, such as diabetic retinopathy, retinopathy of prematurity, and retinal vein occlusion. Anti–vascular endothelial growth factor therapy or laser photocoagulation arrests proliferative retinopathy after neovascularization; however, substantial reperfusion has sometimes been reported. 1 - 3 We report a case of branch retinal vein occlusion manifesting with retinal nonperfusion, covered by retinal neovascularization and appearing as retinal capillary reperfusion. In this case, optical coherence tomography angiography (OCTA) showed distinct neovascularization on the vitreoretinal surface, although there was minimal leakage from the neovascularized area on fluorescein angiography (FA) images.
