a The right fundus, showing an ischemic change at the posterior pole with foveal sparing as well as retinal hemorrhages and white patches along the superotemporal arcade. Choroidal hypopigmentation is visible in the left fundus. b An optical coherence tomography image showing thickening and opacification of the retinal layers corresponding to the ischemic area. c On fundus angiography (FA), a nonperfused area is seen superior to the macula because of the coexistence of branch retinal vein and artery occlusion. FA of the right eye shows a significant filling delay of the branches of the superotemporal retinal artery with a corresponding ischemic area (23.1 s). Sludging of the retinal artery is apparent and the retinal vein branches are tortuous and dilated (45.5 s). Capillary non-perfusion in the circulation of the superotemporal vein is observed. The perfusion defect is still present with the absence of superotemporal retinal artery branches (355.7 s). Neovascularization is not observed
