a Color photograph of the left disc and macula shows pale disc edema, marked irregularity of the retinal vasculature (arrows) and hemorrhages inferior and nasal to the optic disc. b The arteriovenous-phase fluorescein angiogram of the left disc and macula shows an optic disc staining, as well as extensive non-perfusion of the retinal vasculature and venous congestion. Of note, the blot hemorrhages inferior to the optic disc cause irregular hypofluorescent blockage
