Figure 1: Fundus photograph, OCT, fluorescein angiograph, and autofluorescence images for Patient 1 (a 56-year-old man). A color fundus photograph obtained at the first visit showed an upper temporal vein occlusion in the right eye (A). The best-corrected visual acuity in his right eye was 0.3. A “cotton wool” patch was noticed in the affected area. OCT and fluorescein angiography revealed cystoid macular edema (B). Fluorescein angiography showed a petaloid-shaped hyperfluorescence at the fovea (C). Fundus autofluorescence revealed petaloid autofluorescence corresponding to a cystoid space at the fovea (D).
