A 46-YEAR-OLD man sought treatment after 3 months of gradually worsening vision in the left eye. He was otherwise in good health. Best-corrected visual acuity at initial examination was 20/20 OD and 20/60 OS. Anterior segment examination results were unremarkable. Fundus examination results were remarkable for juxtafoveal telangiectatic vessels in the right eye, with a sharp foveal reflex. The left eye was remarkable for juxtafoveal telangiectatic retinal vessels and cystoid macular edema. Fluorescein angiography showed hyperfluorescent telangiectatic vessels in the early stages (Figure 1) that leaked in the late stages in both eyes, with cystoid dye accumulation in the late phases in the left eye (Figure 2). Bilateral acquired parafoveal telangiectasis complicated by cystoid macular edema was diagnosed in the left eye.
