The patient was a 72-year-old man without visual complaints who was found to have retinal edema in the left eye while being examined at a visit for planned refraction after cataract surgery. The visual acuity was 20/25+1 J1+ OD and 20/60-1 J1+ OS. Past medical history was remarkable for kidney cancer treated with nephrectomy in 2002 and hypertension. Ophthalmic examination was remarkable for a posterior chamber intraocular lens with a clear posterior capsule in each eye; depigmentation temporal to the fovea in the right eye; and central macular edema, inferior hard exudates, and depigmentation above the fovea in the left eye. Autofluorescence was unremarkable in both eyes. OCTs and fluorescein angiography were done.
