Case 8-31. Choroidal Neovascularization
A 77-year-old man with age-related macular degeneration had a visual acuity of counting fingers at six inches in his left eye. Slit-lamp examination (A) showed a fi-brovascular pigment epithelial detachment in the fovea with surrounding subretinai fluid and hemorrhage, Alacy region of hyperfluorescence within a region of hypofluorescence was seen during the arteriovenous phase of the fluorescein angiogram (13) with late leakage consistent with a choroidal neovascular membrane,
A horizontal OCT scan (C) through the macula revealed a well-defined region of abnormal discontinuities in the retinal pigment epithelium and patchy reflections from the choriocapillaris, consistent with a neovascular membrane. The neurosensory retina above the membrane appeared thickened, and reduced optical reflectivity in this area suggested intraretinal fluid accumulation.
