Case 8-34. Recurrent Choroidal Neovascularization
An 83-year-old woman was referred for evaluation of recurrent choroidal neovascularization in her left eye. She had received laser photocoagulation in this eye two months earlier; however, her visual acuity had not improved from 20/ 125, Slit-lamp biomicroscopy (A) showed a small pigmented lesion in the central macula with surrounding subretinal fluid and macular edema, A well-defined annul us of hyper fluorescence was evident on fluorescein angiography (B). The annulus increased in intensity in later frames with some late leakage-
A well-defined region of retinal thickening was noted on the OCT scan (C), The reflection from the retinal pigment epithelium and choriocapillaris was diminished in the area of the lesion, and moderate backscatter signa l was observed subretinallv consistent with a neovascular membrane (arrows). A region of minimal backscattering consistent with subretinal serous fluid accumulation was evident temporal to the lesion. The reflectivity from the subretinal fluid increased in the area just anterior to the membrane.
