Case 8-6. Pigmented Chorioretinal Scar
A 52-year-old man with degenerative myopia experienced a decline in the vision in his right eye two years prior to evaluation. At that time, a choroidal neovascular lesion was diagnosed and treatment was not performed. On the present examination (A), the visual acuity in his right eye was 20/125, and there was a pigmented chorioretinal lesion in the center of the macula. A region of chorioretinal atrophy was noted immediately inferior to the fovea.
A horizontal section (B) disclosed a highly reflective lesion just beneath the fovea, A diffuse increase in choroidal reflectivity temporal and nasal to the lesion was noted consistent with slight pigmentary atrophy. The retina also appeared diffusely thinned. The reflections from the retinal pigment epithelium and choriocapillaris within the lesion shadowed the backscatter signal from the deeper choroid below the lesion consistent with hyperpigmenta-tion and fibrosis,
