Case 9-12, Chorioretinal Scar from Previous Toxoplasmosis
A 23-year-old man had a history of toxoplasmosis in both eyes. The left eye (A) was notable for an atrophic and hyperpigmented chorioretinal scar involving the central macula. The visual acuity in this eye was 20/80.
An OCT image (B) taken through the scar displayed a complete loss of neurosensory retinal tissue consistent with an old, focal necrotizing retinitis. Increased reflectivity was observed from the retinal pigment epithelium (RPE) and choroid corresponding to epithelial hyperpigmentation and alteration of the choroidal architecture. The reflection from the choroid was fragmented due to shadowing by the hyperpigmented RPE.
