choroidal dystrophy, central areolar type 2

A disorder (OMIM:613105) that affects the posterior pole of the eye. Early lesions consist of a non-specific patch of granular hyperpigmentation at the fovea; the characteristic feature of the disease—a sharply-demarcated area of macular atrophy of the pigment epithelium and choriocapillaris—occurs several decades after onset.
Molecular pathology
Defects of PRPH2, which encodes peripherin 2, cause central areolar choroidal dystrophy type 2.
