Choroidal nevus. (a) Amelanotic choroidal nevus with overlying RPE alterations and areas of RPE atrophy. (b) EDI OCT image shows both anterior and posterior margins of the lesion. There is gradual transition between the hyperreflective inner choroid and hyporeflective outer choroid. There is loss of choriocapillaris over the main lesion. Multifocal excrescences of the RPE are also present, suggestive of drusen.
