Large druse-like lesions on the surface of choroidal nevi

Three patients had choroidal nevi with a single, large, overlying, hypopigmented lesion. In one case, this lesion was observed to enlarge for seven years, although the nevus, itself, did not. All of the hypopigmented lesions showed mild hyperfluorescence early in the fluorescein angiogram and intense staining in the later phases. These lesions were probably large drusen that developed on the surface of the nevi.
