Choroidal nevus is a benign melanocytic tumour, which presents itself as a flat, dark gray-brownish pigmented lesion, occurring more commonly in the post-equatorial region, often with overlying drusen and a yellowish ring around the base (halo nevus).<\/p>\n

Multiple nevi may occur in patients with neurofibromatosis.<\/p>\n

The nevus can grow during puberty, but in adults the growth should be watched. The chance of a nevus converting into a melanoma is extremely low (1\/20,000). Features such as subretinal fluid or overlying orange pigment imply an active mass and could be an early sign of a malignant transformation of the lesion.<\/p>\n

Choroidal neovascularization membrane associated with exudation or hemorrhage may develop.<\/p>\n

The features in the fluorescein angiogram will vary depending on the degree of pigmentation. When the nevi encroaches or replaces part of the choriocapillaris, the lesions may appear hypofluorescent.<\/p>\n
