Amelanotic choroidal nevi
Abstract
A review of 373 patients with presumed choroidal nevi revealed 19 (5.1%) to have largely or totally amelanotic nevi. All patients but one with amelanotic nevi were white, and all were 48 years of age or older. Each lesion was located posterior to the equator, had a mean diameter of 3.2 mm, and was less than or equal to 1 mm in elevation. Intravenous fluorescein angiography most often disclosed early and late hyperfluorescence, corresponding to the amelanotic areas of the nevus. No lesions were observed to grow during a mean 14-month follow-up period. The differential diagnosis of amelanotic nevi of the choroid is discussed and includes amelanotic malignant melanoma, cavernous hemangioma of the choroid, metastatic cancer to the choroid, posterior scleritis, choroidal osteoma, and hypopigmented congenital hypertrophy of the retinal pigment epithelium.
