Thirty-two patients with presumed choroidal nevi were examined and photographed in both white and green light. Twenty-one lesions disappeared or became markedly attenuated when viewed with green light. The remaining 11 lesions did not disappear when viewed with green light. Many of these nevi demonstrated visual field defects and fluorescein angiographic abnormalities. The clinical applications of green light ophthalmoscopy and photography are discussed.
