—We undertook a retrospective study of all choroidal nevi with overlying neovascularization seen at Bascom Palmer Eye Institute, Miami, Fla, to determine long-term effects on vision and whether the presence of neovascularization represented increased malignant potential of the lesion.
—A computer search of patients with a coded diagnosis of both a choroidal nevus and choroidal neovascularization was performed. Cases in which the neovascularization was directly overlying the nevus were used for the study.
—The records of 23 patients followed up for a mean of 6.5 years were reviewed for visual acuity, effect of treatment, and change in the size of the choroidal lesion. Fifteen of the 23 patients had a final visual acuity in the affected eye of 20/200 or better. Five of six patients treated with laser had visual improvement of 2 or more lines. Only one of these lesions showed any growth, and this was after 17 years of no growth.
—Choroidal neovascularization associated with choroidal nevi can have profound effects on vision. Laser treatment, when indicated, is effective and may be safely performed. The clinical course of these lesions, to date, does not indicate any clinically significant malignant transformation.
