title: Hamartoma of the retinal pigment epithelium.
abstract: A 9-year-old boy had a unilateral ocular lesion characterized by a broadly elevated mass at the level of the retinal pigment epithelium. The mass showed hyperpigmented borders, overlying retinal constracture, retinal vessel tortuosity, and vitreous condensations. Electrophysiologic testing revealed an abnormal electrooculogram.
