BACKGROUND

35 year-old male referred for choroidal nevus in the right eye. BCVA was 20/20 and the patient was asymptomatic. Examination of the right eye revealed a 2 disc diameter pigmented choroidal nevus temporal to the macula. Swept-Source OCT (Image A) demonstrated a flat lesion with backscattering and overlying RPE elevation suggestive of drusen. Fundus autofluorescence (Image B) revealed central hypoautofluorescence in the nevus. Enface OCT (Image C) revealed a well-circumscribed flat lesion.
