Image of the Month (IOTM) is a collection of interesting clinical cases with high quality images for all relevant imaging modalities (ex: color fundus, OCT, OCTA, FAF, FA, En Face, Red-free, choroidal vasculography (CVG), anterior imaging) and other clinical results if relevant (ex: visual field plots). Each case is submitted by an eye care professional using one of Topcon’s industry-leading OCT devices.

Case 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 hypo-autofluorescence in the nevus. Enface OCT (Image C) revealed a well-circumscribed flat lesion.
