IOTM: Melanotic Choroidal Nevus

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

69 year old male with a suspicious extramacular melanotic choroidal nevus measuring 1.65mm thick, overlying RPE atrophy, subretinal fluid and 20/20 vision. No growth demonstrated over 2 years of follow up and no response to anti-VEGF therapy. 9 mm vertical Topcon Triton Swept-Source OCT B-scan (Figure D) penetrates the full thickness of the nevus. Spaide Fundus Autofluorescence imaging (Figure A) helps demarcate the nevus and areas of subretinal fl uid as also revealed on OCT. Stable clinical picture.
