Swept-source OCT angiography identifies choroidal neovascularization arising from a choroidal nevus

Abstract

Swept-source optical coherence tomography angiography (SS-OCTA) was used to diagnose choroidal neovascularization (CNV) arising from a choroidal nevus. A 61-year-old woman initially presented with submacular hemorrhage. She was diagnosed with neovascular age-related macular degeneration (AMD) and received three injections of bevacizumab (Avastin; Genentech, South San Francisco, CA). At a follow-up visit, SS-OCTA showed that the CNV appeared to arise from an adjacent choroidal nevus. This is the first report of using SS-OCTA to diagnose CNV associated with a choroidal nevus masquerading as neovascular AMD.
