Choroidal Nevus-Associated Neovascular Membrane Demonstrated by OCT Angiography

Abstract

We present a case of choroidal nevus, complicated by a choroidal neovascular membrane (CNV) that was detected by OCT angiography. Choroidal nevi are relatively common intraocular tumors. The presence of subretinal and intraretinal fluids can indicate that a CNV has occurred as a complication, warranting prompt management. However, subretinal and intraretinal fluids are also documented in nevi without CNV. OCT angiography may be of great help in determining whether those fluids are associated or not with a CNV, therefore guiding therapy.

Keywords: Choroidal neovascular membrane; Choroidal nevus; OCT angiography; Swept-source OCT.

Swept-source OCT B-scan. This averaged picture at the fovea reveals disorganization of the outer retinal layers above the nevus as well as subretinal fluid. The borders of the nevus can be precisely delineated.

OCT angiography. Clinical examination and B-scan OCT cannot rule out the presence of a CNV. OCT angiography demonstrates a vascular lesion characterized by branching capillaries anastomosing into larger vessels and surrounded by a hypointense halo.

Fluorescein angiography reveals a classic CNV within the nevus.
