Foveal neovascularization in proliferative diabetic retinopathy: Characterization with OCTA
Foveal neovascularization (FNV) is a rare clinical finding in conditions with vascular compromise, leading to ischemia of the retina. We present a case of proliferative diabetic retinopathy (PDR) with FNV, where optical coherence tomography angiography (OCTA) confirmed the architecture, extent, activity, and origin of a hemorrhage-like clump at the fovea. Digital Florescein Angiography (DFA) showed PDR (both eyes), but intra-retina microvascular abnormalities (IrMAs) or FNV could not be differentiated at the site of leak in right eye fovea. OCTA confirmed a FNV breaching the internal limiting membrane (ILM), protruding into vitreous, and determined its origin from superficial vascular plexus (SVC). Also, segmentation revealed flow voids in choriocapillaris slab, suggesting choroidal ischemia.
