Retinal Neovascularization Secondary to Proliferative Diabetic Retinopathy Characterized by Spectral Domain Optical Coherence Tomography. Retinal neovascularization is the hallmark of the proliferative stage of diabetic retinopathy and is a major cause of vision loss in diabetes. This chapter discusses our current knowledge regarding the mechanisms underlying retinal neovascularization in diabetic retinopathy, with a focus on the critical role played by vascular endothelial growth factor (VEGF).
