About

Dr. Narain is a board certified ophthalmologist and fellowship trained vitreoretinal specialist. At South Bay Retina he has pioneered new approaches to managing several chronic ocular conditions. His practice focuses on diseases of the posterior segment which include diabetic retinopathy, macular degeneration, uveitis, as well as inherited retinal diseases and conditions involving the optic nerve such as optic neuritis, glaucoma, and other optic neuropathies.

Dr. Narain utilizes advanced technologies such as wide-field retinal imaging (Optos), high-resolution OCT, electrophysiology, and microperimetry. By employing these tools, we are able to determine the relative contribution of optic nerve and retinal disease to visual function. This enables earlier recognition of ocular disease and toxicities from systemic drugs that can affect the retina and optic nerve.
