Diabetic retinopathy is a complication in diabetes which affects the eyes by damaging the blood vessels of retina. The nanotechnology enhances the bioavailability and permeability of drug in the retina as it can help to cross the barriers of eye like cornea, conjunctiva and blood retinal barriers (BRBs). Nanotech-nology ("nanotech") is manipulation of matter on an atomic, molecular, and supramolecular scale. It is consequently conjoint to see the plural form "nanotechnologies" as well as "Nano scale technologies" to rise to the expansive assortment of research and solicitations whose conjoint peculiarity is size. Because of the variability of potential capitulations (containing industrial and military), executives have endowed billions of dough in nanotechnology exploration.

Keywords: Nanofibers, electrospining, electrostatic forces, drug-polymer interactions, posterior anatomy of eye, dosing frequencies.
