Breaking the ocular barrier through nano-lipid carriers to treat intraocular diseases

The human eye is a special organ. Its defense mechanisms protect it from invading microbes and harmful molecules. Treatment of different eye diseases often shows poor results due to the presence of these barriers. Nano lipid carriers have the capability to overcome these anatomical and physiological barriers effectively. It can also deliver the payload to the posterior eye. These non-toxic, biocompatible carriers significantly increase the ocular bioavailability of the drug. This review highlights the important ocular barriers and the way how nano lipid carriers overcome the tough ocular barriers.
