Ocular gene therapy involves the introduction of an exogenous gene product to a host's cellular and genetic machinery for endogenous production of a desired gene product. The eye represents an ideal target organ due to its easy visibility and accessibility, and several trials have demonstrated proof-of-principle safety and efficacy in a subtype of Leber's congenital amaurosis. There are numerous ongoing clinical trials exploring gene therapy in other retinal diseases. In autosomal recessively inherited retinal degenerations, the introduced gene product replaces a known genetically deficient gene product and provides restoration of function. In other disease states, such as neovascular age-related macular degeneration, the delivered gene product modulates existing proteins within a cell, such as vascular endothelial growth factor, for a desired therapeutic effect. This latter approach may have broader applications in other diseases such as diabetes and other retinal vascular diseases that are as yet unrealized. This review summarizes the current state of clinical research in ocular gene therapy focusing on those diseases in which the technology has reached clinical trials.
