Ocular Gene Therapy with Adeno-associated Virus Vectors: Current Outlook for Patients and Researchers.

ABSTRACT: In this "Perspective", we discuss ocular gene therapy - the patient's perspective, the various strategies of gene replacement and gene editing, the place of adeno-associated virus vectors, routes of delivery to the eye and the remaining question - "why does immunity continue to limit efficacy?" Through the coordinated efforts of patients, researchers, granting agencies and industry, and after many years of pre-clinical studies, biochemical, cellular, and animal models, we are seeing clinical trials emerge for many previously untreatable heritable ocular disorders. The pathway to therapies has been led by the successful treatment of the RPE65 form of Leber congenital amaurosis with LUXTURNA TM . In some cases, immune reactions to the vectors continue to occur, limiting efficacy. The underly
