Abstract:
Inherited retinal degenerations are a clinically and genetically heterogeneous group of conditions that have historically shared an untreatable course. In recent years, however, a wide range of therapeutic strategies have demonstrated efficacy in preclinical studies and entered clinical trials with a common goal of improving visual function for patients affected with these conditions. Gene therapy offers a particularly elegant and precise opportunity to target the causative genetic mutations underlying these monogenic diseases. The present review will provide an overview of gene therapy with particular emphasis on key clinical results to date and challenges for the future.
