Since the first reports describing the injection of recombinant adeno-associated viral (AAV) vectors in the murine eye, the advancement of the field has been enormous resulting in the correction of several animal models of retinal diseases. The recent development of "pseudotyped" AAV vectors with transduction characteristics that best fit the correction of specific retinal disease phenotypes and of sophisticated systems for tight regulation of gene expression expands on the potentiality of this delivery system for the eye.
