Gene therapy, which is the deliberate transfer of DNA for therapeutic purposes, can be defined as the in situ production of a therapeutical material within the diseased cells. The eye is an ideal target for gene therapy, as it is confined to a small space, separated by the retina-blood barrier from other organs, there are a limited number of cells present, and the endpoint can be optically monitored. Following subretinal injection, recombinant adenovirus and recombinant adeno-associated viruses successfully transduced retinal cells. Of the retinal cells, retinal pigment epithelial cells were transduced with the highest efficiency. The expression of the transgene was transient in adenovirus-injected eyes, in contrast, the expression of the transgene in adeno-associated virus-injected eyes was present throughout the 3-month examination period. These observations suggest that gene therapy with adeno-associated virus could be a suitable approach for the treatment of genetic diseases of the retinal pigment epithelium and adenoviruses for the transient regulation of gene expression in retinal pigment epithelial cells.
