Among the genetic diseases of vision, retinitis pigmentosa (alone or in combination with systemic afflictions like Usher syndrome, Kearns-Sayre syndrome) deserves special interest because it can be autosomal dominant, autosomal recessive, and X-linked. Leber's hereditary optic neuropathy, the first mitochondrial disease to be defined at the molecular level, manifests at mitochondrial DNA position 11778, but 10 other mutations have recently been found, all residing within mitochondrial DNA-encoded respiratory chain polypeptides. The analysis of Leber's optic neuropathy mutations has provided new important insight into the phenotypic expression of mitochondrial DNA mutations. Some rarer hereditary diseases of vision such as Cone dystrophy, dominant optic atrophy, Leber's congenital amaurosis, Stargardt maculopathy, and choroideremia are discussed.

The aim of this review is to provide a comprehensive summary of current gene therapy clinical trials for monogenic and optic nerve disorders.The number of genes for which gene-based therapies are being developed is growing. At the time of writing this review gene-based clinical trials have been registered for Leber congenital amaurosis 2 (LCA2), retinitis pigmentosa 38, Usher syndrome 1B, Stargardt disease, choroideremia, achromatopsia, Leber hereditary optic neuropathy (LHON) and X-linked retinoschisis. Apart from RPE65 gene therapy for LCA2 and MT-ND4 for LHON which has reached phase III, all other trials are in investigation phase I and II, i.e. testing the efficacy and safety.Because of the relatively easy accessibility of the retina and its ease of visualization which allows monitoring of efficacy, gene-based therapies for inherited retinal disorders represent a very promising treatment option. With the development of novel therapeutic approaches, the importance of establishing not only clinical but also molecular genetic diagnosis is obvious.Key words: gene therapy, monogenic retinal diseases, optic nerve atrophy, mitochondrial disease.
