The cumulative results from genetic research and treatment protocols tested on cell and animal models have improved our understanding of pathobiology of inherited and degen- erative eye diseases, and have lead to the development of a broad range of potential strategies to treat these conditions. In this special issue of the Journal of Ophthalmology, a series of articles provide a review of various areas of current eye research and clinical practice. A retinal degeneration phenotype is observed in several nonsyndromic and syndromic disorders, which are genet- ically and phenotypically heterogeneous. Usher syndrome, the commonest cause of deaf-blindness, is characterized by retinal degeneration, hearing loss, and, in some cases, abnormal vestibular function. Usher syndrome has been classified into three forms based on the age of onset, severity of retinal degeneration, and hearing loss. So far, nine genes associated with Usher syndrome have been identified. In this issue
