Understanding the causes of human visual defects

Much of the work of the retinal dystrophy group has consisted of identifying and studying the proteins which, when defective, give rise to a series of Mendelian diseases affecting the retina. These conditions include retinitis pigmentosa, cone-rod dystrophy and Leber congenital amaurosis, as well as many rarer conditions and syndromes involving defects of the retina and other body systems. We also have a research interest in ageing macular dystrophy (AMD), a retinal condition with complex causes including an inherited predisposition. In AMD we seek both to identify further contributory genetic factors and also to understand the genetic contribution to response to treatment with anti-VEGF therapy. In addition in our research we increasingly seek to roll out our findings into diagnostic tests for patients, in collaboration with the Yorkshire Regional Genetics Service.
