Hereditary retinal diseases and age-related macular degeneration are diseases of the posterior eye segment, or, to be precise, the so-called photoreceptor cells in the retina; the task of which is to convert light into nerve impulses in the phototransduction cascade.
Today there are approximately 150,000 blind and about 500,000 visually impaired people in Germany, many of them suffering from these hereditary diseases. The number of people in Germany suffering from age-related macular degeneration amounts to approximately two to three million with a strong upward trend. In Western industrial nations it is the main cause of blindness in people over 50 years of age.
