In the UK, Usher syndrome is found in about 10,000 people. It was first described by the German ophthalmologist Albrecht von Graefe in 1858, while the Scottish ophthalmologist Charles Usher provided more detail about it in 1914. The condition is also referred to as deafness-retinitis pigmentosa syndrome, dystrophia retinae pigmentosa-dysostosis syndrome and Graefe-Usher syndrome.
