This page has a summary of information about nystagmus and links to some articles about nystagmus.
Experts agree that nystagmus affects about one in a thousand people.
One survey in Oxfordshire identified one in every 670 children by the age of two as having nystagmus. The flautist James Galway, our patron, is probably the best known person in Britain with nystagmus. Nystagmus may be inherited or result from a sensory problem. In some cases it occurs for no known reason. It can also develop in later life, sometimes as a result of an accident or a range of illnesses, especially those affecting the motor system.
