Nystagmus is rapid involuntary movement of the eyes which often seriously reduces vision. Few people with nystagmus can drive and most encounter some difficulties in every day life, education and employment. Nystagmus affects around 1 in 1,000 people.
Anyone can get nystagmus. Every year hundreds of children are born to parents with no family history of nystagmus as well as to families where the condition already exists, Nystagmus which occurs in infancy has many names including Congenital Nystagmus, Infantile Nystagmus and Early Onset Nystagmus. In addition, every year hundreds of adults develop (acquire) nystagmus due to accidents or illnesses such as stroke or multiple sclerosis. This is generally known as Acquired Nystagmus.
