What is nystagmus?

Nystagmus is continuous uncontrolled to and fro movement of the eyes. The movements may be in any direction. This means that the eyes will look like they are moving from side to side or up and down or even in circles. Most people with nystagmus have reduced vision.

There are two main types of nystagmus, one which appears in the first months of life which is called "early onset nystagmus" or "congenital nystagmus" and another which develops later in life which is usually called "acquired nystagmus".

Further information can be found on our nystagmus web page.

We also have a nystagmus leaflet, part of our Understanding series:
