Nystagmus

Nystagmus is an involuntary, rapid and repetitive movement of the eyes. Usually the movement is side-to-side, but it can also be up and down, or even circular. The movement can vary between slow and fast, and it usually involves both eyes.

People with nystagmus may not be aware of their eye movements because what they see usually does not appear shaky to them. In order to see more clearly, they may tilt or turn their head, which helps to dampen or slow down the eye movements.

The movement of your eyes is controlled by your brain. Your eyes move reflexively to adjust for slight movement of your head.

There are two kinds of Nystagmus: Congenital and Acquired

Some Causes of Nystagmus are:

·      Heredity

·      Albinism

·      A wide range of eye disorders

·      Diseases

·      Injury to the head

·      Use of certain medications

·      Alcohol or drug use

·      Inner ear problems

Surgery on the eye muscles may be appropriate for some people with nystagmus. Improving vision with spectacles or contact lenses is an important part of treating nystagmus.
