What is Nystagmus?

Nystagmus is an involuntary eye movement usually from side to side, but sometimes the eyes swing up and down or even in a circular movement. Nystagmus usually results in some degree of visual loss. The degree and direction of eye movement, amount of visual loss and resulting impairment varies greatly from person to person.
