Nystagmus Definition & Overview


Nystagmus is a type of involuntary movement of the eyes. It is usually side-to-side, but sometimes is up and down or in a circular fashion (rotatory nystagmus). The movement varies between slow and fast and usually involves both eyes. Nystagmus most often occurs in infancy, but it can also be acquired later in life. In infancy, it tends to develop between six weeks and three months of age.

Nystagmus can reduce vision and can also be associated with other conditions that limit vision, such as strabismus (an eye turned in, out, up, or down). Nystagmus affects people in many different ways. It is important to see a doctor so that treatment for the condition and any associated disorders can be obtained to improve vision. Sometimes it is accompanied by dizziness, which indicates an inner ear or a central nervous system problem.

More importantly, nystagmus maybe a sign of a more serious underlying problem.
