It may only last seconds, or may be permanent. There are two types of nystagmus. In pendular nystagmus, the eye motion is like a pendulum swinging back and forth. Jerk nystagmus, the more common type, is characterized by eyes that drift slowly in one direction and then jerk back the other way.
Doctors may notice nystagmus in a person being evaluated for dizziness, vertigo and other balance problems affecting the inner ear. Oscillopsia, or the illusory sensation that the stationary visual world is moving, is the major symptom experienced by patients with nystagmus. Nystagmus is diagnosed by an ophthalmologist.
They will examine the inside of your eyes and test your vision. Your ophthalmologist will also look for other eye problems that may be related to nystagmus. One way to see nystagmus is to spin a person around for about 30 seconds, stop and then have them try to stare at an object. If they have nystagmus, their eyes will first move slowly in one direction, then move rapidly in the opposite direction.
Treating nystagmus depends on the cause. People born with nystagmus cannot be cured of this condition. However, they may benefit from glasses or contact lenses. These do not fix the nystagmus, but having clearer vision can help slow the eye movements.
Rarely, surgery may be done to reposition eye muscles that move the eyes. This keeps the head from needing to turn as far to keep the eyes from moving.
However, surgery does not correct or cure nystagmus. It just allows someone to keep their head in a more comfortable position to limit eye movement. Sometimes, acquired nystagmus can go away. This happens if the condition that causes the nystagmus is treated.
That can include treating a medical problem or stopping drug or alcohol use. About Foundation Museum of the Eye.
