a rapid, involuntary oscillation (usually back and forth) of the eyes that causes impaired vision It is often seen in children born with poor vision From: http: //www nystagmus org/
Involuntary horizontal, vertical, or rotary movement of the eyeballs See also vision after head injury
Continual, regular, uncontrollable movement of the eyes affecting detail vision The condition may vary and is often worse when a person is under stress or is tired; as a result vision may vary Click here for more information
Uncontrolled, involuntary rhythmic rapid eye movements which may be congenital or acquired Usually in response to movement of the head
Involuntary, rhythmic side-to-side or up-and-down eye movements in which movement to one direction is faster than movement to opposite direction See Free Eye Tests
A series of automatic, back and forth eye movements Different conditions produce this reflex A common way of producing them is by an abrupt stop followed by a series of rotations of the body The duration and regularity of postrotary nystagmus are some ofthe indicators of one aspect of vestibular system efficiency
Nystagmus is a rhythmical oscillation of the eyeball, either pendulum-like or jerky A variety of causes for nystagmus are know In space-related research, the caloric nystagmus (caused by hot or cold water in the ear), the optokinetic nystagmus (triggered by looking at a rotating dome), and the vestibular nystagmus (when a rotation of the body stops abruptly) are of special interest
small involuntary tremors of the eyeballs; when physiological nystagmus is eliminated by stabilizing the image on the retina the perception fades rapidly from fatigue of the retinal receptors
nystagmus caused by suddenly stopping the rapid rotation of the body; large slow movements of the eyeballs are in the direction opposite to the direction of rotation
nystagmus caused by the body rotating rapidly; large slow movements of the eyeballs are in the direction of rotation
