(ni-STAG-mus): Involuntary, rhythmic, side-to-side or up-and-down (oscillating) eye movements that are faster in one direction than the other.

Series of slow and saccadic (fast and large) movements of eyeball seen most obviously during rotation of head. Part of vestibulo-optic reflex that attempts to keep the retinal image steady during movement of head.

is defined as a biphasic ocular oscillation containing an abnormal slow and corrective fast phase, the latter defining the direction of the nystagmus X Y Z

The involuntary, rapid and rhythmic movement of the eyes. This movement is usually from side to side, but it can be up and down or circular. The cause is usually not known.

is a rhythmic, repetitive, oscillatory eye movement. It may occur as a result of vestibular problems, as a result of visual problems, or as a result of certain brain stem or cerebellar abnormalities. Vestibular Nystagmus is characterized by a slow migration of the eyes in the wrong direction, followed by a sudden jerking back response.

rapid involuntary oscillation of the eyes.

oscillating movements of the eye

An eye condition characterized by rapid, jerky eye movements.

Involuntary rapid movements of the eyes.

is an eye movement in which there is a biphasic oscillation of the eyes. It can be seen normally under some circumstances (such as the extremes of gaze) as well as in a number of diseases affecting the brainstem, vestibular apparatus and cerebellum X Y Z

Jerky-appearing involuntary eye movement.

rapid movement of the eyeballs.

A horizontal, vertical, rotational, or mixed involuntary oscillation of the eyeball.

involuntary movements of the eyeballs; the presence or absence of nystagmus is used to diagnose a variety of neurological and visual disorders

a constant eye jerking motion where the eye fades to one side, then jerks back

a jerking movement of the eye due to its inability to focus itself steadily on a fixed object and/or on a moving object

a rhythmic sometimes jerky movement of the eyes

a specific neurologically-caused kind of eye oscillation, That's not correct

a specific neurologically-caused kind of eye oscillation, which is not the same thing as a shaking caused by enharmonic vibration

This disorder is defined as uncontrollable eye movements that are rapid and repetitive. These movements may be horizontal, vertical, or rotary and results from abnormal functioning in the area of the brain that control eye movements. In the majority of cases, this disorder is irreversible.

Condition in which the eye oscillates repeatedly.

Involuntary, erratic eye movements.

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.

Persistent, rapid, involuntary, back and forth movements of the eyes, usually from side to side.

A rapid, repetitive, involuntary movement or rotation of the eyes. Ocular Hypertension: High ( greater than 21 mm Hg) intraocular pressure.

Involuntary oscillations of the eye

invulontary movement of the eyeball, characterized by altarnate slow and quick components resulting in a jerky unequal movement of the eye. It may be associated with diseases of the cerebellum and its central connections, the eye or the inner ear. In certain circumstances, it may also be produced as a normal phenomenon.

An involuntary bouncing or jerking of the eye caused by any number of vestibular, neurological or physiological disturbances.

Rapid rhythmic repetitious involuntary eye movements.

Periodic, rhythmic, involuntary movement of both eyeballs

uncontrolable movement of the eye Term Meaning

The jerking "to and fro" movement of the eyes that occurs when disorders affect the control of eye movement.

An oscillatory movement of the eyeballs.

Involuntary jerking of the eyes. It occurs in disorders of the part of the brain responsible for eye movements

involuntary oscillatory movements of the eyeballs in horizontal, vertical, rotatory, or mixed directions

A constant, cyclical movement of the eyeballs in any direction.

Rhythmic oscillations of the eyes back and forth. Often caused by poor or no vision early in life.

The eyes, even when they look as if they are still, are in constant motion. However, eye movements can be out of the person's control and the eyes can move from side to side or up and down. This problem is called Nystagmus.

Involuntary rapid and repetitive movement of the eyes. Go to Top

Jerky involuntary movement of the eyes.

Rapid and involuntary eye movement that is oscillating and non-chaotic. Blurred vision may result. Nystagmus typically affects infants and has a variety of causes.

involuntary rapid movement of the eyeball

persistent, rapid, involuntary movement of the eyes

jerking movement of the eyes associated with neurological disorder

rhythmic movement of the eye in a vertical, horizontal, or rotary direction

is an involuntary rhythmical flickering of the eyeball, usually up and down or side to side and sometimes-circular movements. This flickering may only manifest when looking in certain directions or it may be constant. It has been observed in albinos and in children whose corneas have lost all transparency owing to inflammation. It has also been observed in total blindness, in coal miners due to insufficient light over a long period, in certain nervous diseases such as multiple sclerosis and where there is a lesion of the internal ear.

Physical movement of the eyeballs that occurs in a rhythmic nature when the vestibular system is over-stimulated or spontaneously in certain abnormal vestibular systems.

Rapid, involuntary to-and-fro shaking movements of the eyes.

Constant, involuntary, cyclical movement of the eyeball. Movement may be in any direction. May be constant or elicited. May be due to congenital conditions, occupational, labyrinithine irritability, or neurological disease.

A specific, rhythmic motion of the eyeballs, sometimes in response to certain neurologic tests. Can result from chronic CO exposure.

Involuntary, alternating rapid and slow movements of the eyeballs.

involuntary movement of the eyeballs in unison

An involuntary, rhythmical movement of the eyeballs.

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.

Jerking of the eyes, which is usually a result of damage to the brain stem.

involuntary jerking movement of the eye in any direction

Involuntary jerky repetitive movements of the eyes when the gaze is fixed. The coarse component in non-labrynthine disease is in the direction of the lesion. Horizontal and vertical nystagmus can occur simultaneously in states of intoxication (alcohol, dilantin), or in diseases involving the vestibular connections of the brainstem, such as Wernicke's disease, multiple sclerosis, and pontine gliomas.

A rapid, involuntary movement of the eye. It is a type of tremor that people with MS may experience.

involuntary, rapid eye movements

Abnormal eye movements consisting of repetitive jerks.

Any persistent, unusual, uncontrolled movement of the eyes that make them jerk or jiggle. Often rhythmic.

Involuntary (reflex) alternating movements of the eyeballs, induced normally by active or passive head motion; induced abnormally by disease conditions in the labyrinth or CNS. Nystagmus may also be induced during certain tests (caloric, Tullio, Hennebert, etc.). See biphasic nystagmus.

Nystagmus is rapid involuntary rhythmic eye movement, with the eyes moving quickly in one direction (quick phase), and then slowly in the other (slow phase). The direction of nystagmus is defined by the direction of its quick phase (e.g. right nystagmus is due to a right moving quick phase). Nystagmus may occur in the vertical or horizontal directions, and also in a semicircular movement, and thus are called downbeat nystagmus, upbeat nystagmus, seesaw nystagmus, periodic alternating nystagmus, and pendular nystagmus.
