Gaze-evoked nystagmus (GEN) is a drift of the eye which is only present for certain directions of gaze away from straight ahead. It is the most common form of nystagmus encountered in clinical practice.
What neurological conditions cause nystagmus?
Causes of nystagmus can include:
- Stroke.
- Head trauma.
- Central nervous system diseases, such as multiple sclerosis and brain tumors.
- Certain medications, such as anti-epilepsy drugs.
- Various eye disorders, such as cataracts, strabismus, nearsightedness, farsightedness, and astigmatism.
What is seesaw nystagmus?
Seesaw nystagmus is a sequence of abnormal eye movements in which one eye moves up as the other moves down. In addition to the alternating opposed vertical movements, there is rotation (torsion) of the eyes.
Does nystagmus affect hand eye coordination?
A simulated prosthetic vision study in a visually impaired subject found that nystagmus adversely affected performance on a hand–eye coordination task when phosphenes moved in parity with the eyes.
Do brain tumors cause nystagmus?
Pediatric brain tumors can distort, damage, and destroy portions of the brain involved in both the afferent and efferent vision pathways. This interruption of normal visual pathways can lead to permanent vision loss or other morbidities such as strabismus and nystagmus.
What does a person with nystagmus see?
If you have nystagmus, your eyes move or “wobble” constantly. This can be in a side to side, an up and down, or a circular motion, or a combination of these. This uncontrolled movement can affect how clearly you can see. Most people with nystagmus have reduced vision.
What is torsional nystagmus?
Torsional (rotary) nystagmus refers to a rotary movement of the globe about its visual axis. Nystagmus that is purely torsional, or rotary, is rare and indicative of a disorder of the central vestibular system. Torsional nystagmus is typically accentuated on lateral gaze.
What is Latent nystagmus?
Latent nystagmus is a binocular horizontal oscillation that becomesapparent when 1 eye is covered. First described by Faucon in 1872,8 latent nystagmus develops when congenital esotropiaprecludes frontal binocular vision early in infancy.
Does nystagmus mean brain damage?
Although there are several areas of the brain that control eye movement, nystagmus is most often associated with damage to the cerebellum or brainstem. Damage to the inner ear can also lead to nystagmus.
Does anxiety cause nystagmus?
Nystagmus. According to the American Optometric Association, nystagmus is generally triggered by stress and overall fatigue.
What were your first signs of a brain tumor?

Can people with nystagmus drive a car?
Mobility training can help. Few people with nystagmus are legally able to drive a car.
What is the difference between oscillopsia and nystagmus?
Oscillopsia usually occurs as a result of conditions that affect eye movement or alter how parts of the eye, inner ear, and brain stabilize images and maintain balance. It often links to types of nystagmus, which is a condition that causes abnormal or involuntary eye movement.
What is Upbeating nystagmus?
Upbeating nystagmus describes an eye condition in which the eyes drift downward and make upward corrective movements (beats). Here we are mainly discussing upbeating nystagmus that occurs in persons who are sitting upright, and that have their eyes in the center (primary position).
What is dissociated nystagmus?
Dissociated nystagmus refers to the two eyes having nystagmus with the same direction but with differing amplitudes. Disconjugate nystagmus occurs when the two eyes have different directions of oscillation, one example of which is sea-saw nystagmus.
What kind of trauma causes nystagmus?
Nystagmus refers to a secondary effect of head injury that causes the eyes to make rapid, uncontrolled movements. It usually occurs after cerebellar damage.
How do you calm nystagmus?

Can an eye test show a brain tumour?
A regular, routine eye test can sometimes detect eye problems that indicate the presence of a brain tumour before any symptoms become obvious. An eye test is particularly good at identifying any swelling of the optic disc (a condition called papilloedema) and can also identify when there is pressure on the optic nerve.
Can you have a brain tumor for years without knowing?
Because different areas of the brain control different functions of the body, where the tumor lies affects the symptoms you get. Some tumors have no symptoms until they’re large and then cause a serious, rapid decline in health. Other tumors may have symptoms that develop slowly.

Is nystagmus a symptom of MS?
In some people with MS, the nerve pathways that control the movement of their eyes can be affected. As a result their eyes may not move smoothly, or the two eyes may be out of alignment. The two most common eye movement problems in MS are double vision (diplopia) and involuntary eye movements (nystagmus).
