What causes nystagmus?
Nystagmus is caused by a miscommunication between the eye and the brain and affects the way our brains interpret movement signals from the eye. Nystagmus is typically caused by brain injuries and is a result of brain damage. This eye condition may be referred to as “dancing eyes” because of the repetitive eye movement.
Does nystagmus go away?
In most cases, acquired nystagmus goes away after the cause has been treated. In rare cases, it can be caused by a serious medical condition such as a stroke, cataracts, an inner ear disorder, or a head injury.
What are the signs and symptoms of nystagmus?
- sensitivity to light.
- difficulty seeing in the dark.
- vision problems.
- holding the head in a turned or tilted position.
- the feeling that the world is shaking.
Is nystagmus a serious condition?
Congenital or inherited nystagmus is not typically associated with serious medical conditions. However, acquired nystagmus may be a sign of a serious medical condition, including severe head trauma, toxicity, stroke, inflammatory diseases, or other conditions that affect the brain.

What does nystagmus feel like?
Oscillopsia, or the illusory sensation that the stationary visual world is moving, is the major symptom experienced by patients with nystagmus.

Attacks typically last 2 hours only, but usually the next day or two there will be some nystagmus also. In about 85% of the cases, the nystagmus is horizontal with the fast component directed towards the healthy hearing ear, suggesting a vestibular paresis on the side to which the slow phases are directed.
Is nystagmus an emergency?
Although it is not typically an emergency, pendular nystagmus should be assessed promptly. Depending on associated symptoms, the doctor may order tests such as a brain MRI or blood work to rule out a potentially dangerous cause such as stroke.
What is nystagmus indicative of?
Nystagmus is most commonly caused by a neurological problem that is present at birth or develops in early childhood. Acquired nystagmus, which occurs later in life, can be the symptom of another condition or disease, such as stroke, multiple sclerosis or trauma.
What part of the brain causes nystagmus?

- Being passed down from your parents.
- Other eye issues, like cataracts or strabismus.

- Albinism (lack of skin pigment)
- Inner ear problems.

Nystagmus can occur normally, such as when tracking a visual pattern. Nystagmus may also be abnormal, usually in situations where one would want the eyes to be still, but they are in motion. Vertigo (a sensation of spinning), is often accompanied by nystagmus.
What doctor treats nystagmus?
Surgery may improve vision. Nystagmus may be caused by congenital diseases of the eye. Although this is rare, an eye doctor (ophthalmologist) should evaluate any child with nystagmus to check for eye disease. The most common cause of acquired nystagmus is certain drugs or medicines.

How is nystagmus diagnosed?
- eye-movement recordings (to confirm the type of nystagmus and see details of the eye movements)
- an ear exam.
- a neurological exam.
- tests to get images of the brain, including computerized tomography (CT) and magnetic resonance imaging (MRI)
Can u drive with nystagmus?
You do not need to tell DVLA if you have nystagmus, as long as you meet the standards of vision for driving. You may still need to tell DVLA about other medical conditions.

What does it mean to have jerk 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.
How many types of nystagmus are there in the world?
