Nystagmus is a medical condition in which the eyes move involuntarily, often shaking back and forth.
These involuntary movements may be horizontal, vertical, or sometimes even rotational.
People with nystagmus due to eye problems have abnormal vision, and this decreased visual ability causes the eyes to shake.
What does nystagmus feel like?
You may feel like your eyes have a mind of their own. They move up and down, side to side, or in a circle. This is called nystagmus or “dancing eyes.” It’s a condition where you can’t control your eye movements.
What causes sudden onset nystagmus?
Most commonly spontaneous nystagmus is caused by a vestibular imbalance. Vestibular nystagmus is typically inhibited by visual fixation and also typically follows Alexander’s law (it becomes greater on gaze in direction of the fast phases).
Does nystagmus go away?
This keeps the head from needing to turn as far to keep the eyes from moving. However, surgery does not correct or cure nystagmus. Sometimes, acquired nystagmus can go away. This happens if the condition that causes the nystagmus is treated.
How common is nystagmus?
Nystagmus is the most common issue causing visual impairment in children, and it affects approximately 1 in 1,000 people. Certain types are more common in one sex over the other, but both men and women can be affected. This condition is a complex eye condition that causes involuntary eye movements.
