Nystagmus is an eye condition characterized by rapid, jerking eye movements. It does not always cause any noticeable symptoms, but it can be associated with issues such as dizziness and vision problems. A number of different neurological illnesses can cause nystagmus.
Typically, nystagmus is detected during a physical examination that involves an eye evaluation. It may be an early sign of a neurological condition, such as multiple sclerosis MS , or it can develop as an already established neurological illness progresses. Most of the time, medical or surgical management of the underlying cause is also necessary. Nystagmus typically affects both eyes, but rarely it can affect just one eye. The jerking movements are not usually present all the time, and nystagmus is often more noticeable when you are looking to one side or the other.
In severe cases, eye jerking can be present all the time, even when you are looking straight ahead not to the side. Nystagmus looks like rapid, rhythmic, horizontal side to side motion of the eyes. Vertical up and down or rotary moving in a circle nystagmus can occur as well, but these patterns are not common.

Which treatment is best for your nystagmus depends on the root cause of your condition. If your nystagmus is caused by another underlying condition, then treating that underlying condition should treat your nystagmus as well.
Once your nystagmus has been diagnosed, your optometrist or ophthalmologist will suggest an appropriate treatment. Congenital nystagmus cannot be treated, but it may be managed using glasses or contact lenses, or by ensuring your workspace is well lit.
This form of nystagmus will typically disappear as your child grows, but more severe cases may require surgery to reposition the muscles responsible for eye movement. Acquired nystagmus may be treated using a variety of methods. Which method is right for you depends on the root cause of your condition.
