Eye movements are any shift of position of the eye in its orbit. There are many different kinds of eye movements, which are defined in the next section titled ‘Classes of eye movements. ‘ Eye movements determine what information reaches our retina, visual cortex, and most important, higher cortical centers.
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.
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.

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.
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.
The good news Nystagmus is not painful and does not lead to total blindness. Vision tends to improve until it stabilises around the age of five or six. Giving children plenty of stimulation in the early years does seem to help them make best use of the vision they have.
Generally, nystagmus is a symptom of another eye or medical problem. Fatigue and stress can make nystagmus worse. However, the exact cause is often unknown.
