Detailed explanation-1: -Nystagmus is a term to describe fast, uncontrollable movements of the eyes that may be: Side to side (horizontal nystagmus) Up and down (vertical nystagmus) Rotary (rotary or torsional nystagmus)
Detailed explanation-2: -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.
Detailed explanation-3: -Is nystagmus a serious condition? Nystagmus itself isn’t considered dangerous. But it may be associated with serious health conditions, especially those affecting the brain, such as stroke, brain tumor, toxicity, head trauma and inflammatory diseases.
Detailed explanation-4: -Nystagmus is the medical term to describe involuntary eye movements. The eyes may move vertically, horizontally, in circles, or erratically in different directions. Nystagmus affects about 1 in every 1, 000 people. The speed of the uncontrollable eye movements can vary, but they tend to happen in both eyes.
