Why do some people's eyes dart back and forth?

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.

What does it mean when someone's eyes dart back and forth?

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. The movements may be very subtle, very prominent, or somewhere in between. They can be fast or slow.

Why do eyes move back and forth when thinking?

The eye movements we are discussing are called saccades. Their role in vision is to bring salient information onto the fovea. Because the saccades that accompany thinking do not seem to occur for the purpose of visual processing, we refer to them as “nonvisual” eye movements.

Why do people's eyes dart around?

When we enter a room, we make larger sweeping saccades as we gaze around. Then there are the small, involuntary eye movements we make as we walk, to compensate for the movement of our head and stabilise our view of the world. And, of course, our eyes dart around during the 'rapid eye movement' (REM) phase of sleep.

These events usually last less than 6 seconds but can happen many times per day.

Can no sleep cause nystagmus?

Sleep deprivation can manifest as neurological signs including mild nystagmus, impairment of saccadic eye movements, loss of accommodation, exophoria (ie, deviation of the eyes outward), hand tremor, ptosis of the eyelids, expressionless face, thickened speech, mispronunciations, and incorrect choice of words.

Does nystagmus run in families?

The severity of nystagmus varies, even among affected individuals within the same family. Sometimes, affected individuals will turn or tilt their head to compensate for the irregular eye movements.
