What Is Nystagmus?

The rapid, involuntary, rhythmic eye movements which occur normally during and after head rotation and sometimes with dizziness are called nystagmus.

These are normal eye movements which occur any time someone rotates his/her head in a horizontal direction.

View the short videos below for a demonstration of horizontal nystagmus and circular/torsional nystagmus.

Nystagmus

Horizontal Nystagmus

This eye movement would occur if this person were turning the head to the left. This video shows horizontal nystagmus: normal eye movements which occur any time someone rotates his/her head in a horizontal direction.

Circular/Torsional Nystagmus

Circular/Torsional Nystagmus

This eye movement can occur with an inner ear problem called positional vertigo.
