| definition |
Definition: Nystagmus is a rhythmic regular oscillation of the eyes. It may consist of alternating phases of a slow drift in one direction with a corrective quick "jerk" in the opposite direction, or of slow, sinusoidal, "pendular" oscillations to and fro.
This can occur due to problems in the vestibular system, or it can have a neurological cause. And it an occur when a patient is intoxicated with certain medication, drugs or alcohol.
In the clinical summaries of the NBB, the type of nystagmus was most often NOT described. It mostly will be reported in cases with cerebellar ataxia, but sometimes it can be reported without being clear whether it is of a central or peripheral origin. Therefore, it was not possible to determine/deduce the origin of the nystagmus. We have decided to score all types of nystagmus in this parameter.
