Spasmus Nutans
Definition Spasmus nutans is a specific type of pendular nystagmus of infancy accompanied by head bobbing and occasionally by abnormal position of the neck.
Overview, Causes, & Risk Factors
Spasmus nutans involves a triad of symptoms which includes horizontal, vertical, or pendular nystagmus (fine, rapid jerking of the eyes back and forth, and from side to side), head nodding, and head tilting.
Most cases begin between age 4 months and 1 year. It usually goes away by itself in several months to years. Less commonly it may be associated with other causative conditions. Rarely, symptoms like those of spasmus nutans may be produced by tumors in the optic chiasm or third ventricle of the brain.
