Spontaneous, non rhythmic, multidirectional and chaotic movements of the eyes are termed as opsoclonus or ataxic conjugate movements. The eyes appear to be in a state of agitation with burst of conjugate movements of varying amplitude in varying directions. The eyes move in any linear or rotating direction at a rate of up to 10 times per second. Most common cause of opsoclonus in children is encephalitis although it may be the first sign of neuroblastoma.
