Electro-oculographic analysis of opsoclonus: its relationship to saccadic and nonsaccadic eye movements.
Opsoclonus and intention tremors of the body were seen transiently in a 20-year-old woman with postinfectious encephalopathy. Electro-oculograms showed multidirectional eye oscillations: oblique and disconjugate involuntary movements were commonly seen. The opsoclonus was triggered by both saccadic and nonsaccadic eye movements including those not concerned with visual fixation.
