Intermittent see-saw eye movements. Report of a patient in coma after hyperextension head injury.

For 24 hours after an automobile accident, a 19-year-old comatose man exhibited spontaneous, intermittent, see-saw, rotatory, and downward eye movements with synchronous lid elevation. These unusual movements, which appear most closely related to nonpendular see-saw nystagmus and atypical ocular bobbing, probably resulted from the severe pontomedullary tegmental damage found at autopsy.
