Clinical and electrooculographic study of two cases of ocular myoclonus

Ocular myoclonus is an abnormal movement of the eyes present in the clinical picture of rhythmic myoclonia of the soft palate-pharynx-larynx-diaphragm. Two patients are presented in whom an ocular myoclonus was observed and in whom clinical and neurophysiologic studies were made, emphasizing the electro-oculogram and the sleep recording. The difference with opsoclonus was estimated, especially in relationship with the angular velocity of the ocular movements.
