Transient opsoclonus with thalamic hemorrhage.
Opsoclonus, a rare and dramatic saccadic eye movement disorder, was seen in three patients following thalamic hemorrhage. The occurrence of this presumed cerebellar-system disorder in association with pupillary and oculomotor signs of pretectal dysfunction suggests that upper brainstem damage may facilitate the release of spontaneous saccades.
