Abstract
|
|
|
|
The cerebellum plays an important role in eye movement control, especially modulation of saccade, pursuit and vestibuloocular reflex. Three separate parts of the cerebellum are thought to be involved in the principal oculomotor syndromes: the syndrome of the flocculus and paraflocculus, the syndrome of the nodulus and ventral uvula, and the syndrome of the dorsal vermis and underlying caudal fastigial nuclei. Cerebellar infarction can show abnormal ocular findings according to arteries that supply these regions. Common central vestibular abnormalities in a cerebellar stroke were gaze evoked nystagmus, rebound nystagmus, impaired smooth pursuit and optokinetic response, and impaired fixation-suppression of vestibular ocular reflex.
