Neuro-ophthalmic manifestations of cerebellar disease

The cerebellum is responsible for refining ocular movements, thereby guaranteeing the best possible visual acuity and clarity despite changes in body or head positions or movement of the object of interest. The cerebellum is involved in the control of all eye movements, in their real-time, immediate modulation, and in their long-term adaptive calibration. The flocculus-paraflocculus complex and the caudal vermis (nodulus and uvula) together constitute the vestibulocerebellum. Lesions affecting these different regions give rise to 3 principal clinical cerebellar syndromes. This article discusses the various neuro-ophthalmic manifestations of various cerebellar disorders, as well as some therapeutic options for oscillopsia.
