A Revıew Artıcle: Cerebellum And Eyesıght

Abstract

The cerebellum plays a significant role in the maintenance of equilibrium and the coordination of head and eye movements. The cerebellum receives extensive information from visual, somesthetic, vestibular and auditory sensory systems, as well as from motor and nonmotor areas of the cerebral cortex. The cerebellum was more active during independent rather than coordinated eye and hand tracking. Performance when tracking with the hand alone was worse than in the coordinated eye and hand condition. Cerebellum was significantly activated in coordinated eye–hand tracking compared to isolated eye and hand movements. Patients with cerebellar disease, eye movements, limb movements, gait and speech all may be affected. Bulbar muscles may also be affected, numerous disturbances of oculomotor activity, including nystagmus. In cerebellar disease decreased tone in postural muscles, Hypotonia in occulomotor muscles results in difficulty in maintaining the gaze. Studies investigating the relationship between the cerebellum and eyesight were revised in this manuscript.
