Clinical signs of visual-vestibular interaction.

Clinical signs of visual-vestibular interaction.

Visual suppression of vestibulo-ocular reflexes (induced vestibular nystagmus) differs between normal subjects and patients with various neurological disorders. Abnormalities of VOR suppression were associated consistently with abnormalities of the visual and/or vesitibular oculomotor reflexes and in particular with abnormal smooth pursuit eye movements in the direction of abnormal suppression....

Visual - vestibular Interaction : Basic Science to Clinical Relevance

Introduction The vestibular system, which provides a signal of head motion to the brain, mediates functions of gaze and postural stabilisation via vestibular-ocular (VOR) and vestibular-spinal reflexes. The vestibular system is also key in generating sensations of selfmotion and spatial orientation required for navigation in the environment. The vestibular system influences these reflex and per...

Vestibular disease: anatomy, physiology, and clinical signs.

The vestibular system is responsible for keeping an animal oriented with respect to gravity. It is a sensory system that maintains the position of the eyes, body, and limbs in reference to the position of the head. Proper interpretation of neurologic deficits and precise neuroanatomic localization are essential to diagnose and prognosticate the underlying disorder. Neurologic examination can co...

Visual-vestibular interaction with telescopic spectacles.

Vestibularly and visually driven eye movements interact to compensate for head movements to maintain the necessary retinal image stability for clear vision. The wearing of highly magnifying telescopic spectacles requires that such compensatory visual-vestibular interaction operate in a quantitative regime much more demanding than that normally encountered. We employed electro-oculography to inv...
