Abnormal1
  • Abnormal eye movements may be a result of early abnormal development or a sign of underlying neurological or neuromuscular disease. (bvsalud.org)
Nystagmus2
  • Since slight head movement is present all the time, VOR is necessary for stabilizing vision: people with an impaired reflex find it difficult to read using print, because the eyes do not stabilise during small head tremors, and also because damage to reflex can cause nystagmus. (wikipedia.org)
  • You may have a small amount of uncontrolled eye movement ( nystagmus ) when looking to an extreme left or right position. (ucsfbenioffchildrens.org)
Stimuli1

  • The reflex acts to stabilize images on the retinas of the eye during head movement. (wikipedia.org)
  • The vestibulo-ocular reflex is driven by signals arising from the vestibular system of the inner ear. (wikipedia.org)

Gaze4
  • both eyes' movements into the 9 diagnostic positions of gaze are assessed. (aao.org)
  • Gaze is held steadily on a location by producing eye movements in the direction opposite that of head movement. (wikipedia.org)
  • During gaze anchoring, we found that neurons in the reach region of the posterior parietal cortex can inhibit neuronal firing in the parietal saccade region to suppress eye movements and improve reach accuracy. (nature.com)
  • [ 3 ] Versions are movements of both eyes in the same direction (eg, right gaze in which both eyes move to the right). (medscape.com)
Muscles2
  • Another option is to get injections of botulinum toxin into the muscles that control your eye movement. (healthline.com)
  • CVS is caused by long periods of computer use, which results in fatigue to both the ocular muscles that are responsible for visual accommodation and muscles involved in eye movement. (cdc.gov)
