The vestibulo-ocular reflex (VOR) is a reflex eye movement that stabilizes images on the retina during head movements. It causes the eyes to move in the opposite direction of head movement, preserving the image at the center of the visual field. The VOR is stimulated by the vestibular system in the inner ear, which contains motion sensors that detect rotational head movements. When the head moves, the vestibular system activates nerves that control the extraocular muscles to move the eyes in the opposite direction, keeping images stable on the retina.

1. Vestibulo-Ocular Reflex
Asad Iqbal

2.  VESTIBULO OCCULAR REFLEX
 It’s conjugate ocular movement opposite
to head movement and it’s stimulated by
vestibular system

3.  When camera is moving the image will be
blurre and why not with your eyes when
you move head..? That’s VOR mechanism

4.  VOR is reflex where Activation of
vestibular system causes eye movements
 This Reflex function stabilize image on
retina
 During head movements producing eyes
movements in opposite direction to head
movement thus preservering(orginal
state) on the central visual field

5.  Vestibular apartus has sensory system
(semicircular canals) which is located in
inner layer of ear which can detect the
rotational movement
 Whenever head move the motion sensor
activited and vestibular stimulate the
nerves which control extra ocular muscle.

6.  E.g if head is moving right 30 degree so
eye should move 30 degree left to focus
the image on fovea

7.  HEAD THRUST
 We give a target to patient to fix eye and
we move the patient head to check VOR
where eyes will be moving opposite
direction to fix the image on fovea.
