Vestibulo-ocular reflex

From WikiMD.com - Food, Medicine & Wellness Encyclopedia

(Redirected from Oculocephalic reflex)

Vestibulo-ocular reflex (VOR) is a neurological reflex that stabilizes gaze during head movement by producing an eye movement in the direction opposite to head movement. This reflex is essential for maintaining a stable visual field and preventing blurred vision or dizziness during head movement.

Mechanism[edit | edit source]

The VOR is mediated by the vestibular system, which detects changes in head position and movement. The semicircular canals of the inner ear detect rotational head movements, while the otolith organs detect linear head movements. These sensory organs send signals to the vestibular nuclei in the brainstem, which in turn send signals to the extraocular muscles to move the eyes in the opposite direction of the head movement.

Clinical significance[edit | edit source]

Abnormalities in the VOR can lead to a variety of symptoms, including vertigo, nystagmus, and oscillopsia. These symptoms can be caused by a variety of conditions, including vestibular neuritis, Meniere's disease, and vestibular schwannoma. The VOR can be assessed clinically using the head impulse test, caloric reflex test, and rotational chair test.

Research[edit | edit source]

Research into the VOR has provided insights into the neural mechanisms underlying motor control, sensory integration, and adaptation. This research has potential applications in the development of treatments for balance disorders and rehabilitation strategies for individuals with vestibular dysfunction.
