Vestibular Hypofunction

The body’s fastest reflex is the vestibulo-ocular reflex. The VOR holds our gaze steady on something we want to keep looking at even when our head moves. Though the VOR’s locus is the inner ear, it performs a crucial task for the eyes by maintaining clear vision; people whose inner-ear hairs have been damaged or killed by certain medications or trauma see blurry. Physical therapy retrains the VOR, mainly by exercising it.
