The otolith organs, saccule and utricle, sense linear acceleration in the vertical and horizontal planes Any damage to the otoliths or their central connections impairs the body’s equilibrium and visual stability. These patients often complain of the feeling of chronic unsteadiness, rocking or floating.
However, until recently, there was no method of measuring the damage to the otolith organs.
Subjective Visual Vertical (SVV) testing is an easy tool to detect otolithic dysfunction. Vestibular evoked myogenic potential (VEMP) testing is used to quantify otolithic input. The cervical ( c-VEMP) and ocular (o-VEMP) have been used to test the function of the utricle and saccule.
Otolith disorders are treated by long term vestibular rehabilitation aimed at otolith stimulation.
