Frequency dependence of the ocular-recorded vestibular evoked myogenic potentials (oVEMP) and their significance for the diagnosis of endolymphatic hydrops

Introduction The detection of oVEMP with the potentials n10 and p15 is predominantly specific for the contralateral utriclular function. A shift in the amplitude maximum from a stimulus frequency of 0.5 kHz to 4 kHz is said to indicate an increase in pressure in the endolymphatic space.
