Influence of facial paresis on ocular vestibular-evoked myogenic potentials

Acta Oto-Laryngologica, 2013
The ocular vestibular-evoked myogenic potential (oVEMP) test with eyes up condition may help differentiate facial paresis with and without vestibular nerve deficit, while the oVEMP test with the eyes closed condition is not reliable for testing patients with facial paresis.This study investigated the influence of facial paresis on oVEMPs via the eyes ...

Ocular vestibular evoked myogenic potentials in patients with acoustic neuroma

European Archives of Oto-Rhino-Laryngology, 2012
To assess the usefulness of vestibular testing in patients with acoustic neuroma, considering two main aspects: to compare diagnostic sensitivity of the current vestibular tests, especially considering ocular vestibular evoked myogenic potentials (OVEMPs) and to identify pre-operative localization of the tumor (inferior vestibular nerve vs.

Ocular and Cervical Vestibular-Evoked Myogenic Potentials in Tumarkin Falls

Otology & Neurotology, 2012
This study applied ocular vestibular-evoked myogenic potential (oVEMP) and cervical VEMP (cVEMP) tests in Ménière's patients with Tumarkin falls to investigate the etiologic role of the saccule/utricle in the event of Tumarkin falls.Retrospective study.University hospital.Twenty unilateral definite Ménière's patients were divided into 2 age- and sex ...

Vergence increases the amplitude of lateral ocular vestibular evoked myogenic potentials

Experimental Brain Research, 2021
The angular and linear vestibulo-ocular reflex responses are greater when viewing near targets to compensate for the relatively larger translation of the eyes with respect to the target. Our aim was to measure vestibular evoked myogenic potentials using a lateral ocular electrode montage (oVEMP) with a laterally applied stimulus using a mini-shaker ...

Ocular vestibular evoked myogenic potentials in superior canal dehiscence

Journal of Neurology, Neurosurgery & Psychiatry, 2008
Patients with superior canal dehiscence (SCD) have large sound-evoked vestibular reflexes with pathologically low threshold. We wished to determine whether a recently discovered measure of the vestibulo-ocular reflex-the ocular vestibular evoked myogenic potential (OVEMP)-produced similar high-amplitude, low-threshold responses in SCD, and could ...

Ocular Vestibular Evoked Myogenic Potentials and Motion Sickness Susceptibility

Aviation, Space, and Environmental Medicine, 2012
A functional vestibular system is a prerequisite for motion sickness (MS) to occur. The otolithic organs (saccule and utricle) are currently considered to be important in the pathogenesis of MS. Recent investigations have demonstrated that the ocular vestibular evoked myogenic potentials (oVEMP) test is an objective evaluation of utricular function. To

Asymmetric Ocular Vestibular Evoked Myogenic Potentials in Pediatric Vestibular Migraine

Otology & Neurotology, 2023
Objective Although ocular vestibular evoked myogenic potentials (oVEMP) abnormalities have been associated with vestibular migraine (VM) in adults, no studies have evaluated this in pediatric patients with VM. oVEMP asymmetry with normal cervical VEMP (cVEMP) findings may be a reliable VM biomarker in adults.

The effect of amblyopia therapy on ocular vestibular evoked myogenic potentials

Clinical and Experimental Optometry
The development of vestibular-ocular reflex (VOR) is dependent on the visual input from both eyes. The ocular vestibular evoked myogenic potential (oVEMP) test provides an objective assessment of contralateral utricular function and associated VOR pathways.This study investigated the effects of amblyopia therapy on oVEMP responses in children with ...

Ocular vestibular evoked myogenic potentials in different types of amblyopia

Clinical and Experimental Optometry
The visual system plays an important role in the development of the vestibular-ocular reflex (VOR). In clinical practice, the ocular vestibular evoked myogenic potential (oVEMP) test is used to assess contralateral VOR.This study sought to compare the oVEMP in patients with anisometropic, strabismic, and mixed amblyopia using unilateral and bilateral ...

Cervical and Ocular Vestibular Evoked Myogenic Potentials Are Sensitive to Stimulus Phase

Audiology and Neurotology, 2010
Sinusoidal forces with frequencies of 100 and 500 Hz and initial positive or negative polarities were delivered to the mastoids and Fz in normal subjects. We investigated whether the cVEMPs and oVEMPs evoked were sensitive to the polarity (phase) of vibration.
