Objective: To compare ocular vestibular evoked myogenic potential (oVEMP) responses obtained with superomedial and oblique gaze positions. Methods: The oVEMP test was applied in 59 healthy subjects at superomedial, right oblique, left Stimuli were presented 110 dB nHL a frequency of 500 Hz. recorded via electrodes placed on the lower eyelids. Results: Higher N1-P1 amplitudes positions stimulated ear direction compared to position (p<0.05). asymmetry values than those Superomedial had...

Objectives: Inferior oblique muscle overaction (IOOA) is a common ocular motility disorder. Ocular Vestibular Evoked Myogenic Potentials (oVEMP) are tests that evaluate the reflex pathway between utricular macula and inferior to detect vestibular diseases. Our study of great importance as it first in literature effect on oVEMP parameters. Methods: Thirty-five patients with unilateral (IOOA group) 18 healthy volunteers without any neurological or vestibulocochlear disease were included this...
