Purpose: To compare ocular vestibular evoked myogenic potential (oVEMP) responses obtained with superomedial and oblique gaze positions. Material and Methods: The oVEMP test was applied in 59 healthy subjects at superomedial, right oblique, and left oblique gaze positions. Stimuli were presented at 110 dB nHL with a frequency of 500 Hz. oVEMP responses were recorded via electrodes placed on the lower eyelids. Results: Higher N1-P1 amplitudes were obtained in oblique gaze positions in the stimulated ear direction compared to the superomedial position (p<0.05). The asymmetry values obtained in the superomedial gaze position were lower than those obtained in oblique gaze positions (p<0.05). Superomedial and oblique gaze positions had no effect on the N1, P1, and N1-P1 latencies of the waves obtained from the right ear, left ear, and both ears (p>0.05). Conclusion: Superomedial and oblique gaze positions affect oVEMP waves. In patients in whom vestibular hypofunction is suspected, it is recommended to control oVEMP responses in oblique gaze positions as well as in superomedial gaze positions in the evaluation of the residual vestibular functions.
