Does blindness affect ocular vestibular evoked myogenic potentials?

Ali Bayram et al. Am J Otolaryngol. 2018 May-Jun.

Abstract

Objective: The aim of the present study was to investigate the influence of blindness on ocular vestibular evoked myogenic potentials (oVEMP) responses.

Methods: Thirty-one subjects with unilateral blindness (UB group) and 25 age and sex-matched healthy subjects (control group) were recruited for the present study. The oVEMP responses including latency, amplitude and amplitude asymmetry ratio (AR) were measured and compared between the blind side, the contralateral eye of the UB group and the control subjects.

Results: Ocular VEMP recordings were obtained from 29 of 31 patients (93.5%) for the blind side of the UB group. There was no significant difference in terms of latency, amplitude and AR value between the blind side and the contralateral eye of the UB group and the control subjects.

Conclusion: Clear oVEMP recordings can be elicited as long as the eyeball and extraocular muscles are preserved in a blind eye.

Keywords: Blindness; Ocular vestibular evoked myogenic potentials.
