Abstract:
Objective:To analyze the characteristics of the ocular vestibular evoked myogenic potential on three different eye positions and to explore the appropriate eye position for oVEMP.Methods:15 patients (30 ears) with vertigo who underwent oVEMP test from December 2017 to May 2018 were selected as the patient group, including seven males and eight females, with an average age of (51±13) years. Another 22 (44 ears) healthy young people were recruited into the control group, including 10 males and 12 females, with an average age of (23±5) years. oVEMPs were measured on the following three eye positions respectively: 30 degrees straight up(upper median position),45 degrees upper right(upper right position), and 45 degrees upper left(upper left position). oVEMP elicitation rate, oVEMP latencies, amplitudes and interaural amplitude asymmetry ratio were analyzed by SPSS 23.0 statistical software.Results:There was no statistical significance ( P>0.05) in the oVEMP elicitation rate, oVEMP latency, amplitude and asymmetry ratio on the three eye positions among the control group, the patient group and the overall subjects. Conclusions:The three eye positions can be used to detect oVEMP in clinic. There is no difference in the extraction rate and waveform characteristics. When one of the eye positions is difficult to gaze or not easy to obtain the coincidence curve, the other two can be used to obtain the ideal oVEMP curves as well.
