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. 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. There was no statistical significance (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. 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.
分析三种不同眼位下眼前庭诱发肌源性电位的特征，并探索眼前庭诱发肌源性电位（oVEMP）的合适眼位。选取2017年12月至2018年5月期间接受oVEMP测试的15例眩晕患者（30耳）作为患者组，其中男性7例，女性8例，平均年龄（51±13）岁。另招募22例（44耳）健康青年作为对照组，其中男性10例，女性12例，平均年龄（23±5）岁。分别在以下三种眼位测量oVEMPs：直上30度（上中位）、右上45度（右上位）和左上45度（左上位）。采用SPSS 23.0统计软件分析oVEMP引出率、潜伏期、波幅及双耳波幅不对称率。对照组、患者组及总体受试者中，三种眼位的oVEMP引出率、潜伏期、波幅及不对称率差异均无统计学意义（P>0.05）。三种眼位均可用于临床检测oVEMP，引出率及波形特征无差异。当其中一个眼位难以注视或不易获得重合曲线时，也可采用另外两个眼位获取理想的oVEMP曲线。
