目的探讨视觉眼电图各项参数与眼别、性别、年龄的关系,探索敏感判读指标,为正确判读视觉眼电图提供参考。方法用视觉眼电图(EOG)分别检测正常组和患者组。正常组包括36例30-45岁正常成人和49例5-14岁正常儿童,患者组为18例内因性前部葡萄膜炎患者。对正常组EOG的8项参数与眼别、性别及年龄进行相关性分析。按EOG不同参数对患者组进行判读,比较异常率。结果(1)正常成人EOG各项参数左右眼间、男女性别间均无差异,正常成人组光峰电位(LPP)、暗谷电位(DTP)、基值电位(BP)、电位差值(PD)四项参数高于儿童组。(2)LPP+ Arden比及DTP+Arden比两种联合方式的异常率明显高于单项参数的异常率。结论(1)成人EOG电位幅值性参数高于儿童。(2)联合多项参数判读EOG能提高阳性率,提升EOG的临床实用价值。
Objective To explore the relationship between the various parameters of visual electrooculography (EOG) and eyes, sex and age, and to explore the sensitive reading indexes to provide a reference for correctly interpreting visual electro-oculography. Methods Visual and electrooculogram (EOG) were used to detect normal group and patient group respectively. The normal group consisted of 36 normal adults aged 30-45 years and 49 normal children aged 5-14 years, with 18 patients with endogenous anterior uveitis. Eight parameters of EOG in normal group were compared with those of eyes, gender and age. According to different parameters of EOG patient group interpretation, abnormal rate. Results (1) There were no significant differences in the parameters of normal adult EOG between the left and right eyes and between male and female. The values of LPP, DTP, BP, PD Four parameters were higher than children’s group. (2) The anomalous rates of LPP + Arden ratio and DTP + Arden ratio were significantly higher than those of single parameter. Conclusion (1) Adult EOG amplitude amplitude parameters higher than children. (2) The combination of multiple parameters to interpret EOG can improve the positive rate and enhance the clinical value of EOG.
