目的　定量分析正常成人眼震电图 (ENG)的特点及其与年龄、性别的关系 ,旨在为临床诊断提供可靠依据。方法　 1 80名 2 0～ 79岁正常成人 ,其中男 88名 ,女 92名 ,按年龄分成 6组 ,每 1 0年一个年龄组 ,每组 30名。进行ENG系列试验 ,包括扫视试验、平稳跟踪试验、视动试验、水平凝视试验、自发眼震试验及摇头试验。结果　扫视试验中的延迟时间、跟踪试验中的增益值、失真度及视动试验中的增益值等主要参数 ,各年龄组有明显的不同 (P <0 0 5)。随着年龄的增加 ,延迟时间呈逐渐延长趋势 [由 (1 80 55± 2 2 39)ms增至 (2 1 3 58± 31 30 )ms,r =0 33] ;跟踪试验的增益值逐渐减小(r=- 0 37) ,失真度逐渐加大 (r=0 41 ) ;视动试验的增益值也呈下降趋势 (r =- 0 42 )。但不受性别影响 (P >0 2 )。所有个体在水平凝视、自发及摇头眼震试验中均未见眼震。结论　扫视、跟踪及视动试验的主要参数受年龄影响 ,与性别无关。针对不同年龄组的患者 ,应选择相应的诊断标准 Objective To quantitatively analyze the characteristics of normal adult electrogastrogram (ENG) and its relationship with age and gender, and to provide a reliable basis for clinical diagnosis. Methods One hundred and twenty normal adults aged 20-79 years, including 88 males and 92 females, were divided into 6 groups according to their age, and each group was aged 30 years, with 30 in each group. ENG series of tests, including the glaucoma test, smooth follow-up test, visual acuity test, horizontal gaze test, spontaneous nystagmus test and shaking head test. Results The main parameters such as the delay time in the saccade test, the gain value in the follow-up test, the degree of distortion and the gain value in the visual acuity test were significantly different among all age groups (P <0.05). With the increase of age, the delay time gradually extended [from (1 80 55 ± 2 2 39) ms to (2 1 3 58 ± 31 30) ms, r = 0 33]. The gain of tracking test gradually decreased (R = - 0 37), the degree of distortion gradually increased (r = 0 41), and the gain of visual acuity test also showed a decreasing trend (r = - 0 42). But not by gender (P> 0 2). All individuals showed no nystagmus in horizontal gaze, spontaneous and shaken nystagmus test. Conclusions The main parameters of glaucoma, follow-up and visual acuity tests are affected by age and have nothing to do with gender. Patients of different age groups should choose the appropriate diagnostic criteria
