目的了解婴幼儿患者视网膜电图测试的特点及其临床应用意义.方法根据国际临床视觉电生理学会ERG标准化方案,应用日本光电公司生产的Neuropaek MEB-2200K电生理仪对出生40d至6周岁以下的婴幼儿患者共314例(621只眼)进行测试.结果将314例(621只眼)患者根据临床诊断分组.各种病变出现不同比例的ERG改变,异常眼中锥杆细胞ERG异常和熄灭型最为多见,其次为视锥细胞ERG降低,杆锥细胞ERG异常也占较高比例,其他类型较少.其中视网膜病变患者以熄灭型ERG为主,其次为锥杆或杆锥细胞ERG异常,眼球震颤婴幼儿主要表现为锥杆ERG异常,其次为视锥细胞ERG下降和杆锥细胞ERG异常.约半数屈光不正患者和弱视婴幼儿ERG正常,异常者中以视锥ERG下降多见.结论大部分婴幼儿患者的ERG出现异常.因此,继续推广视觉电生理检查的技术和相关知识对于婴幼儿眼病的正确诊断具有重要的意义.

Objective To find the characteristics and clinical application of electroretinogram(ERG)in infant patients.Method Three hundred and fourteen cases (621 eyes)of infant patients (aged 40 day to 72months)were tested with Nenropack MEB-2200K system according to the ERG standard of ISCEV.ResultsThe patients were divided into groups according to the clinical diagnosis.The ERG abnormal rates weredifferent in various diseases.The cone-rod ERG decreases and extinguish were the most,followed by the coneERG and red-cone ERG decrease.In patients with retinopathies, most of ERG were extinguish type, followedby cone-rod or rod-cone decreases.In patients with nystagmus,most of ERG were cone-rod ERG decreasetype, followed by cone ERG decrease and rod-cone ERG decreases.About half of patients with ametropia andamblyopia showed normal ERG.Conclusion Abnormal ERG appeared in most of the infant patients.Thepopularity of visual electrophysiological technique and associated knowledge is still very important for thecorrect diagnosis of infant eye diseases.
