目的：建立适用于本视觉电生理检查室的脑电皮肤电极记录视网膜电图正常值指标，以利于将其用于配合度低的患者。
方法：选取2015-03/09来我科检查后诊断为正常者30例51眼，分别采用角膜接触镜电极和皮肤电极记录视网膜电图，对检查结果进行比较分析。
结果：两种电极检查结果差异都有统计学意义(P<0.05)。幅值上皮肤电极结果均明显低于角膜接触镜电极，其占角膜接触镜电极幅值的比值为20%～30%； 但潜伏期较角膜接触镜电极稍提前，其占角膜电极记录结果的比值为95%～96%。
结论：将脑电皮肤电极用于配合度低的患者可以提供有价值的视网膜功能信息。

[Abstract]
AIM:To establish a suitable normative reference value for electroretinogram(ERG)testing using electroencephalogram(EEG)skin electrodes.
METHODS: The ERG was recorded in 51 eyes(30 people)who were normal after ophthalmologic examination in our department from March to September 2015 using skin electrodes and contact lens electrodes. The recorded result was reviewed and analyzed, and all the testings were recorded by the routine program.
RESULTS: The 95% confidential interval, mean or median of values was defined in amplitudes and latencies of various responses. All the amplitudes results of skin electrodes were significantly lower than those of the contact lens electrodes and the ratio(amplitudes of skin electrodes to those of the contact lens electrodes)was 20% to 30%. The latencies results of skin electrodes were significantly shorter than those of contact lens electrodes and the ratio was 95% to 96%.
CONCLUSION: The EEG skin electrode used for patients with low compliance may provide valuable information of retinal function.
