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.
