[Pattern ERGs recorded with a self-made gold plated electrode in normal subjects].
PERGs were recorded with a self-made gold plated electrode in normal subjects. The latency and amplitude of b wave were 48.7 + 1.6 ms and 3.7 + 0.9 uv respectively. The amplitudes of b wave and negative after-potential from the cornea-ear lead were larger than those from the cornea-temporal or the cornea-forehead lead, but no statistically significant differences were noted among the latencies from the 3 leads. The gold plated electrode is believed suitable for recording the PERG, and placement of the reference electrode on the ipsilateral earlobe recommended.
