[Pattern ERG and VECP following optic neuritis in childhood].

Pattern ERGs and pattern VECPs were recorded in 12 patients who had suffered from optic neuritis in childhood. When each individual's eyes were compared, the eye with the longer P100-latency in pattern VECP was found to have the smaller amplitude in pattern ERG. The latency differences correlated with the amplitude differences. These findings confirm that after optic neuritis the amplitude of pattern ERG is reduced.
