โœฆ Synopsis


We examined temporal frequency curves by pattern visual evoked potential in 28 eyes suffering from retinitis pigmentosa (RP). The peak latency of the P100 component was 110.3 +/- 3.0 msec (S.E.), which was not significantly different from the 110.2 +/- 0.8 msec (S.E.) obtained from 60 normal controls. The P100 amplitudes of whole reversal frequencies, however, were decreased in patients with RP (p less than 0.05), especially at lower frequencies. We thought this phenomenon was useful for determining central visual function in patients with RP.

Pattern reversal visually evoked cortical potentials were recorded from 70 normal volunteers, aged from 4 to 70 years. Eleven reversal frequencies between 1 and 20 rev/sec were presented. The progressive reduction in the amplitude of the P100 component with age for lower frequency ranges was shown u
