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

โฆ Synopsis
Development of visual evoked cortical potential waveforms and the spatial frequency characteristics of the pattern reversal stimuli were studied in children from 7 weeks to 15 years of age. All subjects were born at term. Waveforms were found to change rapidly during the first several months after the birth, from single slow positive peaks to negativepositive-negative complex.
Spatial frequency characteristics in N2 latencies were observed to develop rather slowly up to school age. Long-term development of pattern vision in children was suggested.

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 control
Forty-one eyes in 21 cases of ethambutol optic neuropathy were investigated for the pattern visual evoked cortical potential (VECP) and the pattern electroretinogram (ERG). In 21 of the eyes the disappearance VECP responses were not detectable. In the other 20 eyes the peak latency and amplitude of
We describe three patients with central areolar choroidal dystrophy whose electroretinograms (ERGs) and pattern visually evoked cortical potentials (VECPs) confirmed their macular dysfunction. Visual fields measured by Goldmann perimetry showed central relative scotomata corresponding to a dystrophi
Twenty-one eyes of thirteen patients suffering from optic neuritis were examined with the Octopus automated perimeter and pattern visually evoked cortical potentials. All eyes had visual acuity of 0.2 or better. Visual field examination was measured by program 31 or 33, which tests the central 30-de
