The sensitivity of transient, pattern-reversal visual evoked potentials in the detection of early compressive lesions of the chiasm is controversial in the literature. There have been claims that the technique is capable of detecting an abnormality in the absence of any demonstrable visual field los
30 eye-healthy subjects were being examined, with their pupils reacting, mydriatic or miotic. Their pattern reversal visual evoked cortical potentials (PRVECP's) were recorded under steady-state conditions. Test conditions allowed establishing a statistically significant influence of pupil size on t
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
The effects of a luminance-unbalanced pattern onset-offset mode of stimulation on electroretinograms and visual evoked cortical potentials were investigated. With the use of originally devised software, only offset luminance was varied from 14.7 to 62.3 cd/m 2. A vertical grating pattern (1.5 c/deg,
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 t
