To determine whether binocular summation in visual evoked cortical potential (VEP) is present in patients who have significantly different P100 peak latencies in their two eyes.Twelve patients with unilateral optic neuritis (ON) and 11 normal controls were studied.

Latency measurement improvement of P100 complex in visual evoked potentials by FMH filters
IEEE Transactions on Biomedical Engineering, 1995The ensemble average of Pattern Shift Visual Evoked Potentials (PSVEP) signals is seriously affected by random latency variations encountered in each individual sweep which is modeled as a continuous signal with linear segments and well-shaped triangular peaks. This effect is causing the smoothed peaks of the averaged PSVEP waveforms.

Comparison of latency of P100 wave in children demonstrating some pathological disorders
Acta Ophthalmologica, 2012AbstractPurpose A goal of the present paper was an assessment of usefulness of latency of P100 wave in describing few pathological disorders in children. The study group comprised 268 children, including 68 with cytomegaly (CM), 59 with myelomeningocele (MM) , 69 with purulent meningitis(PM) and 73 with Down’s syndrome (DS). The control group consisted

The aim of this study was to determine the range of normal values of the latency of the P100 component of the VEP from a control population. Weighted least squares polynomial regression analysis showed that a quadratic curve best described the relationship between age and latency and separate curves, along with normal ranges, are presented for males ...

Background & Objectives: Myopia or short-sightedness is rising globally, particularly among children and young adults with increased screen exposure. Visual evoked potentials (VEPs), measuring latencies and amplitudes, provide an objective assessment of visual pathway.

Introduction The visual evoked potentials (VEP s) is an important diagnostic tool used by neurophysiologist, ophthalmologist, neurologists and neurosurgeons as many neurological disorders present with visual abnormalities, particularly when the clinical signs and the results of neuroimaging methods are either non informative or non-conclusive ...

Influence of Pupillary Size on $$\overline {{\text{P100}}}$$ Latency Time of Pattern-Reversal VEP
1981The relation existing between exit pupil of the eye and latency time of pattern-reversal VEP’s major positive component was evaluated. VEP recordings were performed on 5 healthy subjects. The exit pupil of the eye was varied either pharmacologically or by placing stops in front of the eye.

Pattern reversal visual evoked potentials were recorded from 31 subjects who were occupationally exposed to lead and 54 non-exposed controls. No significant effects of lead were observed in the general subject population. However, when only non-smokers (17 lead-exposed and 27 controls) were evaluated, significant effects were found.
