[6] TON exhibited its major influence on the amplitudes of the
VEPs presenting with absent
VEP waveforms in the majority followed by reduced amplitude ratios (>3 standard deviations) [Figure 1].

Similarly, intravitreal injection of the neurotoxin 6-hydroxydopamine into aphakic monkeys resulted in abnormalities in both the phase and amplitude of the pattern
VEP [6].
Considering the sensory-processing deficit on the way from the retina up to the primary visual area as indicated by the delayed P100 peak time of the pattern reversal
VEPs, we assume that the enhancement of the P3b component reflects compensatory brain activity enabling to achieve a normal behavioral reaction in our T1D subjects.
Results: The rats in the
VEPS group tended to have a higher survival rate than those in the PS group when undergoing HDF, although the difference was not significant.
Electrophysiologically
VEP, median nerve SEP (MSEP), tibial nerve SEP (TSEP), and BAEP values before treatment and after the first and second years of treatment were evaluated, and normal values from our neuro-physiology laboratory were used for determining the abnormal EPs values for the study In the examination of EPs, pathological values were accepted as elongations of P100 latency of more than 120 msec for
VEP or an intraocular latency difference of more than 10 msec, N20 latency longer than 21 msec for MSEP P40 latency longer than 42 msec for TSEP and I-III and III-IV wave interpeak latencies longer than 2 msec for BAEP.
This study was an attempt to compare visual evoked potentials (
VEPs) in primary open angle glaucoma (POAG) patients and controls so as to find any evidence of differences in
VEP latencies and amplitudes.
Visually evoked potentials (
VEPs) have been used to determine whether the photoreceptor sheet transplants to RD rats can activate the central visual system [204].
[5] Visual evoked potentials (
VEPs) provide noninvasive measures of transmission in the visual system.
The
VEPs were normal in 75% of patients with sudden visual loss and in 23% patients with chronic visual impairment.
Troy, NY, August 18, 2016 --(PR.com)-- Preliminary findings from a study of golf course businesses throughout the United States reveal that golf courses which participate in voluntary environmental programs (
VEPs) experience a variety of benefits.
Overall, 40 states will still have majority-white voting-eligible populations (
VEPs) in 2040, and 29 will in 2060.
