The present study attained the detailed clinical and electrophysiological profile of those patients who were investigated for VEPs for different visual disorders.
Magnetic resonance imaging (MRI) cervical spine with contrast and visual evoked potentials (VEP's) were done when clinically indicated.
Given these eight FFCs, the program calculated the mean FFC and the radius of a 95% confidence circle using the T2[sub]circ statistic.[8] The signal-to-noise ratio (SNR) was defined as the ratio of the mean amplitude of the FFC to the radius of the 95% confidence circle, and it was used to assess the reliability of the VEP. Thus, SNR >1 indicated a significant response at the 0.05 level, suggesting normal electrophysiologic activity of the optic nerve, recorded as SNR negative; SNR ≤1 indicated the response was similar to or weaker than the background noise at the 0.05 level, suggesting abnormal electrophysiologic activity of the optic nerve, recorded as SNR positive.

Details in MRI reports issued by Consultant Radiologists and data in the most recent CSF and VEP reports were extracted and stored in the structured data collection sheet.
Six features for VEPs (O2 electrode: the latencies of P3 component and C2 component, the amplitude of C1 component; O1 electrode: the latency and amplitude of P3 component; Oz electrode: the amplitude of P3 component, termed as [x.sub.1] to [x.sub.6], respectively) were chosen for establishing the classification model to distinguish visual discomfort-related excessive crossed disparity.
Visual dysfunction that occurs in PD is subtle and could be easily demonstrated through electrophysiologic testing, such as the visual evoked potential (VEP).
The two flickering stimuli had frequencies of 1 Hz and 15 Hz to induce visual-evoked potential (VEP) and steady-state visual-evoked potential (SSVEP), respectively.
Forty reversals of a high-contrast black and white checkerboard pattern within 20 seconds evoked pattern-reversal VEPs. Two checkerboard stimulations with check sizes of 40 arcmin (PR-VEP 40') and 20 arcmin (PR-VEP 20') were used.
Six hours after LPS administration, hemodiafiltration (HDF) was performed for 30 minutes using a PS or VEPS membrane under general anesthesia.
Visual evoked potentials (VEPs), brainstem auditory evoked potentials (BAEPs), and somatosensory evoked potentials (SEPs) are used to electrophysiologically define lesions in CNS afferent pathways, and they reveal the multifocal characteristics of the disease.
The objective of this paper is to study visual evoked potentials (VEPs) in primary open angle glaucoma.
