Visual Evoked Potentials in Neonatal Hyperbilirubinemia

open access: yesJournal of Child Neurology, 2006
The management of neonatal hyperbilirubinemia is very standardized. However, there is a lack of an objective method to evaluate the cerebral effects of bilirubin apart from brainstem auditory evoked potentials. There were few studies evaluating the effects of hyperbilirubinemia or phototherapy on the visual pathway in infants with hyperbilirubinemia ...

Visual Evoked Potentials

Journal of Clinical Neurophysiology, 1994
The recording of visual evoked potentials (VEPs) is an important means of obtaining reproducible, quantitative data on the function of the anterior visual pathways. In this review, the technical aspects of recording VEPs are briefly discussed, components of the VEPs are described, and the clinical uses of VEPs are considered.

Visual Evoked Potentials

American Journal of Electroneurodiagnostic Technology, 2008
Pattern reversal evoked potentials (PVEPs) are a noninvasive procedure that are useful for detecting lesions of the visual pathways. This article reviews anatomy of the visual pathway and the testing protocols for fullfield and hemifield PVEP and flash (goggle) visual evoked potentials (FVEP).

Visually evoked potentials

2019
The term visually evoked potential (VEP) refers to electrical potentials recorded from scalp overlying visual cortex that have been extracted from the electroencephalogram by signal averaging. Usually the recording electrode is placed on the midline of the occipital scalp at the back of the head.

The Multifocal Visual Evoked Potential

Journal of Neuro-Ophthalmology, 2003
With the multifocal technique, visual evoked potentials (VEPs) can be recorded simultaneously from many regions of the visual field. For the multifocal VEP (mfVEP), the patient views a display that typically contains 60 sectors, each with a checkerboard pattern.

Visual evoked potentials of infants

Revue d&'apos;Electroencéphalographie et de Neurophysiologie Clinique, 1972
Resume Les auteurs ont montre dans un travail anterieur que la configuration du P.E.V. chez le nouveaune et chez l'enfant de 3 mois montre une grande var iabilite diurne ; par ailleurs et contrairement au P.E.V. de l'adulte la configuration de ce P.E.V. n'est pas liee au cycle de veille-sommeil.

Visual evoked potentials in sarcoidosis

Neurology, 1981
The visual evoked potential to pattern reversal was recorded in 50 patients with sarcoidosis. Abnormalities of latency and amplitude were found in 15 patients (30%), including all 4 patients with clinically evident brain disease and 4 of 17 patients with overt ocular disease. Twenty-nine patients had no clinical evidence of ocular or neurologic disease,

Biofeedback of Visual Evoked Potentials

International Journal of Neuroscience, 1986
The present study investigated the operant conditioning of visual evoked potentials within a latency range between 200 and 600 ms using a visual discrimination task, and scrutinized whether biofeedback-induced potential shifts covaried with behavioral responses (reaction time, RT).
