From demyelination to neurodegeneration in multiple sclerosis: reassessing the role of visual evoked potential P100-N145 amplitudes: a missing piece of the puzzle? [PDF]

Frontiers in Neurology
BackgroundMultiple sclerosis (MS) is a chronic demyelinating disease with a heterogeneous clinical course, making long-term disability prediction challenging.

Longitudinal Analysis of P100 Wave Amplitude and Latency in Multiple Sclerosis: A 19-Year Retrospective VEP Study [PDF]

Diagnostics
Background: The diagnosis of multiple sclerosis (MS) relies on identifying neurological signs and symptoms, supported by evidence of central nervous system (CNS) dissemination of lesions across time and space.

Normative values of visual evoked potential in adults

Indian Journal of Ophthalmology, 2021
Purpose: Visual evoked potentials (VEP) are used to determine the function of visual pathway from the optic nerve to visual cortex. Various factors may affect VEP response, viz., technical and environmental.

Long term decline of P100 amplitude in migraine with aura [PDF]

Journal of Neurology, Neurosurgery & Psychiatry, 2000
To investigate visual function in migraine using visual evoked potentials.Electroretinograms (ERGs) and visual evoked potentials (VEPs) to single flash (SF) and pattern reversal (PR) stimuli were studied in 92 migraine subjects and 62 controls.In subjects with migraine, ERGs to single flash were normal.
