Pattern-onset visual evoked potentials in suspected multiple sclerosis.
Visual evoked potentials (VEPs) were obtained by monocular stimulation using a checkerboard pattern-reversal and pattern-onset technique. In 11 normal subjects, pattern-onset VEPs were generally larger, better defined, and less ambiguous than those elicited by pattern-reversal, because of the biphasic waveform characteristically obtained with pattern-onset stimulation. In 68 of 105 patients wit...
متن کاملThe Effect of Oral Verapamil on the Visual Evoked Potentials in Definite Multiple Sclerosis Patients
Introduction: Ionic channel rearrangements through the demyelinated axons or supporting media play significant role in remission of the neurological deficit in MS patients. In this study the effects of Verapamil as a calcium channel blocker on central conduction have been investigated through the evaluation of changes in P100 latency of the visual evoked potential. Method: This randomized doubl...
متن کاملVisual evoked potentials in the diagnosis of multiple sclerosis.
A three-year collaborative study was done on 96 patients presenting with signs of neurological dysfunction suggestive of multiple sclerosis. All were tested using Visual Evoked Potentials, with the final diagnosis not known to the tester. Patients with bilateral Visual Evoked Potential P1 wave conduction delays were more likely to have a subsequent diagnosis of MS, than those with unilateral de...
متن کاملContrast Sensitivity versus Visual Evoked Potentials in Multiple Sclerosis
PURPOSE To compare the Cambridge contrast sensitivity (CS) test and visual evoked potentials (VEP) in detecting visual impairment in a population of visually symptomatic and asymptomatic patients affected by clinically definite multiple sclerosis (MS). METHODS Fifty patients (100 eyes) presenting with MS and 25 healthy subjects (50 eyes) with normal corrected visual acuity were included in th...
متن کاملVisual and spinal evoked potentials in diagnosis of multiple sclerosis.
The measurement of cortical evoked potentials generated by pattern reversal is a sensitive technique for detecting demyelinating lesions in the anterior visual pathways.1 2 Similarly changes in the somatosensory evoked potential recorded over the cervical spine3 have been found in many patients with multiple sclerosis (MS).4 We have assessed the relative and complementary values of these two te...
