A comparative study of visual evoked potentials in optic neuritis and optic neuritis with multiple sclerosis.
OBJECTIVE To compare the visual evoked potentials (VEP) in patients with acute optic neuritis, recurrent optic neuritis, and optic neuritis with multiple sclerosis. MATERIAL AND METHOD The authors retrospectively reviewed VEP latency records of the patients with optic neuritis in Siriraj Hospital from 1995 to 2005 and divided them into three groups, acute optic neuritis, recurrent optic neuri...
متن کاملVisual function and pattern visual evoked response in optic neuritis.
The disparity between clinical visual function and pattern visual evoked response (VER) was studied in 53 patients who had suffered an attack of optic neuritis (ON) more than six months before. The visual functions tested included Snellen visual acuity, colour vision, visual field, and contrast sensitivity. The effect of pattern presentation, check size, and luminance was tested by recording VE...
متن کاملSpatial tuning function of pattern visual evoked potentials in multiple sclerosis patients without optic neuritis history.
AIM To explore amplitude and latency-check size function in multiple sclerosis (MS) patients without optic neuritis history. METHODS Thirty-six MS patients and 21 control subjects were included. Pattern visual evoked responses to ive check sizes (2°, 1°, 30', 15', and 7') were recorded. RESULTS P100 amplitudes were significantly reduced in 2°, 1° and 7' checks and, P100 latencies were signi...
متن کاملVisual-evoked response differentiation of ischemic optic neuritis from the optic neuritis of multiple sclerosis.
Fifteen patients with ischemic optic neuritis studied electrophysiologically had a characteristic change of marked reduction in the amplitude of the visual-evoked response even when loss of vision was moderate. The optic neuritis of multiple sclerosis rarely produced this change. Occasionally, small increases in the latent period of the visual-evoked response were recorded from the patients wit...
متن کاملInterrelationship of optical coherence tomography and multifocal visual-evoked potentials after optic neuritis.
PURPOSE Acute optic neuritis (ON) is often followed by recovery of visual function. Although this recovery is mainly attributable to resolution of the acute inflammation, the redistribution of ion channels along the demyelinated membrane, and subsequent remyelination, part of it may be the result of neural plasticity. In the present study, the interrelationship was examined between structural (...
