Visual-Evoked Response Differentiation of Ischemic Optic Neuritis from the Optic Neuritis of Multiple Sclerosis

Electrophysiological assessment of optic nerve disease

“…Wilson 25 provided the first detailed analysis of the electrophysiological findings in nonarteritic ischaemic optic neuropathy (NAION), although 'delays' in the PVEP had previously been reported. 26 Both PVEP and flash VEPs (FVEPs) were examined in a mixed group of 15 arteritic and nonarteritic patients.…”

Brain Computer Interface Based on the Flash Onset and Offset Visual Evoked Potentials

“…FVEP can be measured in patients who have very poor visual acuity (Spehlmann, 1985), and some studies also reported that the FVEP can be measured in patients who can see flashes clearly but not pattern stimuli owing to their partial deficiencies in optical fiber connections between retina and visual cortex (Kriss et al, 1982;Wilson, 1978). These studies suggest that the FVEP is a widely measurable biosignal which has also been used as a control signal for BCI systems (Lee et al, 2005;Lee et al, 2006;Sutter, 1992).…”

“…FVEP has been a popular clinical index to monitor anesthesia level during surgery (Raitta et al, 1979;Uhl et al, 1980), to diagnose prechiasmal and retrochiasmal lesions (Carlin et al, 1983;Kriss et al, 1982;Markand et al, 1982;Wilson, 1978), to indicate intracranial pressure induced by head injury (McSherry et al, 1982), and to alarm brain death (Reilly et al, 1978;Trojaborg & Jorgensen 1973). FVEP can be measured in patients who have very poor visual acuity (Spehlmann, 1985), and some studies also reported that the FVEP can be measured in patients who can see flashes clearly but not pattern stimuli owing to their partial deficiencies in optical fiber connections between retina and visual cortex (Kriss et al, 1982;Wilson, 1978).…”

Comparative studies on pattern VECP between patients with ischemic optic neuropathy and optic neuritis

“…Previously, several reports of transient VECP studies in ION were described. Wilson (1978) reported a marked reduction in the amplitude and small increases in the P100 peak latency. Glaser & Laflamme (1979) reported that the combination of normal or mildly prolonged P100 latency was a possible indicator of ION.…”
