Visual evoked cortical potential to paracentral retinal stimulation in chronic glaucoma, ocular hypertension, and an age-matched group of normals

Abstract: Visual evoked cortical potentials (VECPs) to midperipheral stimulation of the visual field were elicited in age-matched groups of patients with unilateral chronic simple glaucoma or ocular hypertension and normal subjects. With a multimodal stimulus approach comprising transient and steady-state pattern reversal and transient onset-offset VECPs, 82.1% of the glaucoma group and 50.9% of the ocular hypertensives revealed significant abnormalities (p less than 0.01) in one or more of the electrophysiological feat… Show more

“…Thus, glaucomatous field defects may be more detectable with the use of steady-state stimuli. This view is supported by the results of a well-controlled full-field study [12], while another study found that steady-state stimuli made a useful contribution as part of a multimodal stimulus approach [13].…”

“…Abnormalities in latency and/or amplitude have also been demonstrated in glaucomatous and ocular hypertensive (OHT) eyes when the pattern visual evoked potential (PVEP) was recorded alone (Abe and Iwata, 1976;Motolko et al, 1982;Atkin et al, 1983;Towle et al, 1983;Follmann et al, 1984;Howe and Mitchell, 1986a; or simultaneously recorded with the PERG (Bobak et al, 1983;Porciatti and von Berger, 1984;Howe and Mitchell, 1984;Papst et al, 1984b;van Lith et al, 1984;Ringens et al, 1986). Bobak et al (1983) demonstrated that similar abnormalities in the signal-to-noise ratio occurred in both the PERG and PVEP in 3 out of 4 glaucoma eyes and in 10HT eye.…”

“…Thus, large defects in the upper field can be missed with the conventional VEP. In general, the lack of spatial information limits the usefulness of the technique [6,11-15]. …”
