We recorded the pattern electroretinogram (PERG) to small (0.8 ~ and very large (15 ~ check sizes in normal subjects, in patients with early-stage glaucoma, and in patients with ocular hypertension. In glaucoma, the PERG amplitude was reduced. This reduction was more prominent for a check size of 0.

The human pattern-reversal retinal potential (PRRP) is a bioelectric~ response which reflects neural activity generated in the proximal retina. Visual diseases which affect the retinal ganglion cells and the optic nerve often produce significant reductions in the amplitude of the PRRP. PRRP amplitud
Diagnostic value of transient pattern electroretinogram (PERG), recorded by skin electrodes, was compared with Goldmann perimetry in cases of ocular hypertension and glaucoma. According to the assumption that the PERG mostly reflects activity of the retinal glanglion cells, and histological evidence
