Conflicting results have been obtained concerning the parametric properties of the pattern electroretinogram. These discrepancies may be due to the large amount of variability inherent in recording amplitudes. We have found the variability within a single stimulus condition to be so large (ranging f

โฆ Synopsis
Pattern electroretinogram response and contrast sensitivity were evaluated in two groups of diabetic patients by means of psychophysical and electrophysiological methods. The first group consisted of subjects suffering from diabetic retinopathy in various stages of evolution; the second was composed of diabetic patients with no fundus alterations and with good visual acuity. In both groups of patients, when the pattern electroretinogram was altered, contrast sensitivity was also abnormal.

Thymoxamine constricts the pupil without significant effect on accommodation and was used in this study because of the extreme sensitivity of the pattern electroretinogram (PERG) to defocus at high spatial frequencies. Pilocarpine, used in previous studies, can cause an unpredictable spasm of accomm
The influence of adaptation on the oscillatory potentials of the human electroretinogram was studied in the domains of frequency and time. The amplitude of OP1 to OP4, the summed amplitude of OP1 to OP4, as well as the area, decreased from dark adaptation to light adaptation. With increasing intensi
Changes in the ERG and VEP across the life span were investigated. The dark adapted and scotopic ERGs both showed a progressive increase in the implicit times of the A and B waves and a reduction in the amplitude of the AB configuration. There was also an increase in the implicit times of the oscill
Electroretinographic responses to modulation of either luminance (focal ERG) or spatial contrast (pattern ERG) were recorded from the pigeon eye before and after intravitreal injection of glutamate analogues DL~ amino adipic acid (DL~ AA) and 2-amino-4 phosphonobutyric acid (APB). Both toxins revers
