✦ Synopsis


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 intensities of background illumination, they increased slightly and appeared to decrease with the strongest background illumination. The implicit time of oscillatory potentials 3 and 4 increased with stronger background illumination and decreased with the strongest background illumination. The results of the dominant frequency and the total power of the OPs correspond to the results in the time domain. The dominant power decreased from dark adaptation into light adaptation and did not show any systematic changes with increasing intensity of background illumination.

It has been shown that a single injection of iodoacetic acid selectively (but temporarily) abolishes the b-wave of the electroretinogram.

Previous reports have shown that an intravitreal injection of 2-amino-4-phosphonobutyric acid, a glutamate analogue that selectively blocks the photoreceptors' input to the on-bipolar cells, produces a rapid decrease in the amplitude of the electroretinographic b-wave. To our knowledge, the effect o

The oscillatory potentials are viewed by many as small oscillations of a highfrequency domain that ride on the b-wave of the electroretinogram. A study of electroretinograms and oscillatory potentials performed in 25 normal subjects was undertaken to substantiate my claim that oscillatory potentials

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
