METHODS ERGs were recorded in 20 patients (age 33–65 years) with advanced … WebThe electroretinogram or electroretinography (ERG) records the electrical response evoked from the entire retina by a brief flash of light and consists of an “A” wave, a photoreceptor response, and a “B” wave that emanates from the Muller and bipolar cells. The ERG provides information about the performance of the rods and cones.
WebThe reduced ERG A-wave amplitude in D2 mice likely results from dysfunctional photoreceptor responses. These data suggest that the smaller pupil sizes prevented light from reaching the photoreceptors and thus contributed to reduced ERG sensitivity in D2 mice.
