Abstract

The operation of a computer which averages low-amplitude electroretinograms is described. The computer has been used to detect electroretinograms which were recorded in an investigation of area-luminance and stray-light effects within the eye. Large test stimuli were found to be more effective than small for producing responses of fixed size. Although the observers reported that the stimulus spread over much of the retina larger photopic responses appeared when the stimulus was centered on the fovea than on neighboring areas. The waveform of the response was found to depend on both the color and the position of the stimulus on the retina.
