Pattern and Ganzfeld electroretinograms in macular disease.
The pattern electroretinogram has been found to be abnormal in all except three cases of maculopathy. This is in contrast to other electrophysiological tests, which are frequently unaffected. The degree of reduction is related to the loss of visual acuity. The response to focal flashes is less affected than the response to pattern.
