Abstract
Routine examinations with an electroretinogram (ERG) were performed on a large number of patients. The results are discussed in those areas where the ERG aided in diagnosis, contributed to the understanding of a disease, or assisted in following the course of a disease. The electro-oculogram (EOG) as an adjunct to the ERG is also discussed. Mention is made of the few diseases which may be detected only by the EOG. The use of both the ERG and EOG may provide more insight into the nature and extent of a disease process and at times may aid in providing a specific diagnosis.
