[Developments in ophthalmologic electrophysiology].

During the last years electrophysiology in ophthalmology has been facilitated to a big extent by computerized methods. Thus it has become a suitable method for an increasing number of relevant diagnostic problems. To make comparisons between test results of different diagnostic places easier an international standard concerning the methodology of the electroretinogram (ERG) has been elaborated by the "International Society of Clinical Electrophysiology in Vision" (ISCEV). Aim of the present article is to give a short description of the ERG-standard and to review recent developments in clinical electrophysiology in ophthalmology (ca. since 1989).
