Visuell Evozierte Potentiale - Technik und klinische Anwendung

The recording of VEP requires the adherence to certain quality standards. On the one hand, biological (e.g. cooperation, visual acuity and alertness) and technical factors (e.g. position of electrodes and stimulation parameters) should be considered to eliminate confounding factors already present during the recording. On the other hand, a qualified interpretation requires the detection of artefacts and knowledge of the capabilities and limitations of VEP. In particular, the results must be placed in a clinical context to allow for a realistic interpretation. This article should provide the necessary background knowledge.
