Summary

A case of transitory cortical blindness was presented in connection with an electrical accident. As the tempero-occipital region had been previously damaged due to concussion, it was not possible to differentiate whether the electrical injury was the causal or only the precipitating factor. However, a differentiation with regard to simulation and hysteria could be made with the help of the VER. Therefore, the VER represents a valuable aid in the differential diagnostic clarification of cortical blindness.

Zusammenfassung

Beim vorliegenden Fall ist im Rahmen eines Stromunfalles eine passagere Rindenblindheit aufgetreten. Da im tempero-occipitalen Bereich bereits eine Vorschädigung auf Grund einer commotio cerebri bestand, ist eine Differenzierung, ob der Stromunfall der ursächliche oder auslösende Faktor war, nicht möglich. Eine Abgrenzung hinsichtlich Simulation und Hysterie konnte durch visuell evozierte potentiate (VER) getroffen werden. Somit stellt das VER differentialdiagnostisch eine wertvolle Hilfe zur Abklärung der Rindenblindheit dar.
