Zusammenfassung

Mit kurzdauernden (0,1 sec) Rechteckreizen hoher Leuchtdichte (102fache ERG-Schwelle) wurden die oscillatorischen Potentiale im menschlichen ERG registriert. Es ergibt sich für Lichtreize verschiedener Wellenlänge für die Potentialkomponente OP2 beim Übergang von Hell- zu Dunkeladaptation eine deutliche Purkinjeverschiebung. Das registrierte Potential ist somit Ausdruck der jeweils aktiven Netzhautelemente.

Summary

In the human ERG the oscillatory potentials were evoked by right-angle stimuli of short duration (100 msec) and high luminance (102 times ERG-threshold). In the change from light- to darkadaptation there is a full Purkinje-shift for the potential component OP2 at stimuli of different wavelengths. The potential recorded, therefore, reflects the activity of retinal elements under operation.

Résumé

On enregistre les potentiels oscillatoires de l’ERG humain après stimulations rectangulaires courtes (0,1 sec) et de haute intensité (102 fois le seuil de l’ERG). Avec des stimulations lumineuses de différentes longueurs d’onde on observe un net d’effet Purkinje pour la composante de potentiel OP2 quand on passe de l’adaptation à l’obscurité à l’adaptation à la lumière. C’est pourquoi le potentiel enregistré est l’expression des élements actifs correspondants de la rétine.
