Summary

Enucleated bull's eyes were perfused with blood and ERG recorded, with special attention paid to the slow components. When the blood flow was interrupted, the ERG components vanished in the following order: b wave, c wave, off-effect (d wave), and a wave. When the perfusion was continued afterward, we saw a variation in the standing potential that hinted at the biochemical activities causing slow electrical potentials of the retina.

Zusammenfassung

Von enukleierten, mit Blut perfundierten Rinderaugen wurde das ERG unter besonderer Berücksichtigung der langsamen Komponenten abgeleitet. Nachdem die Perfusion unterbrochen worden war, verschwand zunächst die b-Welle, dann die c-Welle, der off-Effekt (d-Welle) und schließlich die a-Welle. Wir konnten eine Änderung des Bestandspotentials beobachten, nachdem die Perfusion wieder einsetzte, die Hinweise auf Stoffwechselfunktionen gab, die den elektrischen Phänomenen zugrunde liegen können.
