Summary

The ERG was used to assess the alteration of retinal function induced by experimental retinal detachment and surgical reattachment in owl monkeys.

All electrical activity can be abolished within seven days after the production of total retinal detachment. Reattachment of the retina resulted in an early and progressive recovery of the ERG. The amplitude of the b-wave and the threshold intensity of light necessary to evoke an ERG were linearly related to the time after the retina was reattached.

Zusammenfassung

Das ERG wurde benutzt um Änderungen in der retinalen Funktion festzustellen, die hervorgerufen wurden durch experimentelle Netzhautablösung und operative Wiederanheftung der Netzhaut am Eulenaffen.

Die elektrische Aktivität der Netzhaut war mit Entwicklung einer totalen Netzhautablösung innerhalb von 7 Tagen völlig ausgelöscht. Kurz nach Wiederanheftung der Netzhaut erholte sich kontinuierlich das ERG. Die Höhe der b-Welle und der Schwellenwert der Lichtintensität, die nötig waren, ein ERG hervorzurufen, waren linear abhängig von der Zeit der Wiederanheftung der Netzhaut.
