Summary

Intravitreal implantation of dermal connective tissue in rabbits caused a fibroplasia resulting in vitreous retraction, retinal detachment, and traction of nervous tissue from the optic nerve into the vitreous space.

Following implantation into eyes with an intact vitreous the incidence of retinal detachment was low (2 eyes of 12). When the hyaluronic acid of the vitrous was degraded by hyaluronidase prior to implantation, 9 eyes of 12 developed a progressive detachment of the retina, usually within one or two months. Intravitreal fibroplasia was found to be an important pathogenic factor causing detachment of the retina.

Zusammenfassung

Autologes Bindegewebe aus der Haut von Kaninchen wurde in den Glaskörper der Tiere implantiert. Das kleine Bindegewebsstückchen verursachte eine Fibroplasie mit Glaskörperschrumpfung, Netzhautablösung und Traktion des Nervus opticus in den Glaskörperraum herein.

Nach Implantation in Augen mit intaktem Glaskörper entwickelte sich nur selten, in 2 von 12 Augen, eine Netzhautablösung. Nachdem die Hyaluronsäure des Glaskörpers mit Hyaluronidase ausgeschaltet worden war, konnte in 9 von 12 Augen eine progressive Ablösung der Netzhaut beobachtet werden.

Offenbar war die intravitreale Fibroplasie ein wichtiger pathogenetischer Faktor für die Entwicklung einer Netzhautablösung.
