Zusammenfassung

Unter einem gemischten Sektionsgut von 1561 Bulbi wurden in 10 meist diabetischen Augen autoptisch und histologisch ausgedehnte leistenförmige, oraparallele Anhebungen peripherer zystoider Netzhaut gefunden. In ihrem hinteren Abhang liegt eine Kette von inneren Schichtlöchern, welche in die periphere zystoide Degeneration hineinfü hrt. Die Veränderungen gleichen einem geöffneten Haifischmaul. Der Hinterrand der Basis vitrei inseriert am Kamm der Leiste. Dahinter besteht eine Glaskörperabhebung.

Die Leisten und Schichtlöcher werden als Folge chronischer, möglicherweise auch akuter Glaskö rpertraktion interpretiert, die offenbar zystoid degenerierte Netzhaut leichter anheben kann.

Abstract

10 predominantly diabetic eyes from a mixed collection of 1,561 enucleated specimens showed extended, linear, ridgelike elevations of the inner retinal layers within areas of cystoid degeneration. These ridges lie peripherally and run parallel to the ora. The posterior slope of each ridge contains a chain of inner retinal holes which extend into the cavities of the cystoid degeneration. The changes, viewed from behind, resemble an open sharkmouth. The posterior border of the vitreous base adheres to the crest of the ridge behind which the vitreous itself is detached.

The ridges and inner holes are thought to result from vitreous traction, chronic rather than acute, acting on peripheral areas of cystoid degeneration which can presumably be elevated more easily than normal retina.
