Abstract

An electron microscopical study of vitreous structure in 14 eyes suffering from different types and durations of vitreous hemorrhages submitted to vitrectomy showed the typical stages of disintegration of erythrocytes. Neither the type (retrovitreal, intravitreal or combined retro- and intravitreal) nor the duration of the vitreous hemorrhages influenced the histological picture significantly. In cases of shrinkage of the vitreous body the collagen fibrillar meshwork showed normal periodicity of 640 Å, partly split and irregular.

Zusammenfassung

Eine elektronenmikroskopische Studie an Vitrektomiematerial von 14 Augen mit verschiedenen Arten (intravitreal, subvitreal oder kombiniert intra- und subvitreal) und unterschiedlicher Dauer von Glaskörperblutungen zeigt die typischen Stadien der Autolyse der Erythrozyten. Weder die Art noch die Dauer der Glaskörperblutung beeinflußt signifikant das histologische Bild. In Fällen von Glaskörperschrumpfung zeigen die Kollagenfibrillen eine annähernd normale Periodizität von 640 Å, das Maschenwerk ist teilweise durchbrochen und unregelmäßig.
