    Notes: Summary The trabecular meshwork of a non-glaucomatous eye with the exfoliation syndrome was investigated. The exfoliation material was found mainly in massive deposits in the subendothelial region of the outer and inner wall of Schlemm's canal, in the cribriform area and the uveal meshwork. The other alterations of the trabeculum corneosclerale corresponded to the age of the patient. The concept that the accumulation of exfoliation material is an important pathogenetic factor in the development of glaucoma was not confirmed by this study.

    Description / Table of Contents: Zusammenfassung Elektronenmikroskopische Untersuchungen haben ergeben, daß in Fällen von fleckförmiger Hornhautdystrophie (Groenouw II) Ablagerungen von sauren Mucopolysacchariden in den verschiedenen Schichten der Hornhaut in vielgestaltiger Form vorkommen können. Auf Grund der jetzt durchgeführten Untersuchungen kann festgestellt werden, daß die massiven Trübungen der parazentralen und peripheren Bereiche in den tiefen Schichten teils durch verstreute vesikuläre Anordnung, vor allem aber durch plaqueartige Ablagerungen von Speicherstoffen im Grenzbereich von Stroma und Descemetscher Membran entstehen.
    Notes: Summary Electron microscopic studies proved, that in cases of macular corneal dystrophy (Groenouw II) abnormal deposits of acid mucopolysaccharide are demonstrable in the different layers of the cornea in a polymorphic form. Because of the investigations now performed it can be established, that the opacities of the paracentral, deep corneal layers result from both dispersed vesicular and plaque-like deposits of storage material in the border area of the stroma and Descemet's membrane.

    Description / Table of Contents: Zusammenfassung Die lichtmikroskopischen und die ultrastrukturellen Untersuchungen einer Hornhaut mit einer tiefen Keratomykose (Aspergillose) ließen erkennen, daß die Keratozyten im Verbreitungsgebiet der Pilze teilweise schwer geschädigt, teilweise jedoch in ihrer Zellstruktur gut erhalten sind. Als zellige Reaktion findet man vor allem Makrophagen, welche die Hyphen mit Pseudopodien umgreifen oder am apikalen Ende kappenartig umschlingen. Wie in zahlreichen Schnitten beobachtet werden konnte, wird die Zellwand der Pilze von den Phagozyten nur schwer aufgelöst, das Zytoplasma hingegen offenbar früher und schwerer geschädigt. Die zellige Reaktion in der Vorderkammer ist massiv und intensiv, wobei wiederum vor allem Makrophagen teilnehmen.
    Notes: Summary Light-microscopic and ultrastructural examinations of a corneal button with deep keratomycosis revealed that keratocytes are partly injured and partly of normal structure. In the cellular reaction, macrophages especially, are found that encircle hyphae with pseudopodia or cover the apical end of the fungi. In many sections, the fungal walls are very resistant to phygocytosis, but, on the contrary, the cytoplasm is damaged earlier and more severely. The cellular reaction in the anterior chamber is massive and intensive with predominance of macrophages.
