Summary

The findings by scanning electron microscopy on three retinal holes are described. An outgrow of a glial membrane with microvilli from the holes to the retinal surface can be seen. This epiretinal cell membrane grows on a felt of collagen fibres of the vitreoretinal borderlayer. Rudiments of visual receptors project from the deep walls into the holes. The layer of the pigment epithelial cells beneath the holes is remarkable by the abundance of microvilli.

Zusammenfassung

Es werden die rasterelektronenmikroskopischen Befunde an drei Netzhautrundlöchern beschrieben. Man findet eine aus den Foramina auf die Netzhautinnenfläche auswachsende Gliamembran mit mikrovillöser Oberfläche. Diese Zellmembran schiebt sich auf einen Kollagenfaserfilz der umgebenden vitreoretinalen Grenzschicht. Rudimente von Sinneszellrezeptoren stehen an den tiefen Lochrändern. Die Schicht der Pigmentepithelien unter den Foramina ist durch exzessiven Microvillibesatz ausgezeichnet.
