719. Membrane pupillaris

The iris is removed. From all over the area to push the vessel back to the center of the lens lateral pole which is itself free of the vessels is a sign of incipient recovery, which eliminates the normal state gradually the whole membrane. The arteries of the papillary membrane arise from the major circle of iris, the edge loops, the venous flow in the veins vorticosae.

(Nach O. Schultze.)

Die Iris ist entfernt. Von der ganzen Umgebung schieben sich die Gefäße gegen das Zentrum des lateralen Linsenpoles hin, der selbst von Gefäßen frei ist Das ist jedoch schon ein Zeichen beginnender Rückbildung, welche im normalen Zustand nach und nach die ganze Membran beseitigt. Die Arterien der Papillar- membran entspringen aus dem Circulus iridis major, die Randschlingen, die Venen fließen in die Venae vorticosae.
