[Findings on retinal surface by scanning electron microscopy. II. Vitreous detachment (author's transl)]

Abstract

The authors describe their findings by scanning electron microscopy of the surface of the retina following secondary and primary senile posterior vitreous detachment. These findings are correlated with those of transmission electron microscopy. Extended nets formed by vitreous fibrils can be found on the retinal surface. The fibrils form a continuous feltwork, which cannot be traced by biomicroscopy or dissection of enucleated globes. This feltwork desintegrates in places or over a wide area and the basal membrane of the Müller cells becomes exposed. Structural differences in consequence of the two examination techniques well as possible artifacts are shown.
