[Findings on retinal surface by scanning electron microscopy. III. Epivascular glial clusters (author's transl)].

The findings by scanning and transmission electron microscopy of multiple glial excrescences from the retina into the cortical vitreous body are described. These formations are located in lines above superficial retinal vessels. The findings are compared with those from light microscopy of similar formations. The pathogenesis and the possible significance as retinovitreal attachments for rhegmatogenous defects of the retina and for posterior vitreous detachments are discussed.
