A NOTE ON THE PSEUDO-EXFOLIATION FIBRILS

Abstract

Transmission (TEM) and scanning electron microscopy (SEM) demonstrated that fibrils were the dominant feature of the pseudo-exfoliation (PE) material [in man]. Whether the TEM and SEM fibrils are identical was examined, and to what extent the morphology of the PE material was changed during the preparation for SEM, especially by the drying procedure, was determined. Specimens from lenses with PE, which beforehand had been prepared for and examined by SEM, were embedded, sectioned and examined by TEM. Apparently the changes induced in the PE material by the drying procedure were not substantial. The TEM and SEM fibrils are identical.
