Both transmission (TEM) and scanning electron microscopy (SEM) demonstrate that typical fibrils are the dominant feature of the pseudo‐exfoliation (PE) material. The purpose of this work has been to examine whether the TEM and the SEM fibrils are identical, and to determine to which extent the morphology of the PE material is changed during the preparation for SEM, especially by the drying procedure. Specimens from lenses with PE, which had beforehand been prepared for and examined by SEM, were embedded, sectioned and examined by TEM. The results indicate that, as far as it can be seen by this method, the changes induced in the PE material by the drying procedure are not substantial. The TEM and the SEM fibrils are identical.
