The ultrastructure of Descemet's membrane. III. Fuchs' dystrophy
W. M. Bourne, D. H. Johnson and R. J. Campbell
The ultrastructure of Descemet's membrane was studied by transmission
electron microscopy in corneal buttons removed from 11 phakic eyes with
Fuchs' dystrophy. Abnormalities in Descemet's membrane consistent with
abnormal endothelial function early in life (prior to age 20 years) were
present in all corneas. Thus, despite the relatively late clinical onset of
Fuch's dystrophy, endothelial abnormalities are present quite early in life
in this disease. An abnormal fibrillar layer was thicker in those corneas
with greater stromal and epithelial edema, possibly indicating that this
layer is formed mainly during periods of endothelial decompensation.
