A, Norma l patient B, Patient w ith Fuchs endothelial dystrophy. Both were taken at the same magnification. Bottom micrograph shows larger, more irregular cells (polymegethism); the 3 dark areas toward the bottom are cornea guttae. (Courtesv of David Palay, MD. ) Figure 2-6 to the transfer of water from the corneal stroma and the maintenance of stromal deturgescence and transparency. Mitosis of the endothelium is rare in humans, and the overall number of endothelial cells decreases with age. Adjacent endothelial cells interdigitate in a complex way and form a variety of adherent junctions, but desmosomes are never seen between normal cells.
