Cell size-shape relationships in corneal endothelium.

The shape of corneal endothelial cells was studied from specular photomicrographs of 121 normal corneas. The predominant number of cells were hexagonal in shape (48% to 90%), with pentagonal (15% to 35%) and heptagonal (25% to 38%) cells constituting the greater portion of the remaining endothelium. Corneal endothelium with a greater number of hexagonal cells demonstrated minimal variation in cell size.
