Specular microscopic observations of the clinically normal canine corneal endothelium

Specular microscopy and pachometry were performed on seven clinically normal anesthetized young adult dogs. Endothelial cells of the central cornea formed a mosaic-like pattern of hexagonal cells 15 to 20 micrometers in diameter; the average number of cells per millimeters squared was 2,816 +/- 187 SD. Average corneal thickness of 0.62 +/- 0.047 SD mm.
