Topographical differences in cell area at the surface of the corneal epithelium of the pigmented rabbit.

Corneas from female pigmented rabbits were prepared for scanning electron microscopy at 15.00 h. The superior-temporal and inferior-nasal quadrants were evaluated at 500X at-stage magnification, normal to the corneal surface, at central, paracentral and peripheral sites. Non-parametric statistical analyses of the histograms of cell surface areas at each site from seven corneas revealed significant differences between the three sites but not between superior and inferior quadrants.
