Because the corneal endothelium is the primary site for the metabolic pump that maintains corneal deturgescence, any change in the morphologic characteristics of endothelial cells is of considerable interest. It has been suggested that the functional reserve of the endothelium may be compromised with more severe cases of polymegethism.

Adverse effects of contact lens wear on physiologic features of the cornea were recently emphasized by the discovery that polymegethism and pleomorphism occurred with contact lens wear.¹ These changes could be ascribed to oxygen shortage, carbon dioxide buildup, and pH changes under the lens.¹ The same phenomena could be induced in the corneal endothelium of patients suffering from long-standing ptosis, which results in a decreased oxygen tension of approximately one third of the oxygen available under open-eye conditions.²
