Relative state of dehydration of cornea is maintained by: (A) Active Na-K-ATPase pump of the corneal endothelium, (B) Peculiar arrangement of corneal lamellae, (C) Avascularity of cornea, (D) All of the above.
Answer is A. Corneal transparency The transparency is the result of : 1) Peculiar arrangement of corneal lamellae (lattice theory of Maurice), 2) Avascularity, and 3)Relative state of dehydration, which is maintained by barrier effects of epithelium and endothelium and the active bicarbonate pump of the endothelium.
