The effect of anoxia on the human corneal epithelium. 1981

D J O'Leary, and G Wilson, and D B Henson

After 6 hr of oxygen deprivation, the human corneal epithelium had not swollen. Over the first hour of recovery from anoxia, the epithelium shrank by up to 20% before returning toward its predeprivation thickness. No fluorescein staining of the epithelium was seen during these experiments, but some subjects were able to discern halos immediately after deprivation. We conclude that homeostasis is maintained in the corneal epithelium for up to 6 hr of anoxia, but the intercellular spaces may be altered.

D003315	Cornea	The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses.
