Preferred Label : cornea;
Definition : 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. (Cline et al., Dictionary
of Visual Science, 4th ed) [MeSH];
