Although the cornea may look clear and seem to lack substance, it is a highly organized tissue. Unlike most tissues in the body, the cornea contains no blood vessels to nourish or protect it against infection. Instead, the cornea receives its nourishment from tears and the aqueous humor (a fluid in the front part of the eye that lies behind the cornea).
Cornea and Corneal Disease
The cornea is the eye’s outermost layer. It is the clear, dome-shaped surface that covers the front of the eye.
