Conjunctiva

Definition

The conjunctiva is a thin, clear membrane that covers the inner surface of the eyelid and the white part of the eyeball (the sclera). It contains many tiny blood vessels.

Inflammation of the conjunctiva is called conjunctivitis. It makes the surface over the white part of the eye look red.
