Conjunctiva

From Freepedia

The conjunctiva is a membrane that covers the sclera (white part of the eye) and lines the inside of the eyelids. It helps lubricate the eye by producing mucus and tears, although not as much tears as the lacrimal gland. (London Place Eye Center, 2003).

Histology

The conjunctiva is typically divided into three parts:

1. Palpebral or tarsal conjunctiva - the conjunctiva lining the eyelids
2. Fornix conjunctiva - the conjunctiva where the inner part of the eyelids and the eyeball meet
3. Bulbar or ocular conjuctiva - the conjunctiva over the eyeball

Diseases and disorders

Main article: List of eye diseases and disorders

Disorders of the conjunctiva and cornea are a common source of eye complaints. The surface of the eye is exposed to various external influences and is especially suspectible to trauma, infections, and allergic reactions. Degeneration and dystrophia are less common causes of problems. The conjunctiva is best known because of its inflamed state, conjunctivitis, which is more commonly known as 'pink eyes'.
