The conjunctiva is an opaque membrane that covers the front of the eye and folds to cover the back of the eyelids.

Patients with conjunctivitis have swelling of the eyelids, eye redness, and either tearing or mucous-like discharge, often with crusting in the morning.

Inflammation of the conjunctiva is called conjunctivitis.


Conjunctivitis is usually the result of an infection, although rare autoimmune diseases can cause this as well.

Conjunctivitis mostly resolves without treatment. Antiinflammatory therapy may speed recovery, while antibiotic eyedrops are almost never helpful. Very rarely, systemic therapy (pills) are used to treat conjunctivitis.
