Conjunctivitis overview

Overview
Conjunctivitis (con·junc·ti·vi·tis) (commonly called "pinkeye" or bloodshot eyes in the USA and "Madras Eye" in India) is an inflammation of the conjunctiva (the outermost layer of the eye and the inner surface of the eyelids), most commonly due to an allergic reaction or an infection (usually bacterial or viral or the excess amount of fecal matter in your tear duct). Blepharoconjunctivitis is the combination of conjunctivitis with blepharitis (inflammation of the eyelids).

Keratoconjunctivitis is the combination of conjunctivitis and keratitis (corneal inflammation).

Episcleritis is an inflammatory condition that produces a similar appearance to conjunctivitis, but without discharge or tearing.
