Definition / Description
Conjuctivitis is an inflammation (redness) of the lining of the white part of the eye and the underside of the eyelid (conjunctiva). It can be caused by infection, allergic reaction, or physical agents like infrared or ultraviolet light.
Conjunctivitis is the inflammation of the conjunctivae, the thin, delicate membranes that cover the eyeball and line the eyelid. Conjunctivitis is a common eye problem because the conjunctivae are continually exposed to microorganisms and environmental agents that can cause infections or allergic reactions. Conjunctivitis can be acute or chronic depending upon how long the condition lasts, the severity of symptoms, and the type of organism or agent involved. It can affect one or both eyes. If it is caused by infection, it can be easily transmitted to others during close physical contact, particularly among children in a daycare center. Other names for conjunctivitis include pinkeye and redeye.
