"Pink eye" is the inaccurately used common name for this external ocular inflammation. Conjunctivitis encompasses both bacterial and viral infections as well as allergic inflammations. The eye is red from dilated blood vessels. This is an attempt of the eye to heal itself. Pink eye may be associated with a watery or mucus-like discharge, and some discomfort in the form of scratchiness, dryness, or overt pain. Vision is not usually affected.

True "pink eye" occurs in children, is a specific bacterial infection and is extremely contagious. The child with pink eye should be isolated from school and playmates. Those coming into contact must wash their hands immediately after contact. Pillowcases and towels should not be shared with others.

Treatment of conjunctivitis is specific for the condition. Antibiotics are used for bacterial infections, and anti-viral drops used in viral infections. Most viral infections are self limiting and the drops aid in the rapid clearing of the condition. Anti-allergic drops for allergic conditions control the itching, but the most accurate treatment is to remove the offending allergens.

Note: An eye can be described as being pink from conditions not related to infections. Internal inflammations, severe glaucoma, and trauma to the eye are examples. The vision is blurred or distorted. An ophthalmologist should be contacted if these conditions exist.
