Also called "pinkeye," conjunctivitis is an inflammation of the conjunctiva,
which is the clear membrane that covers the eyeball. Symptoms in the affected
eye include a bloodshot appearance, crusty discharge, and discomfort that may
feel like something has gotten in the eye. Conjunctivitis is frequently caused
by a viral infection, sometimes of the same viruses that cause colds. In such
cases, conjunctivitis could be called "a cold in the eye" and is really no more
serious than any other cold. Other causes of conjunctivitis include bacterial
infections, allergies, environmental irritants such as smoke or pollution,
exposure to chemicals such as chlorine or contact lens solution, or injuries to
the eye.
Medical treatment varies depending on the cause of the inflammation. Common viral conjunctivitis does not require treatment—but if conjunctivitis is due to the herpes virus, urgent treatment is necessary. For bacterial eye infections, antibiotic ointment or oral antibiotics are usually prescribed; for allergic conjunctivitis, prescription eye drops and/or antihistamines may be used.
