Conjunctivitis

Definition

Conjunctivitis is swelling (inflammation) or infection of the membrane lining the eyelids (conjunctiva).

Alternative Names

Inflammation - conjunctiva; Pink eye

Causes

The conjunctiva is exposed to bacteria and other irritants. Tears help protect the conjunctiva by washing away bacteria. Tears also contain proteins and antibodies that kill bacteria.

There are many causes of conjunctivitis. Viruses are the most common cause. Viral conjuctivitis is referred to as "pink eye." Pink eye can spread easily among children.

Other causes include:

Newborns can be infected by bacteria in the birth canal. This condition is called ophthalmia neonatorum, and it must be treated immediately to preserve eyesight.

Symptoms

Exams and Tests

Treatment

Treatment of conjunctivitis depends on the cause.

Allergic conjunctivitis may respond to allergy treatment. It may disappear on its own when you avoid your allergy triggers. Cool compresses may help soothe allergic conjunctivitis.

Antibiotic medication, usually eye drops, is effective for bacterial conjunctivitis. Viral conjunctivitis will disappear on its own. Many doctors give a mild antibiotic eyedrops for pink eye to prevent bacterial conjunctivitis.

You can soothe the discomfort of viral or bacterial conjunctivitis by applying warm compresses (clean cloths soaked in warm water) to your closed eyes.

Outlook (Prognosis)

The outcome is usually good with treatment.

Possible Complications

Reinfection within a household or school may occur if you don't follow preventive measures.

When to Contact a Medical Professional

Call for an appointment with your health care provider if your symptoms last longer than 3 or 4 days.

Prevention

Good hygiene can help prevent the spread of conjunctivitis:
