Probably the most common and misunderstood eye disorder is pinkeye, also known as conjunctivitis. The concern of parents when they find out their child or someone in their childs school has pinkeye is understandable, but it is safe to say that most pinkeye is harmless, and with some common sense, can be easily controlled and eradicated.

What causes pinkeye?

Pinkeye occurs because the conjunctiva, the membrane that lines the eyelids and partially covers the eyeball, becomes inflamed. It is the most common disorder of the eye in North America.

Pinkeye can result from either allergic or infectious causes. Allergic conjunctivitis is often seasonal and can be caused by smoke, pollen, and other environmental irritants. There is often associated sneezing and runny nose, and can last for several months.

Infectious causes can be from bacteria or a virus. It can be quite contagious as it can spread by hands, fingers, towels, pillows, makeup, and washcloths. Children thought to have contracted pinkeye are often sent home from school or day care due to its contagiousness.

What are the symptoms?

Typical symptoms of conjunctivitis include redness of the eye, hence the name of pinkeye. Itchiness, excessive tearing, and pain may also occur. The eyelids often have a crusty, sticky discharge that makes opening them difficult at times. If the pinkeye is due to a virus, the discharge is usually watery, while bacterial conjunctivitis often has a yellow, green discharge. There may be a feeling of grittiness associated with the discharge. Rarely does pinkeye affect vision.

Often mistaken for pinkeye, is a chalazion, which is an inflamed sebaceous gland on the eyelid. These usually develop over several weeks and develop as a large hard lump on the eyelid. Usually harmless, chalazions, if severe, may have to be incised and drained.

How is it treated?

If you suspect that you or your child may have pinkeye, its a good idea to see the doctor. He or she may prescribe antibiotic eyedrops or ointments if an infectious cause is suspected. Sometimes a culture of the discharge is needed to determine the type of bacteria.

Middle ear infections usually go hand-in-hand with pinkeye, as often similar types of bacteria cause both. Your doctor should get a good look at your childs ears for a complete examination.
