Conjunctivitis
Dear Dr. Welty,
My child was sent home from school because of "pink eye". I took her to our doctor who diagnosed conjunctivitis, and started her on some eye drops. What exactly is conjunctivitis? Is it contagious? Does it cause problems with eyesight?
Conjunctivitis is a condition that causes inflammation of the eye lining, or conjunctiva. This inflammation is also called "pink eye" or "red eye". It is usually due to an infection, but can also be caused by allergic reactions, physical or chemical irritation, or a foreign body. On rare occasions, it may be associated with a more serious systemic condition.
Conjunctivitis is a common source of school referrals and physician office visits. It is diagnosed when the white portion of your child's eye and the inside of the lids become red. It may be associated with tearing, burning, and a discharge. The discharge may be watery or thick, and the eyelids may be stuck together in the morning. There may be associated cold symptoms, fever, or sore throat. Vision is not usually affected.
Since the infectious type is caused by either a bacteria or a virus, it is usually quite contagious. Your child should see a doctor as soon as possible so appropriate treatment can be instituted.
Conjunctivitis commonly lasts five to seven days, but in the rare case can last up to two weeks. One should avoid direct contact with the eyes and eye drainage. Good hand washing and avoidance of sharing towels and linen may help reduce the spread of infection at home. Generally, if your child is in day care or school, keep him or her home until the eyes are significantly improved and the drainage is gone.
Remember, it is not a good idea to place previously opened medicines or someone else's medication into your child's eye. It can cause complications, infections, and prolonged symptoms. Always check with your doctor before using any medication for the eyes.
Conjunctivitis is, for the most part, not a serious condition. Always see your doctor so that a proper diagnosis can be made, and that timely and appropriate treatment can be started. Early treatment will hasten your child's return to school and activities. It will also prevent unwanted complications.
