Conjunctivitis

Often called "pink eye" or "red eye," conjunctivitis is a painful and/or itchy redness of the whites of one's eyes. It is most commonly due to an allergic reaction or an infection (usually bacterial, but sometimes viral). This is different from bleeding into the white part of one eye, called a "subconjunctival hemorrhage," which leaves part of 1 eye bright red, but causes no pain or vision change. Though it looks nasty, this goes away on its own and is not dangerous. It is more common in diabetes and high blood pressure (so check for these if it happens), but most often happens in healthy people.

Conjunctivitis can be caused by:

  • Allergies — Itching is the dominant symptom. It is more likely to affect both eyes, and the discharge/watering from the eyes is usually clear. It may hit suddenly, or be mild and ongoing.
  • Viral — Though there may be some itchiness, the pain, mild redness (more pink) and watering are more prominent. It may start in 1 eye, but easily can spread to the other (so be careful not to touch the unaffected eye). The discharge is usually clear and watery. It may take 3 weeks to resolve and may occur along with a respiratory infection or cold.
  • Bacterial — This is associated with a puss-like yellow-green mucus discharge along with pain.
  • Toxic — From an acute chemical exposure (usually obvious and should be immediately addressed).
  • Falling asleep with your contact lenses in or having inadequate tears to support the use of contact lenses.

Though the viral and allergic conjunctivitis tend to be benign and resolve on their own, it is best to see an eye doctor to rule out bacterial conjunctivitis or more dangerous viral infections of the cornea. Seeing an eye doctor is especially important if you have yellow discharge or severe pain or light sensitivity in the eye, or the pupil (black part of the eye) is irregularly shaped instead of round.

Therapy

Once the eye doctor has ruled out and addressed more worrisome causes, therapy is for symptom relief. Cool compresses or rinses can help itching and warm compresses help pain. If only 1 eye is involved, be sure to tilt your head to the side so the affected eye is lower than the healthy eye. Otherwise, if water flows from the infected eye to the other eye, it may also get infected. Antihistamines can also help with itching. Benadryl, which is sedating, is best at night so you can sleep. A non sedating antihistamine is best during the day (e.g., Claritin or Zyrtec). For long term allergic conjunctivitis, addressing allergies with the supplement MSM (3,000+ mg a day) and/or a special acupressure technique called NAET (see www.NAET.com) can be helpful. But these take longer to work.

For contact lens and dry eye induced conjunctivitis, using special eye drops containing vitamin A can be very helpful over time.
