Dry Eye Syndrome

By Judith Lee and Gretchyn Bailey, with contributions by Shereen Jegtvig, Certified Nutrition Specialist (CNS); reviewed by Vance Thompson, MD

Dry eye syndrome is a chronic lack of sufficient lubrication and moisture on the surface of the eye.

Its consequences range from subtle but constant irritation to ocular inflammation of the anterior (front) tissues of the eye.

Dry eyes also are described by the medical term, keratitis sicca, which generally means decreased quality or quantity of tears. Keratoconjunctivitis sicca refers to eye dryness affecting the cornea and conjunctiva.

Dry Eye Syndrome Symptoms

Persistent dryness, scratching and burning in your eyes are signs of dry eye syndrome. These symptoms alone may prompt your eye doctor to diagnose dry eye syndrome.

But sometimes your eye doctor may want to measure the amount of tears in your eyes. A thin strip of filter paper placed under the lower eyelid, called a Schirmer test, is one way to measure tear production.

Another symptom of dry eyes is a "foreign body sensation," the feeling that something is in the eye.

And it may seem odd, but sometimes watery eyes can result from dry eye syndrome, because the excessive dryness works to overstimulate production of the watery component of your eye's tears.
