Abstract

With dry eye syndrome a deficient amount of liquid film on the surface of the cornea causes the epithelium to become dry between blinks. Physiologically, tearing and mucus secretion decrease with age, but such decreases also can occur in young people. With Sjögren syndrome—often associated with connective tissue disorders, particularly rheumatoid arthritis— symptoms may include dry eyes, dry mouth and nose, and gastric hyposecretion. Dry eyes also often occur with xerophthalmia, a vitamin A deficiency that is a common cause of blindness worldwide. Other etiologies of the dry eye syndrome include abnormal eyelid positions or deficient blinking reflexes. In addition to dry eyes, this syndrome may present other intermittent, nonspecific symptoms such as burning, pain, photophobia, itching, and a “gritty” sensation. Physical findings include hyperemia and a convex-shaped tear meniscus less than 1 mm in height.
