Keratoconjunctivitis sicca (KCS), also called keratitis sicca,sicca syndrome, xerophthalmia, dry eye syndrome (DES), or simply dry eyes, is an eye disease caused by decreased tear production or increased tear film evaporation commonly found in humans and some animals

Dry eye syndrome often occurs in people who are otherwise healthy. It is more common with older age, because you produce fewer tears with age. In rare cases, it can be associated with rheumatoid arthritis, lupus erythematosus, and other similar diseases. It may also be caused by heat (thermal) or chemical burns. In areas of the world where malnutrition is common, vitamin A deficiency is a cause. This is rare in the United States.


There is no way to prevent dry eye syndrome. You can prevent complications by using wetting and lubricating drops and ointments.


Most patients with dry eye have only discomfort, and no vision loss. With severe cases, the clear window on the front of the eye (cornea) may become damaged or infected.


Treatments may include: * Wetting drops called artificial tears * Lubricating ointments (in more severe cases) * Tiny plugs placed in the tear drainage ducts to help the tears stay on the surface of the eye * Medications such as Restasis, topical corticosteroids, and oral tetracycline and doxyccycline Surgery may be used if the eyelids are in an abnormal position.
