keratoconjunctivitis sicca

Dry eye. A state of inadequate wetting and lubrication of the cornea as a result of defective tear production. This results from damage to the tear glands by the same AUTOIMMUNE DISEASE process that causes RHEUMATOID ARTHRITIS, SJOGREN'S SYNDROME, systemic lupus erythematosus and other related conditions. Dry eye is common in all these disorders. There is constant discomfort, foreign-body sensation and sometimes pain and the condition may progress to infection and ulceration of the cornea. Treatment is by the regular use of artificial tears.
