Keratoconjunctivitis sicca (KCS) is a Latin medical term used to describe a condition of decreased tear production. The term technically means "inflammation of the cornea and conjunctiva from drying." When the watery part of the tears is not produced in adequate amounts, the eye becomes chronically inflamed, and scarring and pigmentation of the cornea may lead to a decrease in vision. Another commonly used term to describe this disease is "dry eye."Numerous breeds of dogs are at risk for developing KCS including the West Highland white terrier, English bulldog, pug, shih tzu, American cocker spaniel, Lhasa apso and Pekingese.If left untreated, KCS is a potentially vision threatening disease. It may lead to painful corneal ulcerations in the acute stage of the disease. In chronic KCS, vision may be impaired because of scarring of the cornea.
