Pronounced: Kera-to-con-JUNK-tiv-eye-tis sick-ahEn Español (Spanish Version)
Keratoconjunctivitis is a condition in which the the membranes on the surface of the eye known as the conjunctiva become red and inflamed. The most common form of this condition is keratoconjunctivitis sicca. This occurs when the surface of the eye becomes dry due to a lack of quality tears.

There are two main reasons that keratoconjunctivitis sicca occurs. The first is that the eye no longer makes enough tears to keep the surface moist, and the front surface of the eye dries out. Alternatively, the eye does make enough tears, but they evaporate too quickly. In this case, the tears produced are of poor quality and are unable to coat the surface of the eye.
