Keratoconjunctivitis is a condition in which 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 2 main reasons that keratoconjunctivitis sicca occurs:

  • The eye no longer makes enough tears to keep the surface moist and the eye dries out.
  • The eye does make enough tears, but they evaporate too quickly. The tears produced are of poor quality and are unable to coat the surface of the eye.
