• Dry eye syndrome is caused by a chronic lack of sufficient lubrication and moisture on the surface of the eye.
  • Consequences of dry eyes range from a subtle but constant eye irritation to significant inflammation and even scarring of the front surface of the eye.
  • Alternative medical terms for dry eye disease or simply “dry eye,”:
    • Keratitis sicca: generally used to describe dryness and inflammation of the cornea.
    • Keratoconjunctivitis sicca: used to describe dry eye that affects both the cornea and the conjunctiva.
    • Dysfunctional tear syndrome: used to emphasize that inadequate quality of tears can be just as important as inadequate quantity.
