- 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.
