Dry eye syndrome is caused by a chronic lack of sufficient lubrication and moisture on the surface of the eye. The effects of dry eyes range from fine but permanent ocular irritation to significant inflammation and even scarring on the anterior surface of the eye. Besides being called dry eye syndrome, dry eye disease or simply "dry eye," the alternative medical terms used to describe dry eyes include :
Keratitis sicca : - is commonly used to describe dryness and corneal inflammation.
Kerato conjunctivitis sicca :- Used to describe the dry eye, which affects both the cornea and the conjunctiva.
Dysfunctional tear syndrome :- Used to emphasize that inadequate tear quality can be as important as insufficient quantity.
