xerophthalmia









































xerophthalmia (from ancient greek xērós (ξηρός) meaning dry and ophthalmos (οφθαλμός) meaning eye) is a medical condition in which the eye fails to produce tears. it may be caused by vitamin a deficiency, which is sometimes used to describe that condition, although there may be other causes.









































xerophthalmia caused by a severe vitamin a deficiency is described by pathologic dryness of the conjunctiva and cornea. the conjunctiva becomes dry, thick and wrinkled. if untreated, it can lead to corneal ulceration and ultimately to blindness as a result of corneal damage.
