xerophthalmia 

Extreme dryness of the conjunctiva and cornea due to a failure of the secretory activity of the mucin-secreting goblet cells of the conjunctiva. The conjunctiva and cornea lose their lustre and become skin-like in appearance. The condition may even propagate to the cornea and give rise to keratoconjunctivitis sicca and, if severe, keratomalacia. Xerophthalmia may be due to trauma, exposure or systemic deficiency of vitamin A, etc. Syn. xeroma; xerosis of the conjunctiva (if the cornea is not involved). See keratoconjunctivitis sicca; keratomalacia; mucin; Bitot's spot.
