Xerosis of the conjunctiva ( ONE OF THE SYMPTOMATIC CONDITIONS OF CONJUNCTIVA) is a symptomatic condition in which conjunctiva becomes dry and lustreless. Normal conjunctiva is kept moist by its own secretions, mucin from goblet cells and aqueous solution from accessory lacrimal glands. Therefore, even if the main lacrimal gland is removed, xerosis does not occur. Depending upon the etiology, conjunctival xerosis can be divided into two groups, parenchymatous and epithelial xerosis.
1. Parenchymatous xerosis. It occurs following cicatricial disorganization of the conjunctiva due to local causes which can be in the form of (i) widespread
destructive interstitial conjunctivitis as seen in
