The Dacryocystitis - Inflammation of the tear sac, usually resulting from the blockage of the tear duct. The condition sometimes occurs in infants if the tear duct has not developed normally. In adults, it may follow inflammation in the nose or an injury. The cause is often unknown.

Symptoms include pain, redness, and swelling between the inner corner of the eyelids and the nose. Infection may occur and cause a discharge.
