Dacryocystitis

Inflammation of the tear sac, usually resulting from blockage of the tear duct. The condition may occur 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. The obstruction may be cleared by flushing the tear duct with saline. Antibiotic eye-drops or ointment are given for infection. In infants, massaging the tear sac may clear a blockage. Surgery to drain the tear sac (called dacryocystorhinostomy) is occasionally necessary.
