Inflammation of the tear sac, often resulting from the blockage of the tear duct. If the tear duct has not developed normally the condition can also affect infants. Adults usually contract the condition following an injury or inflammation of the nose. The cause is generally unknown.
Symptoms include redness, swelling and pain, between the inner corner of the eyelids and nose. Infection can arise and cause a discharge.
The obstruction can be cleared by flushing the tear duct with saline. Ointment or antibiotic eye drops are given for the infection. In children, massaging the tear sac can clear a blockage. Surgery to drain the tear sac (dacryocystorhinostomy) is sometimes necessary.
