Tearing in the elderly, if caused by conjunctivitis, trachoma, keratitis, inverted eyelashes, or obstruction of the lid gland, can be resolved with eye drops, eyelash removal, and lid gland massage. In addition, there is another type of tear duct disease, such as narrowing of the tear duct opening, which can be resolved by dilating the tear duct opening. Those with tear duct obstruction are determined by flushing the tear ducts and can be treated with surgery or laser.
