The human eye is a marvel of biological engineering, designed not only to capture light but to maintain its own surface health through a constant circulation of tears. Every time we blink, a fresh layer of tears spreads across the eye, providing lubrication and protection. Under normal circumstances, these tears drain into the nose through a complex network of channels known as the lacrimal drainage system. However, when this drainage system becomes obstructed—a condition known as a blocked tear duct—tears cannot drain properly, resulting in excessive watering, irritation, and potential infection. While a blocked tear duct can be a nuisance, understanding its causes and treatments allows patients to navigate the path from discomfort to relief.
The most effective non-surgical method for unblocking a tear duct in both infants and adults is a specific type of massage called the . This uses gentle pressure to increase hydraulic pressure in the tear sac, forcing the blockage open. how to unblock a tear duct
However, when home remedies fail or if an infection develops, medical intervention becomes necessary. If the blockage is caused by swelling or infection, an ophthalmologist will typically prescribe antibiotic eye drops or ointment to clear the infection. Once the inflammation subsides, the duct may open on its own. Additionally, if the blockage is due to allergies or sinus issues, nasal decongestants or steroid sprays may be used to shrink the surrounding tissues and relieve the pressure on the duct.

For many babies, the duct clears on its own by age one, but you can speed up the process at home. Tear-Duct Blockage | Nemours KidsHealth This uses gentle pressure to increase hydraulic pressure
That persistent watering eye, the recurring crustiness, or a blob of mucus in the corner of your vision—these are the hallmark signs of a blocked tear duct. Medically known as nasolacrimal duct obstruction, this condition prevents tears from draining normally through the small channel that runs from the inner corner of your eye into your nose.
