Blocked Tear Duct And Its Causes
It is a condition in which the eyes drain system, that produces tears is totally or partially blocked. Due to this condition there is no normal drain in the eyes. The eyes also get watery and irritating. Sometimes it also gets infected.
The lacrimal glands are responsible for producing tears. They are located above our eyes. Tears are very helpful to lubricate and protect our eyes. These tears finally drain into the puncta, which is the tiny hole present at the corner of our lower and upper eyelids. Then they travel through small canals which is present in the lids to a sack present near the nose and finally through nasolacrimal duct and empty into the nose. Finally they get evaporated or reabsorbed.
It is estimated that nearly 20% newborn babies suffer from blocked tear duct. But this condition resolves on its own within 6 months. Tear duct blockage can result from swelling, injury or a tumor.

There are various causes for a blocked tear duct. It can happen anytime and one may have inflammation, eye infection or watery eyes. Chronic nose infection is also another cause of a blocked tear duct. Chronic sinusitis irritates the tissues and forms scars leading to tear duct blockage. Some of the other causes are abnormal development of skull, which increases the likelihood of tear duct blockage. Age-related changes narrow down the punctal opening. A broken nose can also block tear ducts. Nose polyps can also block the tear ducts. Sometimes conjunctivitis can also block the tear duct. Some viral infections can also block the tear duct.
