Watery Eyes? Could It Be a Blocked Tear Duct?

There are many causes for watery eyes, and one of them is a blocked tear duct. Tear ducts, also known as puncta, are located at the inner corners of the eyes and are responsible for draining excess tears. When the puncta become blocked, tears cannot flow properly, and they remain on the surface of the eyes, eventually spilling onto the face. This blockage may be partial or complete, leading to an overflow of tears, a condition known as epiphora.

Additional Symptoms of a Blocked Tear Duct

Other symptoms associated with a blocked tear duct include blurred vision, blood mixed with tears, mucus discharge, conjunctivitis, and other eye infections. Swelling and pain may also occur. The blockage can happen at any part of the tear duct system, including the canaliculi, the canal that carries tears to the nose.

Causes of Tear Duct Blockages

There are several possible causes for this blockage. One cause is congenital defects, such as duct abnormalities or Down syndrome. Sometimes, the nasolacrimal duct tissue itself may contribute to the problem. Aging is another factor; as we grow older, changes in eye shape can lead to blockages in the puncta. Cancerous tumors, facial injuries, cartilage or bone damage, mucus buildup, and inflammation can also obstruct the ducts. Additionally, certain medications, like eye drops or chemotherapy, may cause tear duct obstruction.

If left untreated, a blocked tear duct can lead to complications. Tears need to flow freely, and stagnation can increase the risk of infection. Viruses may infect the area, worsening the issue, and in severe cases, vision loss can occur. If you experience watery eyes, it’s best to consult an ophthalmologist for appropriate treatment. The course of treatment depends on the underlying cause, and in some cases, minor surgery may be necessary to unblock the tear duct system.
