Blocked Tear Duct

Alternate Names : Occlusion of Nasolacrimal Duct

Blocked Tear Duct | Symptoms & Signs | Diagnosis & Tests | Prevention & Expectations | Treatment & Monitoring

How is the condition diagnosed?

Diagnosis of a blocked tear duct begins with a history and physical exam. When there is constant tearing and discharge in one or both eyes, a blockage is suspected. In an adult, frequent watering or infections can be signs of a blocked tear duct.

A healthcare provider can confirm the diagnosis by trying to rinse the nasolacrimal system. A small tube is placed into the opening on the lower lid. Then fluid is channeled into the nose. If it does not flow into the back of the nose, and the person cannot taste it going down the throat, a blocked tear duct is diagnosed.
