Nasolacrimal Duct Obstruction | Symptoms and Causes

When you have a blocked tear duct (nasolacrimal duct obstruction), your tears can’t drain properly, leaving your eye watery and irritated. This condition occurs when there is a partial or complete blockage in the tear drainage system. It is almost always treatable, and the choice of treatment depends on the underlying cause of the blockage and on your age.

Causes of Nasolacrimal Duct Obstruction

The most common cause is the failure of the thin membrane at the end of the tear duct to open normally. In adults, a blocked tear duct may result from trauma, infection, or a tumor. Blocked tear ducts are very common in newborns, but they usually improve on their own during the first year of life without any intervention.

Nasolacrimal duct obstruction can occur at any age.
