Blocked tear duct

Dacryostenosis; Blocked nasolacrimal duct; Nasolacrimal duct obstruction (NLDO)

A blocked tear duct is a partial or complete blockage in the pathway that carries tears from the surface of the eye into the nose.

Blocked tear duct

Tears are produced by the lacrimal gland located in the upper outer portion of each eye. Tears drain into a tear duct through a very small opening in the corner of your eye, near your nose. This opening is called the nasolacrimal duct. If this duct is blocked, the tears will build up and overflow onto the cheek.
