Blocked Tear Duct – dacryostenosis
A blocked tear duct is a partial or complete blockage in the system that carries tears away from the surface of the eye into the nose.
A tube called the nasolacrimal duct normally drains tears from the surface of the eye into the nose. If this duct is blocked, the tears will build up and overflow onto the cheek, even when a person isn’t crying.
In adults animals, the duct can be damaged by infection, injury, or a tumour.
signs and symptoms:
The symptom is increased tearing, which overflows onto the face or cheek.
