Blocked Tear Duct / Dacryostenosis
A blocked tear duct or dacryostenosis is a partial or complete obstruction in the tear drainage system i.e. the pathway that carries tears from the surface of the eye into the nose.
This is a common condition affecting newborns. In infants, there may be a partial or complete blockage of the tear duct system, which can be seen by continual overflow of tears from the eye. Gradually this condition changes on its own before the child is 1 year old.
Adults can get a blocked tear duct due to infection, inflammation, eye injury or a tumor. It occurs more often in older people with eye infections. Treatment with antibiotics is needed in this case.
A blocked tear duct is almost always correctable, but the treatment depends on the cause and age of the patient. Treatment options vary from massage of the lacrimal duct area to minimally invasive procedures like saline water irrigation or probing. Surgery is performed in cases where conservative treatment fails.
