Medical Definition of Dacryostenosis
1. A blocked nasolacrimal duct which normally carries tears from the eyes to the nose.
Commonly seen in infants, but usually resolves spontaneously by age 2-3. In adults blockage can occur from chronic sinusitis or trauma. A gentle massage of the lacrimal gland 2-3 times a day for several months may reopen the tear duct.
