What is a blocked tear duct?

Also known as: dacryostenosis.

The tear duct (nasolacrimal duct) is the tube that carries tears from the corner of the eye to the nose. Blockage (occurring in up to 10% of newborn babies and in 30% of children blockage happens on both sides) prevents tears from lubricating the eye properly or draining normally.
