Tear duct (health)


Part of the drainage system for the tears. The dilated part of the tear duct is called the lacrimal sac. An obstruction along the tear duct in infancy will cause a watery or draining eye. A warm compress is sometimes used to open a blocked tear duct. A tear duct probing surgery may be necessary to relieve the blockage.
