A passage through which tears pass from the lachrymal glands to the eye or from the eye to the nose.
- ‘A thin, blunt metal wire is gently passed through the tear duct to open any obstruction.’
- ‘Viruses and bacteria may be rubbed into the eye or may travel from an infection in the nose up through a tear duct and into the eye.’
- ‘Some children have nasal polyps, which are cysts or growths of extra tissue in the nose at the end of the tear duct.’
- ‘Before massaging the tear duct, wash your hands.’
- ‘This can be caused by a blocked tear duct, which can be treated by gentle massage between the eye and nasal area.’
