Causes of Blocked Tear Duct

Most of the tears are formed by the lacrimal glands, which are located above each eye. The tears flow down the surface of the eye to lubricate and protect it and then drain into the tear duct system through an opening (lacrimal punctum) located at the corners of the upper and lower eyelids. The tears eventually drain into the nose through the naso-lacrimal duct. A partial or complete blockage of the tear drainage system causes dacryostenosis.


Obstruction of the tear duct is caused by -

  • Congenital abnormality - Many children are born with an underdeveloped tear-duct system or there may be a duct abnormality. Almost 20% of newborns are affected by this condition at birth.
  • Bacterial infection of the duct
  • Sinus or nasal infection, especially the long standing infections

Dear Pat, I have now also got a blocked tear duct and have been told by my doctor that what you had is able to be done easily with no pain. Did you have a sinus infection before it happened that caused it? only one eye is affected and yes I have a sinus infection.

My eye doctor stretched the opening-inserted what felt like a needle & irrigated the duct w/salt water. It did hurt briefly, but it did open the duct up. Eye drops 3X daily followed...so far so good.
