Causes of Watering Eyes

In a normal eye, there is a sac that drains tears from our eyes to our nose. This is called the naso-lacrimal sac. Blockage of this sac is among the commonest causes for watering from the eyes. If this blockage is left unattended, tears collect in the sac. They can get infected, causing pain, swelling and redness in the area of the sac and the lower lid. Sac syringing is a test to confirm this blockage in which saline is injected through the opening of the sac near the eyes (punctum). If this fluid easily and completely empties in the nose, the path is considered patent. Amount of regurgitation of fluid can be documented by the doctor to determine if there is a partial or complete blockage and to determine the site of blockage. Surgical correction by creating an alternative passage for drainage of the fluid from the sac to the nose is the definitive treatment.
