Sac Syringing

Sac syringing is a simple, safe procedure used to check whether the tear drainage system in your eyes is working properly. By gently flushing a small amount of saline (salt water) through the tear duct, eye specialists can determine if there is a blockage and where it is located. It is also sometimes used to clear mild obstructions or debris from the tear passages.

This quick outpatient procedure helps guide further treatment for patients experiencing excessive tearing or eye irritation.

Why is it done?

Sac syringing is recommended to:

Investigate Excessive Tearing (Epiphora): When your eyes water persistently, the test helps check for blockages in the tear ducts.
Diagnose Tear Duct Blockages: It identifies where and how severe the blockage is, which guides the next steps in treatment.
Monitor Post-Surgical Healing: After tear duct or nasal surgery, this test ensures that the tear drainage pathway remains open.

This procedure is important for both adults and children, especially those with recurring eye watering or infection.

What to Expect During the Sac Syringing Procedure

Preparation: Your eye will be numbed with anesthetic eye drops to ensure comfort.
Cannula Insertion: A fine, blunt-tipped cannula (attached to a syringe) is gently inserted into the tear duct opening (punctum) near the inner corner of the eyelid.
Saline Injection: A small amount of sterile saline is slowly injected into the tear duct.
Observation: Your eye specialist observes the flow. If the saline comes out of the nose or is tasted in the throat, the passage is likely clear. If it flows back or causes discomfort, a blockage may be present.

The procedure takes about 5–10 minutes and does not typically require recovery time.
