Syringing of Lacrimal System
About the procedure
Syringing of the lacrimal system involves irrigating the tear drainage pathways to assess their patency and sometimes mechanically relieve obstruction. It is performed under topical anaesthesia by inserting a cannula through the punctum and flushing saline. Patency is confirmed if fluid reaches the nose or by observing reflux. The procedure helps investigate epiphora (excess tearing) and may partially treat nasolacrimal duct obstruction. Additional imaging, like dacryocystography or endoscopic assessment, may be indicated for persistent blockages. Recovery is minimal, with monitoring for infection recommended.
Care before the procedure
- Avoid applying eye makeup or creams on the day of the procedure.
- Inform the doctor about any eye infections or medications.
- Note the history of chronic tearing or prior lacrimal surgery.
- Arrange tissues or assistance, as some reflux of fluid may occur.
Care during the procedure
- Sit still and keep eyes open as instructed during cannula insertion.
- Follow instructions to tilt head or move slightly for optimal irrigation.
- Notify the examiner if sudden pain or discomfort occurs.
- Breathe normally and remain relaxed during saline flushing.
Care after the procedure
- Avoid blowing your nose immediately after the procedure to prevent reflux.
- Mild watery eyes or irritation may occur temporarily.
- Monitor for signs of infection, like redness or increased discharge.
- Resume normal activities unless instructed otherwise by the doctor.
Eligibility
- Patients with chronic tearing (epiphora) needing assessment of tear drainage.
- Individuals suspected of nasolacrimal duct obstruction or partial blockage.
- People with recurrent eye infections related to tear stagnation.
- Patients requiring follow-up after previous lacrimal surgery or stent placement.
