Clinical expansion
A clinical overview of endoscopic tear-drainage surgery for selected monocanalicular obstruction.
Obstruction of a single canaliculus can cause tearing, discharge, or recurrent irritation and may require treatment beyond office-based probing.
Who may read this information: Patients with persistent unilateral tearing and a confirmed lacrimal drainage obstruction.
How the technique is considered: An endoscopic dacryocystorhinostomy creates a pathway between the lacrimal drainage system and the nose without relying on a large external skin incision. The method is selected after testing the drainage anatomy.
Understanding monocanalicular obstruction
The lacrimal drainage system is a connected pathway. An isolated obstruction can be difficult to localize without examination and testing.
Symptoms may overlap with ocular surface irritation, so the workup considers both drainage and tear-film health.
Endoscopic treatment
An endoscopic approach is planned around the obstruction and nasal anatomy. Dr. Mancini reviews alternatives, stents, expected recovery, and the possibility of persistent symptoms before treatment.
Potential benefits and limitations
- Uses an endoscopic route in selected cases
- Addresses tear drainage at the level of the lacrimal sac and nose
- Can be planned with other lacrimal procedures when needed
Limitations: Endoscopic DCR is not appropriate for every obstruction and does not guarantee complete resolution of tearing.
Recovery: Nasal congestion, mild bleeding, swelling, or temporary tearing can occur. Follow-up is used to assess healing and maintain the drainage pathway when a stent is used.
Consultation: The consultation includes lacrimal history, irrigation, nasal examination, and discussion of prior procedures.
Questions patients ask
Frequently asked questions
What causes persistent tearing?
Tearing may be caused by a blocked drainage system, eyelid malposition, inflammation, or ocular surface irritation. Testing helps identify the contributing factor.
