Recruiting studies
- NCT07154121Recruiting
5-FU added to tear duct surgery for small tear sacs
This study tests if adding a medicine called 5-FU to standard tear duct surgery helps people with a small tear drainage sac get better results. It might be an option if you have a blocked tear duct and a very small sac.
Guangzhou, GuangdongAges 18 years+ - NCT07225244Recruiting
Comparing balloon inflation points for tear duct surgery
This trial tests whether using four balloon inflation points during tear duct surgery works better than the standard two points for people with blocked tear ducts. It aims to improve tear drainage and reduce symptoms.
TaipeiAges 20 years+ - NCT05999630RecruitingPhase 3
Artificial tears to prevent tear duct blockage during RAI therapy
This study tests if using artificial tears (eye drops that keep your eyes moist) can prevent tear duct blockage in people receiving high-dose radioactive iodine for thyroid cancer. If you qualify, you will use artificial tears during your treatment to see if they help keep your tear ducts open.
Nashville, TennesseeAges 18 years+ - NCT06530264Recruiting
Comparing methods for tear duct surgery
This trial compares different ways to manage the flap during external dacryocystorhinostomy (a surgery to clear blocked tear ducts). It may help if you have a blocked tear duct, a tear sac infection or a tear sac cyst or fistula.

Common questions
- Are there clinical trials for nasolacrimal duct obstruction?
- Yes. Clin2 currently lists 4 recruiting nasolacrimal duct obstruction studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a nasolacrimal duct obstruction trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a nasolacrimal duct obstruction trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
