Artificial tears to prevent tear duct blockage during RAI therapy
Part of Cancer, Eyes & vision, Hormones & metabolism clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You are receiving radioactive iodine (RAI) therapy for thyroid cancer, with a dose of at least 150 mCi.
- You do not use any prescription eye drops (except artificial tears).
- You have no history of eye injury, tear duct infection, radiation therapy, or chemotherapy with certain drugs (like 5-fluorouracil or docetaxel).
- You do not have medical conditions that cause tear duct blockage (such as sarcoidosis, granulomatosis with polyangiitis, or chronic lymphocytic leukemia).
- You do not already have a blocked tear duct.

This trial studies how well radioactive iodine treatment works for people with certain types of thyroid cancer that have a low or intermediate risk of coming back. It aims to see if this treatment is effective and safe for these patients.
This study tests a surgery called dacryocystorhinostomy (DCR) that creates a new tear drainage path to stop watery eyes. The surgery is done without a stent (a small tube), and the goal is to relieve symptoms of blocked tear ducts.
This study compares two ways to treat a blocked tear duct in babies: gentle massage of the tear sac area versus a quick probing procedure. It aims to find which method works better to clear the blockage and reduce watery eyes.
This trial offers a decision aid to help you choose whether to have radioactive iodine (RAI) treatment after thyroid cancer surgery. You may qualify if you have intermediate-risk thyroid cancer and haven't yet made a decision about RAI.
This study compares two treatments used during a surgery to unblock the tear duct. The goal is to see which one helps keep the duct open longer and reduces the chance of the blockage returning.
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.
