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 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 for blocked tear ducts in babies: a special eyelid massage versus a gentle probe opening (probing) with a local anesthetic cream. It helps find out which approach works better and is less stressful.
This study looks at how well radioactive iodine therapy works for patients with certain types of thyroid cancer that are considered low or intermediate risk. It may help you understand if this treatment is right for you.
This trial tests a new light-activated gel to help keep the tear duct open after standard surgery. It may reduce the chance of the duct closing again.
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.
This study compares two medications (hyaluronic acid and mitomycin-C) used during a surgery to open a blocked tear duct. It aims to see which one helps the new tear channel stay open longer, especially for people with chronic eye discharge or tearing.
