A Pilot Nonrandomized Controlled Trial Examining the Use of Artificial Tears on the Radioactivity of Tears after Radioactive Iodine Treatment for Thyroid Cancer

CONCLUSIONS: I-131 is present in the tears following RAI therapy for thyroid carcinoma. Frequent PFATs starting on the day of RAI ingestion may decrease the level of I-131 in the tears. This finding could have implications for lowering the risk of NLDO. Future multi-center clinical trials are needed to determine if the use of artificial tears after RAI therapy may decrease the risk of NLDO.CLINICAL TRIAL REGISTRATION: NCT04327999.PMID:37917111 | DOI:10.1089/thy.2023.0338
