It has been demonstrated that radioactive iodine therapy (RIT) is very useful for ablating remnant thyroid tissue or metastatic lesions after total thyroidectomy in well-differentiated thyroid cancer. Epiphora as a result of lacrimal drainage system obstruction is a rare complication of RIT. Previous studies have shown that most patients with epiphora after RIT are old ages, females, and with high cumulative radioactive iodine dose. Here, we report on a case of epiphora with low-risk factors including young ages, male, and 5.5-GBq (150-mCi) dose in the first RIT.
