Background: Epiphora is a condition in which an overflow of tears occurs because of excessive lacrimal secretion or insufficient drainage of tears due to obstruction of the nasolacrimal system. This ophthalmic complication can be an intermediate to late sequela of radioactive iodine (131I) therapy in thyroid cancer patients. Patient Findings: We present a case of a 23-year-old woman with complaints of bilateral excessive tearing 6 months after 131I therapy for well-differentiated thyroid cancer. She was diagnosed with epiphora secondary to nasolacrimal duct obstruction (NDO) and had bilateral endoscopic dacryocystorhinostomy, which resulted in complete resolution of her symptoms. Summary: The sodium iodide symporter, present in cells of the lacrimal drainage system, is the potential mechanism by which 131I therapy can cause inflammation, fibrosis, and ultimate obstruction of tear outflow. Risk factors such as 131I dose, female sex, older age, and anatomical variations may also play a role in the obstruction. However, the precise pathophysiologic mechanisms remain incompletely understood. Conclusions: NDO is an under-recognized complication of 131I therapy in thyroid cancer patients. Questions regarding eye symptoms should be an integral part of clinical follow-up in management of such patients so that effective intervention may be performed. [ABSTRACT FROM AUTHOR] |
