Although serious adverse effects are infrequent, complications such as dry mouth, sialadenitis, and dysphagia have been described. The involvement of the eyes and accessory visual structures is not commonly discussed, despite dry eye, keratoconjunctivitis, and lacrimal system obstruction (LSO) being reported, especially after high cumulative doses of radiopharmaceuticals. The incidence of LSO is not well established.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives:<\/jats:title>\n                    <jats:p>The aim of this study was to determine the frequency of LSO in patients undergoing RIT at 2, 4, 6, and 12 months after treatment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Patients with differentiated thyroid carcinoma undergoing (group 1) and not undergoing (group 2) RIT were evaluated in the preoperative and postoperative periods and 2, 4, 6, and 12 months post surgery or post RIT.
