Слезотечение у пациентов после высокодозной терапии радиоактивным йодом

Abstract

Purpose. To estimate the frequency of tearing in patients after high-dose radioiodine therapy. Materials and Methods. The survey was conducted in 500 patients after radioiodine therapy (group 1) and 654 volunteers (group 2). We asked whether the respondent noticed epiphora last month, in case of a positive answer we specified how many times during the day it was necessary to wipe the tear, comparing the result with Munk scale. Results. The patients of group 1 noticed tearing in 232 cases, the respondents of group 2 noticed it in 186 cases. Epiphora was more frequent in patients of group 1 (46 % of cases), rather than in volunteers of group 2 (27 % of cases). Excessive tearing was noticed in 8.8 % of patients of group 1 and 3.5 % of respondents of group 2. The difference was statistically significant. Conclusion. 8.8 % of patients complain about excessive tearing after high-dose radioiodine therapy, which is more frequent than in the general population. This may be related to secondary acquired nasolacrimal duct obstruction. Key words: epiphora, nasolacrimal duct obstruction, radioiodine therapy.
