The purpose of this study was to evaluate the correlation between the lacrimal syringing test (LST) and dacryoscintigraphy (DSG) in patients with epiphora. The authors retrospectively reviewed the clinical records of patients who underwent both LST and DSG from March 2016 to February 2018. From this, 636 eyes of 336 patients with a mean age of 61.20 ± 11.93 years (range, 22-86 years) were included. The concordance rate between LST and DSG was 43.7% (278 eyes). The sensitivity of DSG was 68.78%, and specificity was 30.99%. Factors of age and sex were analyzed in terms of concordance. The authors categorized age into 2 groups of younger and older than 65 years. Only sex was found to affect the results, with a much higher concordance rate in the female group than the male group. The lack of correlation between the tests indicates that the LST and DSG methods are complementary to each other. There is no single reliable method for testing patency of the lacrimal drainage system. Therefore, physicians should refer to these tests as complementary in a clinic setting.
