Adult patients with epiphora attending a tertiary lacrimal clinic from May 2010 to April 2021 were reviewed. Cases with evidence of soft stop encountered during lacrimal syringing\/probing were included, and patients with possible canaliculitis or a history of lacrimal surgery were excluded.

The mean age of the patients was 63.8\u2009\u00b1\u200915.6 (range 28\u201387) years, and 27 (65.9%) were females. Intraoperative examination findings were available for 27 of 30 cases that underwent lacrimal surgery and DCG was available for 40 systems. Pre-sac obstruction found on syringing\/probing was confirmed in 40% and 37% of cases on DCG and surgery, respectively. The correlation between syringing\/probing and DCG was stronger for canalicular than for common canalicular location (<jats:italic>p<\/jats:italic>\u2009=\u20090.016). Canalicular stenosis on syringing\/probing manifested as pre-sac abnormality on DCG in 5\/7 (71.4%) compared to 0\/6 common canalicular stenosis cases (<jats:italic>p<\/jats:italic>\u2009=\u20090.021). Based on the surgical findings, the false-positive rate of a soft stop on syringing\/probing was highest for common canalicular \u2018stenosis\u2019 (100%) and lowest for canalicular \u2018block\u2019 (45.5%;<jats:italic>p<\/jats:italic>\u2009=\u20090.093).
