AIM:To explore the clinical outcomes of RS lacrimal tube for lacrimal canaliculi rupture without nasal endoscope.

METHODS:A retrospective analysis from September 2017 to March 2018 were taken. According to admission time sequence. Totally 52 patients with lacrimal canaliculi rupture was divided into two groups. One group was treated with RS lacrimal tube, the other was treated with annular silicone tube. The treatment results were comparatively analyzed.

RESULTS:There were 15 eyes of nasal mucosa hemorrhage in annular silicone tube group. There was no eye with this in RS tube group, the difference between the two groups was significant(P<0.001). In RS tube group, 26 eyes were cured, 3 eyes improved, 3 eyes failed. The effective rate was 91%. In annular silicone tube group, 15 eyes were cured, 3 eyes improved, 2 eyes failed. The effective rate was 90%, the clinical efficacy was not significantly different between groups(P=0.877). There were 2 eyes in RS tube group occurred fall off in 2wk to 2mo after operations; 1 eye of lacrimal puncture were removed from the lacrimal puncture without 2wk, and was anastomosed again. The other eye was removed from the lacrimal puncture within 1-2mo after the operation, the lacrimal canal flushing was improved during follow-up. There were 3 eyes in annular silicone group occurred fall off without 2wk, and were not anastomosed again. The lacrimal duct flushing was improved during follow-up. No statistical significance was found in the two groups(P=0.361).

CONCLUSION:Lacrimal canaliculi rupture should be timely given surgical treatment. RS lacrimal tube can not only achieve good operation effect and reduce the probability of complications, but also has the advantages of simple surgical methods, good histocompatibility and no influence on the appearance of patients.
