Abstract

Purpose

To evaluate the effects of silicone tube intubation in patients showing common canalicular obstruction in dacryocystography.

Methods

We conducted a retrospective chart review of 136 eyes of 93 patients who underwent silicone tube intubation and who were followed for more than 6 months. The patients were divided into 2 groups: the normal canaliculus group (112 eyes of 72 pa-tients) and the common canalicular obstruction group (24 eyes of 21 patients). The demographic characteristics, degree of naso-lacrimal duct obstruction on probing, and functional and anatomical success rates of silicone tube intubation were compared be-tween the two groups. Surgery success was noted when the patient was satisfied with the ‘improved’ tearing symptom and the tear meniscus height decreased.

Results

On probing, 17 (70.8%) of 27 eyes revealed definite obstructive feeling at nasolacrimal duct in the common canalicular obstruction group, and there was no significant difference compared to the normal canaliculus group ( p = 0.639). The anatomical success rate of silicone tube intubation was 91.1% in the normal canaliculus group and 83.3% in the common canalicular ob-struction group, and the functional success rate was 85.7% in the normal canaliculus group and 75.0% in the common canal-icular obstruction group. There were no significant differences in success rates between the two groups ( p = 0.271, p = 0.161, re-spectively).

Conclusions

Silicone tube intubation can be considered as a primary treatment option for management of common canalicular obstruction.
