Abstract

Purpose

To evaluate the long term effectiveness of double silicone tube intubation in the treatment of acquired nasolacrimal duct (NLD) obstruction.

Methods

The authors treated 68 eyes of 40 patients with acquired NLD obstruction. The resolution of preoperative symptoms and signs of NLD obstruction was evaluated 18 months after the operation.

Results

The mean age of patients was 64.7 years and the mean follow-up period was 24.91 months. The symptoms and signs of NLD obstruction were improved in 85.29% of the patients. The partially obstructed group showed a higher success rate (89.29%) than the completely obstructed group (50.0%). A prolapse of silicone tubes to the ocular side was observed in 2 eyes, and 2 eyes had inflammatory signs after the procedure.

Conclusions

Double silicone tube intubation is an effective primary therapy with NLD obstruction, especially for patiensts with simple partially obstructed NLD instead of dacryocystorhinostomy.
