Abstract
Purpose :
To evaluate the effect of lacrimal endoscopy on operation time of silicone tube intubation in patients with acquired nasolacrimal duct obstruction.
Methods :
We conducted a retrograde chart review of 168 eyes of 107 patients who were diagnosed with acquired nasolacrimal duct obstruction and underwent silicone tube intubation from January 2019 to February 2023. The effect of lacrimal endoscope on success rate of sugery and operation time was analysed.
Results :
Of 168 eyes, 58 eyes underwent silicone tube intubation with lacrimal endoscope, and 110 eyes underwent silicone tube intubation without lacrimal endoscope. The success rate in the group with lacrimal endoscope was 93.10%, and the success rate in the group without lacrimal endoscope was 86.36%. The success rate of the surgery in the group with lacrimal endoscope was relatively higher than that in the group without lacrimal endoscope, but there was no statistically significant difference (p=0.213). The average operation time in the group with lacrimal endoscope was 10.98 ± 2.24 minutes, and the operation time in the group without lacrimal endoscope was 12.44 ± 4.08 minutes. The operation time in the group with lacrimal endoscope was relatively shorter and statistically significant (p=0.003). When analyzing correlation between success rate and operation time, the success rate decreased by 0.877 times when the operation time increased in the entire group, and there was statistical significance (p=0.022). There was no statistical significance in the correlation between operation time and success rate in the group with lacrimal endoscope. And in the group without lacrimal endoscope, the success rate decreased by 0.865 times when the operation time increased, and there was statistical significance (p=0.019).
Conclusions :
Lacrimal endoscopy is considered an effective treatment that can shorten the operation time while accurately diagnosing the cause and extent of obstruction by investigating the inside the nasolacrimal duct.
