Abstract
Objective To investigate the treatments for chronic dacryocystitis by lacrimal punctum with the fifth generation lacrimal endoscope, and to evaluate the effect and security between the two different methods in clinical applications. Methods Clinical case-control study of 128 patients (128 eyes) with chronic dacryocystitis were collected from August 2013 to December 2014 in Ophthalmic Center of Foshan Hospital Affiliated to Southern Medical University, the patients were randomly divided into two groups by random number table. Group A (66 patients 66 eyes) underwent the fifth generation lacrimal endoscopic microdrill with full intubation while group B (62 patients 62 eyes) underwent the fifth generation lacrimal endoscopic laser with full intubation. Effective rate, operative time of lacrimal endoscope and complications were statistically analyzed between the two groups. Results All nasolacrimal duct obstructions (128 eyes) eliminated after the operation 100% (128/128). The effective rate of group A was 90.91% (60/66), and group B was 82.26% (51/62), there was no statistically significant difference between the two groups (P >0.05). The operative time of lacrimal endoscope was 16.2 4.18min in group A and 27.3 5.32min in group B, there was statistically significant difference between the two groups (P 0.05). There were no serious intraoperative and postoperative complications in two groups. Conclusions The fifth generation lacrimal endoscope can treat chronic dacryocystitis under microdrill or laser by lacrimal punctum, it is not only safe, effective, but also more flexible than traditional one-piece lacrimal endoscope during the operation. This is a kind of visual and micro-invasive surgery for treating chronic dacryocystitis, and worthy of clinical application. Key words: Lacrimal endoscope; Chronic cryocystitis; Microdrill; Laser; Full lacrimal intubation
