Background and Objectives: The purpose of this study was to evaluate the long-term outcome of primary endoscopic dacryocystorhinostomy (DCR) or conjunctivo-dacryocystorhinostomy (CDCR) in adults with nasolacrimal duct obstruction.
Subjects and Method : We retrospectively reviewed 31 eyes of 27 patients who underwent primary DCR or CDCR for anatomical or functional blockage of the lacrimal drainage system (4 males, 27 females, mean age 54.4±12.7 years). The mean follow-up period was 45.4±10.8 months. The main outcome measure for success was assessed by symptomatic improvement. Pre-operative CT findings and endoscopic findings, sites of obstruction, types of surgery, post-operative complications were evaluated and the outcome was assessed according to the level of obstruction and types of surgery.
Results: Two years after the surgery, the success rate was 83.9% including complete resolution of symptoms (64.5%) and partial improvement (19.4%). No improvement was reported in 16.1%. There was no significant difference in success rates of DCR according to the obstruction sites. Patients with functional blockage had worse success rate than those with anatomical obstruction.
Conclusion: Both endoscopic DCR and CDCR had successful outcome in the long term con-trol of epiphora and functional nasolacrimal duct obstruction showed worse prognosis when compared with anatomical obstruction.
