Purpose:
To study the efficacy of dacryocystectomy (DCT) in reducing epiphora in cases of primary acquired nasolacrimal duct obstruction.
Methods:
This was a prospective, nonrandomized, interventional study conducted over a period of 12 months. All cases who either opted or satisfied our criteria for DCT in primary acquired nasolacrimal duct obstruction (age above 70 years) were included in the study. Patients with secondary nasolacrimal duct obstruction and those undergoing revision surgeries were excluded. Patients were asked to report the percentage improvement in postoperative watering subjectively. Munk score and fluorescein dye disappearance test (FDDT) were recorded pre- and postoperatively. Wilcoxon signed ranked test was used for analysis.
Results:
Eighty-two eyes of 65 patients were included. Most of the patients (46, 70.8%) were females. The mean age was 68.46 ± 5.7 years (range: 60-85 years). The mean subjective improvement in watering was 86.8%. The P value for preoperative and postoperative difference in Munk score and FDDT score was highly significant (P = 0.00001).
Conclusion:
Apart from providing relief from ocular discharge, DCT also provides significant improvement in watering. Patients can be preoperatively counseled regarding chances of reduction in epiphora following surgery.
