Abstract :
Background: External DCR is the standard treatment for NLDO with previous history of chronic dacryocystitis. Our current
study presents series of patients with previous episodes of chronic dacryocystitis who underwent external
dacryocystorhinostomy (DCR) for nasolacrimal duct obstruction (NLDO) and compare their pre-operative characteristics,
post-operative outcome and surgical success rate. Methods: This hospital based prospective and interventional case
series of 60 patients with chronic dacryocystitis due to nasolacrimal duct obstruction (NLDO) who were treated by means of
external DCR was taken up for study. Surgery was done between June 2015 and December 2015 and the patients were
followed up for next 6 months. Results: During the study period 60 patients with NLDO underwent external DCR of whom
38 (63.33%) were females and 22 (36.66%) were males. Mean age was 44. 93 ± 15 years. Chronic dacryocystitis due to
NLDO was found in 50 patients (84%) while rest 10 (16%) had other reasons. An overall success rate of external DCR was
88.6% in patients with chronic dacryocystitis. Mean post operative follow up time was 180 days. Conclusion: No significant
difference in the success rate of External DCR in patients with or without previous history of dacryocystitis.
