Abstract
Aims: To evaluate the outcome of nonendoscopic endonasal dacryocystorhinostomy (NEN‑DCR) in patients
with nasolacrimal duct obstruction (NLDO) in India. Methods: Retrospective case series of NEN‑DCR
between July 2012 and October 2014. All patients had follow‑up >3 months. Success was defined anatomically
as patency on irrigation and functionally as relief from epiphora. Statistical Analysis Used: Fischer’s exact
test and Chi‑square test. Results: A total of 122 patients (134 eyes; 81 female; mean age 37 ± 18 years)
were included. Indications were primary acquired NLDO in 92 (68%) eyes of adults (>18 years), NLDO
in children (<18 years) in 22 eyes (16%), acute dacryocystitis in 13 eyes, failed prior DCR in six eyes, and
secondary acquired NLDO in one eye. Mean duration of surgery was 36 min (range: 16–92). At a median
follow‑up of 6 months (range: 3–15), 86% eyes had functional success and 85% had anatomical success.
Revision NEN‑DCR was successful in 13/16 eyes. All patients with acute dacryocystitis were completely
symptom‑free at final visit. In children, (17/22) 77% achieved functional success after primary NEN‑DCR
which improved to 100% after one revision. Tube‑related epiphora and granuloma in ten eyes resolved after
removal. Conclusion: NEN‑DCR gives good outcome in primary NLDO and is also effective in those with
acute dacryocystitis and in children with NLDO. The technique obviates the need for an endoscope and has
an acceptable safety profile and thus may be particularly suited for the developing nations.
