Background: To ascertain the success of lacrimal intubation and DCR in alleviating epiphora due to functional nasolacrimal duct obstruction (FNLDO).
Methods: Consecutive adult patients with epiphora attending a tertiary lacrimal clinic from May 2010 to February 2021 were reviewed to identify cases with FNLDO. FNLDO was defined as epiphora with the exclusion of alternate causes of watering on clinical examination, patent lacrimal syringing, normal DCG, and post-sac delay on DSG. Epiphora resolution and improvement rates in FNLDO were compared between lacrimal intubation and endo-DCR.
Results: 23 endo-DCRs (20 patients, 65% females, mean age 68.9±12.2) and 41 intubations (29 patients, 61.2% females, mean age 65.0±14.1) performed in FNLDO were included. Resolution of epiphora was achieved in 15 of the DCR procedures (median follow-up 9 months) compared to 14 of intubations (median follow-up 10 months). Significant epiphora improvement (i.e., either improvement or resolution) was noted in 21 DCRs and 24 intubations. Seven patients undergoing intubation as the primary procedure had endo-DCR performed following the intubation. Among respondents to a phone questionnaire, 53.8% who had endo-DCR (median 69 months) and 50% that had intubation (median 28 months) reported significant improvement in epiphora.
Conclusions: Improvement in epiphora due to FNLDO was approximately 59% in intubations, while the success of endo-DCR was higher (91%). The long-term results of these interventions warrant further investigation.
