A Survey of Pediatric Ophthalmologists to Assess Practice Patterns for Primary Surgical Management of Nasolacrimal Duct Obstruction.

Abstract

Purpose: To survey current practice patterns of pediatric ophthalmologists regarding primary surgical management of infantile dacryostenosis.

Methods: Responses to a five-question survey were cross-tabulated to compare surgery preferences across patient age ranges and intubation method. Surveys were submitted to members of the American Association for Pediatric Ophthalmology and Strabismus following institutional review board approval.

Results: Results from 142 completed surveys were analyzed. A bimodal distribution of reported propensity to intubate the nasolacrimal duct during primary surgery for dacryostenosis was observed, with one group of ophthalmologists intubating frequently and a second group intubating rarely. For patients younger than 24 months, 33 of 142 surgeons (23%) preferred to intubate 91% or more of the time and 76 of 142 (54%) preferred to intubate 10% or less of the time. For patients older than 24 months, the overall preference for intubation increased compared to the younger patient age group (P < .0007). In older patients, 52 of 142 surgeons (37%) preferred to intubate 91% or more of the time and 45 of 142 surgeons (32%) preferred to intubate 10% or less of the time. The most common preferred intubation methods were self-threading monocanalicular stent (42%) and metal-swaged bicanalicular stent (21%). Surgeons who preferred self-threading monocanalicular stents more often also preferred intubation procedures.

Conclusions: Best practice for infantile dacryostenosis remains a surgeon preference, with some surgeons performing intubation frequently and others performing it rarely. Overall estimated intubation rates for primary surgery increased from 36% in children younger than 24 months to 50% at age 24 months or older. [J Pediatr Ophthalmol Strabismus. 2022;59(1):35-40.].
