Congenital nasolacrimal duct obstruction outcomes.

Objective: To characterize children with congenital nasolacrimal duct obstruction (NLDO) seen by a pediatric ophthalmologist in terms of initiation of tear duct massage and need for lacrimal duct probing. Design: Retrospective chart review. Participants: All children with a diagnosis of congenital NLDO managed by one pediatric ophthalmologist (SH) at a tertiary pediatric center (McMaster Children's Hospital, Hamilton, Ontario, Canada). Methods: Charts were reviewed to determine the percentage of patients requiring nasolacrimal duct probing. Secondary outcomes were percentage of patients who had tear duct massage, accurate or inaccurate, initiated by the referring provider. Results: Overall, 113 patients with a mean age of 1.8 ± 1.5 years at presentation were included, and 55 (48.7%) were male. Most patients (83.2%) were referred by a primary care provider (family physician or pediatrician) and the remainder by optometrists (13.3%) or ophthalmologists (3.5%). Accurate tear duct massage was initiated by referring providers in 23% of cases. Ultimately, 44.2% of cases required probing, and 4.4% were still pending follow-up at time of data collection. Of children who learned accurate massage technique, 56% avoided surgical intervention, even when proper massage is introduced after 12 months of age. Conclusion: Most patients referred to pediatric ophthalmology for congenital NLDO did not have an appropriate trial of tear duct massage before referral, and less than half of patients required probing after appropriate massage was initiated. Educating primary care providers and optometrists on proper initiation of tear duct massage may reduce the volume of congenital NLDO referrals to pediatric ophthalmology, a subspecialty with limited physicians and long wait times.
