Congenital nasolacrimal duct obstruction (CNLDO) often resolves by age 1, or otherwise requires surgical intervention. This study evaluates the procedure types and outcomes of children undergoing NLDO intervention at our institution.
A retrospective review of patients, age 0-18, seen at our institution between June 2007 and December 2015, and treated for NLDO were included. Patients previously treated at outside hospitals were excluded.
A total of 1008 patients (494 females, 1660 eyes) were included. 74% were Caucasian. 64.4% of patients had bilateral treatment. The mean age at initial surgery was 1.7 ± 1.8 years. The most common initial procedure was probing and irrigation (P&I) (78.2%), followed by balloon dacryoplasty (BD) (19.8%), and tube or stent placement (1.9%). The mean age at initial procedure was 1.4, 2.5 and 5.0 years, for the P&I, BD and stent groups respectively. For patients requiring more procedures, the first procedure mean age was 1.8 years. 90.3% of total eyes did not require a second procedure. 91.3% of eyes that underwent P&I as the initial procedure did not require a second procedure, compared with 88% and 75.8%, for BD and stenting respectively. Sub-analysis including prematurity, Downs syndrome, craniosynostosis or dacryocystocele will be presented in the poster.
P&I was the most common initial intervention, with success rates similar to existing studies. Of those patients who required >1 procedure, the initial age of treatment was 1.8+ years. Delayed initial treatment resulted in lower success rates.
