The Incidence of Pediatric Dacryocystitis among a Population-Based Cohort of Infants with Congenital Nasolacrimal Duct Obstruction
Journal of AAPOS(2024)
摘要
PurposeTo report the incidence, clinical characteristics, and outcomes of acute dacryocystitis among a large, population-based cohort of children born with congenital nasolacrimal duct obstruction (CNLDO) over a 10-year period.MethodsThis multicenter retrospective, population-based cohort study included all patients diagnosed with acute dacryocystitis in a cohort of patients diagnosed with CNLDO before age 5 years in Olmsted County, Minnesota, United States of America from January 1, 1995, through December 31, 2004.ResultsOf 1,998 patients with CNLDO, there were 70 cases (36 female [(51%)]) of acute dacryocystitis during the study, yielding an incidence rate of 243 per 100,000 children (95% CI, 170-316). Mean age at diagnosis was 9.0 months. Patients who developed dacryocystitis were significantly less likely to be born via C-section (OR = 0.29, P = 0.009). Less than half of patients with dacryocystitis were treated with oral/intravenous antibiotics (46%), but whose who were had a significantly higher odds of requiring probing (OR = 8.50, P = 0.004). Spontaneous CNLDO resolution was significantly less likely to occur in patients diagnosed with acute dacryocystitis compared with those without (OR = 2.46, P = 0.001). The median age of spontaneous resolution in the dacryocystitis group (6.0 months) was significantly older than the uncomplicated CNLDO group (P = 0.012).ConclusionsPediatric acute dacryocystitis is an uncommon complication of CNLDO and is associated with both a lower likelihood of and older age at spontaneous resolution of CNLDO symptoms.
