Abstract
Pediatric (congenital) nasolacrimal duct obstruction (PNLDO) is the most common cause of persistent epiphora in childhood. The incidence of PNLDO is 5–6% (ranging from 1.2 to 30%) of births. Spontaneous resolution is reported in 90% within the first year of life. Our treatments are geared to the 10% of patients that do not experience spontaneous resolution. This chapter discusses the typical presentation of the tearing patient as well as the differential diagnosis. The traditional therapeutic paradigm including primary probing, secondary probing with stent, choice of stent, and dacryocystorhinostomy is discussed with recent data to inform decision-making.
