PurposeThe aim of this study was to describe high-resolution dacryoendoscopy findings for nasolacrimal duct obstruction (NLDO) in three representative pediatric cases with different etiologies.ObservationsIn a case of congenital NLDO, a mucosal membranous obstruction was observed at the distal end of the nasolacrimal duct (NLD), and a slit-shaped opening of the NLD was observed after perforation. In a case of acquired NLDO secondary to an adenoviral infection, a membranous obstruction was observed at the proximal NLD. In a case of NLDO with chronic dacryocystitis in a patient with Down syndrome, diffuse fibrous obstruction was observed.Conclusion and importanceHigh-resolution dacryoendoscopy enables a clearer visualization of pediatric lacrimal duct obstructions, leading to an improved understanding of their features.
