title: Congenital nasolacrimal atresia in 4 alpacas.
abstract: Four alpacas, 2 wk to 1 y of age, were diagnosed with congenital atresia of the nasal puncta of the nasolacrimal duct. Dacryocystorhinography confirmed and localized the atresia. All animals were treated successfully by surgical creation of nasal puncta and patency was ensured by placement of a surgical stent for several weeks.
