Congenital Nasolacrimal Obstruction

Congenital nasolacrimal obstruction is a common disease that leads to tearing and mucoid discharge. Congenital nasolacrimal obstruction occurs in about 20% of children under one year of age. Most of these cases improve spontaneously, but sometimes the obstruction persists. Spontaneous improvement in the first year is high. Treatments include conservative therapy, probing and irrigation, inferior turbinate fracture, balloon dacryocystoplasty, endoscopic, or external dacryocystorhinostomy. The purpose of this article is to review the literature on the treatment of congenital nasolacrimal obstruction.
