The aim of this study is to compare results of endoscopy assisted nasolacrimal probing with the standard simple probing in cases with congenital nasolacrimal duct obstruction . Furthermore, investigators will identify associated anatomical anomalies. Investigators believe results of this study can be valuable in better understanding of this disease and provide a high evidence level necessary to propose a classification and management algorithm. Children with symptoms of unilateral or bilateral congenital nasolacrimal duct obstruction, no past surgical management, with one or more of the below criteria will be included:

The patency of the system will be tested by irrigation with 1 ml normal saline. A cannula was introduced via the upper or lower canaliculus as far as the lacrimal sac and fluid injected through the system from a 5 ml syringe. Nasal endoscopy and irrigation will be performed simultaneously and free flow of fluid from the lacrimal sac to the nose will confirm anatomical patency of the system
