Abstract Purpose: To report endoscopic findings of the lacrimal sac and nasolacrimal duct in infants with congenital nasolacrimal duct obstruction.

Cases and Method: This study was made on 8 sites of 7 cases with congenital nasolacrimal duct obstruction. The age ranged from 12 to 36 months. They were examined by lacrimal endoscopy under general anesthesia.

Findings: All sites of lacrimal sac and nasolacrimal duct were filled with white purulent mass. The inner wall of 6 lacrimal sacs and all nasolacrimal duct appeared uneven. Site of nasolacrimal duct obstruction resisted manual opening in all the cases but one.

Conclusion: The observed endoscopic findings show why congenital nasolacrimal duct obstruction fail to resolve spontaneously in infants after 12 months of age.
