Summary

The purpose of this study was to investigate various potential factors that affected the outcome of treatment of congenital nasolacrimal duct obstruction.

Conditions

  • Congenital Nasolacrimal Duct Obstruction

Interventions

PROCEDURE

Probing

A punctal dilator was used for dilating the punctum. The nasolacrimal system was irrigated through either the lower or upper punctum with a hollow 23-gauge irrigating cannula attached to a syringe. A #0 (or #00) Bowman probe was passed through either the lower or upper canaliculus into the lacrimal sac and then directed downward through the nasolacrimal duct into nasal cavity. A "Hard" resistance could be felt as the probe touched the end of the nasolacrimal duct. A "Pop" tactile sensation might be noted while the probe passing through an obstruction at the valve of Hasner.
