About

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

Full description

Congenital nasolacrimal duct obstruction is a common condition during the first few years of childhood. Most cases may resolve spontaneously, but the remaining children whose blockage does not resolve may require primary probing. Controversy remains regarding the optimal timing of the probing procedure. Another controversy is related to the setting of surgery. Therefore, we try to investigate the factors that affected the outcome of treatment of congenital nasolacrimal duct obstruction under the same surgical doctor during the past 13 years in our hospital.

Trial design

800 participants in 1 patient group

Probing, topical anesthesia

Description:

Nasolacrimal duct obstruction (NLDO) is a quite common condition among the infants. An imperforate membrane at the distal end of the nasolacrimal duct is the main cause of occlusion. Children with the signs of NLDO presenting with epiphora and/or mucous discharge were included in this study. Intervention with probing under topical anesthesia was performed on the same surgeon. And success rate was evaluated.

Treatment:

Procedure: Probing
