Successful Congenital Nasolacrimal Duct Obstruction Probing In A 11 Years Old Boy With 1 Year Follow Up: A Case Report

One common cause of epiphora in babies is congenital nasolacrimal duct obstruction (CNLDO). 5% to 20% of people have it, however only 2% to 6% will require treatment. An 11-year-old boy complained of having an excreted and watery eye since birth when he arrived at the hospital. The outcome of the dye disappearance test is +4. It was decided to do probing operations on the patient. After probing, there was positive fluorescein flow in the nasolacrimal duct. A dye disappearance test was conducted one week following the probing procedure, and the results are negative. Patients no longer report having sticky and watery eyes. The CNLDO's management is still debatable. For children less than 36 months, probing can be the main course of treatment with a success rate of 78–93%. The success rate is even lower for older kids. The best moment to go more into the CNLDO is still up for discussion. The high rate of patient success with probing over the age of two indicates that probing may be tried before a more elaborate intervention is considered.
