Insights

Probing is a highly effective treatment for congenital nasolacrimal duct obstruction in children aged 12-84 months. This procedure remains a successful first-choice option even for older children and those with prior unsuccessful treatments.

Area of Science:

  • Ophthalmology
  • Pediatric Surgery

Background:

  • Congenital nasolacrimal duct obstruction (CNLDO) is a common condition in infants.
  • Early intervention is typically recommended, but the efficacy of probing in older children requires further investigation.

Purpose of the Study:

  • To evaluate the success rates of probing for CNLDO across different age groups.
  • To specifically assess the role and effectiveness of late probing in children over 24 and 48 months of age.

Main Methods:

  • Retrospective analysis of patient records from 2013-2017.
  • Inclusion of patients who underwent probing under general anesthesia for CNLDO.
  • Comparison of probing success rates across various age cohorts.

Main Results:

  • An overall success rate of 93.7% was observed in 143 eyes.
  • Success rates were high across age groups: 95.5% (12-18 months), 93.3% (18-24 months), 93.8% (24-48 months), and 86.6% (≥48 months).
  • For patients older than 48 months, the success rate after a second probing was 100%.

Conclusions:

  • Probing demonstrates high efficacy for CNLDO in children aged 12 to 84 months.
  • Probing is an effective first-line treatment for CNLDO in children over 48 months.
  • Probing can be successfully employed even in older children with a history of failed initial probing.
