Conventional or endoscopic probing for congenital nasolacrimal duct obstruction
1Department of Ophthalmology, Medical Faculty, Hacettepe University, Ankara, Turkey.
Insights
Conventional probing is effective for infant congenital nasolacrimal duct obstruction. Endoscopic probing offers a slight advantage in reducing the need for repeat procedures in challenging cases.
Area of Science:
- Ophthalmology
- Pediatric Surgery
Background:
- Congenital nasolacrimal duct obstruction (CNLDO) is a common condition in infants.
- Conventional probing is a standard treatment, but success rates can vary.
Purpose of the Study:
- To compare the efficacy of conventional probing versus endoscopic probing for CNLDO in infants.
- To evaluate the need for repeat procedures in both treatment groups.
Main Methods:
- Conventional probing was performed on 22 eyes of 18 infants (7-14 months).
- Endoscopic probing with intranasal visualization was performed on 18 eyes of 14 infants (7-13 months).
- Both groups underwent primary probing for CNLDO.
Main Results:
- Conventional probing required re-probing in 2 out of 22 cases (9.1%).
- Endoscopic probing required re-probing in 1 out of 18 cases (5.6%).
Conclusions:
- Conventional probing is generally effective for infant CNLDO.
- Endoscopic guidance may be beneficial in cases that fail initial conventional probing, offering direct visualization of the inferior meatus.
Purpose:
To compare conventional and endoscopic probing for congenital nasolacrimal duct obstruction in infants.
Methods:
Conventional probing was performed in 22 eyes of 18 patients, age range 7-14 months (mean 11.4 months). Probing was done with intranasal endoscopic visualization in 18 eyes of 14 patients, age range 7-13 months (mean 11.2 months). All were primary probing cases.
Results:
After conventional probing 2 of the 22 cases required reprobing. After endoscopic probing only 1 of the 18 cases required reprobing.
Conclusions:
In most cases of congenital nasolacrimal duct obstruction endoscopy is not required; however, in failed cases direct visualization of the inferior meatus with endoscopic guidance may be helpful.
