Objective: to evaluate the efficacy of conservative and medical management of pediatric congenital nasolacrimal duct obstruction (CNLDO) associated with nasal allergy.



Method: The current research is a prospective study on 28 pediatric cases (40 eyes) visiting ENT and ophthalmology departments of Minia university hospital presented with epiphora due to CNLDO above age of 1 year and below the age of 8 years. The epiphora is associated with nasal allergy. Those cases had been received medical and conservative treatment for 3 months.



Results: All 28 cases received conservative measures and medical treatment prescribed by ophthalmology and E.N.T doctors. These measures were successful in cure of epiphora in 11 of 28 patients (16 of 40 eyes). The overall success rate is 39.3% of our patients (40% of eyes).



Conclusion:

We showed for the first time the impact of E.N.T evaluation and nasal allergy conservative management on the outcome of CNLDO from total number of 28 patients up to 40% showed improvement with medical treatment. So, many pediatric cases will not need invasive or surgical intervention. Lead to minimizing childhood morbidity as regarding hazards of general anesthesia and or surgical complications.
