Outcomes of Early Lacrimal Probing Versus Lacrimal Sac Massage in Infants With Congenital Nasolacrimal Duct Obstruction

Lacrimal Duct Obstruction

This study aims to provide evidence on the optimal timing and efficacy of lacrimal probing in infants with congenital NLDO to minimize morbidity and healthcare costs .

Congenital nasolacrimal duct obstruction (CNLDO) manifests with symptoms such as excessive tearing, lash crusting, and mucopurulent secretions. A significant cohort study revealed that CNLDO affects one in nine newborns, highighting its public health significance 1. Controversies per-sist regarding the most appropriate time and type of intervention for managing CNLDO2 . Standard early management typically includes hydrostatic lacrimal sac massage combined with topical antibiotics. Many ophthalmologists believe that a majority of obstructions resolve spontaneously with massage; however, around 25% of children may require additional intervention such as probing 3. Currently, there is no established consensus on the optimal timing for intervention in theses cases. Because of the possibility of spontaneous resolution, some authors recommend postponing probing until after one year of age . Conversely, other studies suggest that delaying probing beyond six months may increase the risk of inflammation and fibrosis, potentially lowering the success rates of later interventions 4. Aim of the study This study aims to provide evidence on the optimal timing and efficacy of lacrimal probing in infants with congenital NLDO to minimize morbidity and healthcare costs .
