title: The management of pediatric lacrimal problems.
abstract: The most common cause of tearing in the pediatric age group is blockage of the distal end of the nasolacrimal duct at the valve of Hasner. Evaluation with fluorescein using the dye disappearance test and the primary dye test, although not always as accurate as in adults, is possible. Conservative treatment is attempted initially followed by probing and, if necessary, silicone intubation. Less common causes of tearing are punctal atresia and congenital lacrimal sac fistula, which are usually diagnosed later, requiring opening of the atretic membrane and excision of the fistula tract, respectively. Amniotoceles are usually seen within a week of birth and are treated aggressively with medication and/or probing to prevent acute dacryocystitis.
