Nasolacrimal duct obstruction (NLDO) is a common cause of persistent tearing and periocular discharge in infants. The presentation ranges from mild intermittent epiphora to significant, recurrent discharge, and symptom severity guides the initial management decision.
Management begins with an assessment of symptom severity. When symptoms are mild, observation alone may be warranted. When significant epiphora or discharge is present, a conservative, non-invasive first-line intervention directed at the lacrimal sac is the standard recommendation — with correct technique being a critical part of its effectiveness. In selected cases with notable discharge, an additional topical measure may be considered alongside this approach.
