A blocked tear duct (nasolacrimal duct obstruction) prevents tears from draining normally, leading to watery, irritated, or even infected eyes. In adults, this can result from inflammation, injury, or age-related narrowing. Massaging the duct (Crigler massage) can help open the blockage and promote drainage.
