Problems of the lacrimal system in children.
The lacrimal system is composed of various glands to produce tears and a drainage system for tear removal. The most common abnormality is a defect or blockage in the drainage system, a blocked nasolacrimal duct. Most of the evidence favors conservative management of this condition, reserving probing for those that fail to resolve by one year of age.
