Diagnostic method of lacrimal occlusion in neonates
Normally, tears are produced by the lacrimal gland, keeping the eyes lubricated and clean. After tears are produced, the movement of the eyes forces the tears into ducts in the inner corners, which drain the tears from the eyes into the lacrimal duct and into the back of the nose. If this duct is completely or partially blocked, the tears that cannot drain out will block the lacrimal duct.
