Tearing occurs in the tear duct system. This system allows tears to drain from the eyes into the nose and usually opens in the first few months of life. In some infants, however, the system remains blocked, resulting in the eyes overflowing with tears and collecting mucus.
Tearing may result from other ocular conditions, the most serious of which is Glaucoma. Gentle massage of the tear duct can occasionally assist in relieving the blockage. If massage and observation are unsuccessful, a tear duct probe or more involved surgery is occasionally required.
