Infant’s eyes are teary for the following reasons: 1, because the nasal bridge of the infant is not developed, resulting in lid inversion of the eyelash stimulation leads to tears, this situation does not require special treatment, if the tears are serious, lightly pull the nasal bridge eyelid skin, fixed with tape, so that the eyelashes do not touch the eyeball can be. In this case, parents should massage the lacrimal sac area on the nasal bridge side of the affected eye in order from top to bottom, using the thumb to press against the skin and apply gentle pressure to the lacrimal sac area 2 to 4 times a day. If the massage does not work, you can go to the hospital for tear duct flushing. 3, if the tearing is accompanied by discharge, it may be congenital dacryocystitis. It can occur anywhere between the junction of the lacrimal sac and the nasolacrimal duct to the lower mouth of the nasolacrimal duct. Because the tear ducts are not developed to normal, the tears cannot drain properly, so that the tears and bacteria are full in the tear sac, causing secondary infection. This condition requires repeated tear duct irrigation, and if that does not work, lacrimal duct exploration is required. Therefore, there are various causes of lacrimation in infants, and appropriate treatment should be given after the cause is identified.
