Infants with tears in the corners of the eyes may be due to the following two reasons: 1, tear duct obstruction: also known as congenital dacryocystitis, congenital dacryocystitis leads to tear duct obstruction mainly due to a layer of membrane at the lower end of the nasolacrimal duct, which is not broken before development, causing tears after birth can not pass through the tear duct, smoothly excreted into the nasal cavity and absorbed, resulting in the phenomenon of infants with tears. If the nasolacrimal duct is obstructed and the diagnosis is clear that it is neonatal lacrimal sacculitis, it needs to be treated accordingly. Early on, eye massage can be performed, mainly in the lacrimal duct area towards the nasal cavity. If there is still runny eyes and more purulent discharge from the corners of the eyes, it is recommended to go to the ophthalmology department for lacrimal flushing and lacrimal duct exploration, which is generally better for infants within six months. 2. Inverted eyelashes: Some infants are fat and form lid entropion and inverted eyelashes after birth, and also have a low and flat nasal bridge, which makes them more prone to lid entropion and inverted eyelashes, and if the runny eyes are caused by lid entropion and inverted eyelashes, you can If it is caused by entropion or impingement, you can leave it alone for the time being and just follow up and observe.
