Infants with tearing eyes and yellow eye droppings may be associated with bacterial conjunctivitis, incomplete development of the tear ducts, and obstruction of the nasolacrimal ducts. 1. Bacterial conjunctivitis: it is an acute purulent conjunctivitis caused by gonococcus and meningococcus, etc. There will be yellowish-white discharge from the eyes and tearing. 2. Incomplete development of the tear ducts: Incomplete development of the tear ducts can cause poor tear drainage, which leads to tearing of the eyes. If there is an infection, it will cause dacryocystitis, which will lead to the appearance of yellow eye droppings. 3. Nasolacrimal duct obstruction: when the nasolacrimal duct is obstructed, the tear fluid accumulates in the tear duct, which can easily induce eye infections, resulting in tearing eyes and yellow eye droppings. It is recommended that babies with tearing eyes and yellow eye droppings go to the hospital in a timely manner, after clarifying the cause of the disease, under the guidance of the doctor for standardized treatment.
