The possible clinical causes of yellowish tears and excessive eye droppings in newborn babies include blocked nasolacrimal ducts, neonatal conjunctivitis, and neonatal dacryocystitis. 1. Nasolacrimal duct blockage: the nasolacrimal duct development of newborn babies is relatively immature, and the tears are not discharged smoothly, which makes the tears in a state of continuous secretion, and the eye droppings will be formed continuously. This situation requires parents to timely treatment of eye secretions. 2. Neonatal conjunctivitis: This condition is usually related to the conjunctiva being infected by pathogens such as bacteria, viruses and mycoplasma, etc. Inflammation of the conjunctiva causes the eye to reactively increase the secretion of tears, and the amount of eye droppings will increase accordingly. 3. Neonatal dacryocystitis: Lacrimal sac infection by pathogens is easy to appear nasolacrimal duct blockage, manifested as redness, swelling, accompanied by increased skin temperature, pressure and pain, as well as the secretion of purulent secretions, tears will also stimulate the increase in the secretion of and the formation of a greater number of eye droppings. Parents should pay attention to this condition and take their children to the hospital for treatment as soon as possible.
