Most newborns’ eyes begin to produce tears at about 3 weeks, and these tears flow through the tear ducts in the inner corners of the eyes to the nose. During the first month or two of life, one or both eyes will have a yellow, sticky discharge, usually due to a blockage of the tear duct. There is a membrane in the baby’s nasolacrimal duct that is supposed to degenerate with birth so that tears can flow, but some children do not have this membrane completely open, and the tear ducts become blocked, at which point tears accumulate in the eyes. The tears that are not drained in time are prone to infection, and the fluid coming out of the baby’s eyes is yellow, indicating that the blocked tear duct is infected. Treatment: (1) Drugs: You can apply eye drops for children and avoid applying drugs such as ofloxacin, which is used by adults. Before giving the baby eye drops, the bottle of eye drops must also be some distance away from the baby’s eyes, not too close, in case the baby appears to avoid, resist or other actions, resulting in the mouth of the bottle touching the baby’s eyes. Note that the action must be gentle and quick, after dropping to gently wipe away the outflow with cotton, to keep the baby’s face dry and clean. (2) Parents can wash their hands and then put them on the affected child’s tear ducts and rub them gently. Be careful not to wipe the affected eye with a towel and then wipe the other eye, as this may lead to cross-infection and the other eye will soon behave in a similar manner. If, after the above treatment, the child’s condition does not improve significantly, the child’s eye discharge becomes heavier and heavier, or is accompanied by significant redness and swelling in the eyelid area, a visit to the ophthalmologist is required.
