Causes of newborns with yellow watery eyes, mainly including acute conjunctivitis, nasolacrimal duct, as follows: 1, acute conjunctivitis: if the newborn is infected with Chlamydia trachomatis, or infected with bacteria and other pathogens, will lead to eye infections, causing newborns with yellowish watery eyes, and conjunctival congestion is very obvious. In this case, you can apply tobramycin eye drops, or erythromycin ointment and other treatment for newborns; 2, nasolacrimal duct: normal newborn tears will flow into the nasal cavity, which belongs to the nasal cavity of the normal circulation pathway. After a newborn’s nasolacrimal duct is blocked, the tears in the eye socket can’t effectively flow into the nasal cavity, which will lead to blockage of tears and cause infection, resulting in yellowish water in the eyes and watery eyes and other symptoms.
