This is due to nasolacrimal duct gambling blockage. Small infants can cause excessive tear production in one or both eyes, these tears flow down the cheeks and do not flow into the nasal cavity through the nasolacrimal duct. For newborns the blocked nasolacrimal duct is due to the entrance above being covered by mucous membranes that are left behind because they did not disappear in time at birth, usually by the time the child is 9 months old the nasolacrimal duct can open on its own without treatment. Alternatively you can speed up the opening of the nasolacrimal duct by gently massaging the area on either side of the nasal bridge below the inner corner of the child’s eye. However, this massage should always be done under the guidance of a pediatrician. As the nasolacrimal duct is blocked and there is a purulent discharge from the eye, this is not a true eye infection, so antibiotics are not needed. This phenomenon will naturally disappear as the nasolacrimal ducts develop. In rare cases an ophthalmologist will need to consider surgery to open the blocked nasolacrimal duct.
