Newborns may cry due to an incomplete resorption of the embryonic membrane at the lower end of the nasolacrimal duct, causing tears and bacteria to accumulate in the lacrimal sac, which may sometimes lead to secondary infection. Tobramycin eye drops can be applied, along with massaging the inner corner of the eye for treatment assistance.
