Neonatal dacryocystitis

Neonatal dacryocystitis is due to the absence of degradation of the embryonic residual membrane at the lower end of the nasolacrimal duct, which obstructs the lower end of the nasolacrimal duct, causing tear fluid and bacteria to remain in the lacrimal sac, causing secondary infections. Neonatal dacryocystitis is a very common congenital eye disease in infants and young children. It is also a common and frequent disease in pediatric ophthalmology. The baby's eyes are often teary. There are many concentrated secretions flowing out of the baby's eyes, and the onset time can be earlier or later, some have symptoms on the first day after birth, and some can appear after one week or one month later.
