What’s wrong with one of the baby’s eyes that keeps tearing up?

Babies with tears in one eye may be associated with inverted eyelashes, or may be caused by congenital nasolacrimal duct obstruction, conjunctivitis, and so on.
1. Inverted eyelashes: If a baby has inverted eyelashes in one eye, the growth of eyelashes in the direction of the eyeballs will form an irritation to the eyeballs, leading to an increase in the secretion of tears, resulting in the inability of tears to be discharged in a timely manner, which will lead to the symptom of constant watering of the eyes, which can be accompanied by a sense of foreign body in the eyes, itchy eyes, and other symptoms.
2. Congenital nasolacrimal duct obstruction: due to congenital nasolacrimal duct obstruction in one of the baby’s eyes, the tears in that side of the eye can’t be discharged through the nasolacrimal duct, resulting in excessive accumulation of tears, which will cause the symptom of constant watering of the eyes, and may be accompanied by pus secretion, pain and other symptoms.
3. Conjunctivitis: babies do not pay attention to eye hygiene, often with dirty hands rubbing the eyes, easy to cause eye infections, induced conjunctivitis, under the stimulating effect of inflammation, will cause the symptoms of constant tearing of the eyes, can be accompanied by photophobia, foreign body sensation and other symptoms.
