In medical language, obstruction of the tear duct is called nasolacrimal duct obstruction. This condition is indeed often experienced by newborn babies, whether in one or both eyes. So, what causes blocked tear ducts in infants and how to care?
Why can tear ducts in babies get blocked?
Normally, tears play an important role in supporting a person’s vision. This clear liquid will keep the eye moist, supply oxygen to the eye, remove substances that are at risk of irritating the eye, to coat the surface of the eye.
Tears produced by the tear glands, will be flowed into the tear ducts. Unfortunately, sometimes the tissue layer (membrane) in the tear duct actually closes so that it prevents the flow of tears about to enter.
As a result, the tear ducts are blocked in the baby, which then makes the tears remain welled on the surface of the eye. The most common reason why the tear ducts in the baby can get blocked, namely because the hole in the eyelid (punta) in the baby has not fully developed.
That is why, some tear ducts actually close so as to create a barrier for the entry of tears.
On the other hand, blocked tear ducts in infants can also be caused by:

How to treat a blocked tear duct baby?

Most cases of tear duct obstruction in infants will usually heal on their own without special treatment. This depends on the severity of the tear block experienced by your child.
Your doctor may advise you to regularly massage your baby’s tear bags slowly, to help smooth the blockage. If the baby is less than 1 year old and has an infection in the tear ducts, antibiotic eye drops and ointments may be an option.
Treatment that does not work with conservative methods, can be continued with invasive methods. In this case, the doctor will perform surgery by inserting a medical instrument ( probe ) into the tear duct.
The goal is of course to launch a blockage that blocks the flow of tears. Not only that, doctors can recommend stenting to keep the channel open. Or by using a balloon catheter to widen the baby’s tear ducts.
