This problem happens in some babies when the tear duct does not form as it should. A thin membrane may cover the opening of the duct into the nose.
Things that may raise the risk of this problem are:
Having a face or skull that does not form as it should
Problems may be:
Eye redness, warmth, and swelling
Mucous discharge from the eye
Crusting on the eyelid
The doctor will ask about your baby’s symptoms and health history. An eye exam will be done. Your baby may need to see an eye specialist.
The tear duct will be checked for blockages. This can be done with a dye disappearance test. This can confirm the diagnosis.
This problem often goes away in the first year of life. If it does not, the goal of treatment is to open the tear duct. They may be done with:
Massage—The doctor may gently push on the area where the tear duct runs out of the eye, between the baby’s eye and nose. This helps to push tears through the duct and open the membrane. This will also need to be done at home until the tear duct has opened.
Probing—A tiny probe may be placed into the duct to open it. It may also be dilated with a balloon or stented to keep it open.
Surgery—Babies who are not helped by these methods may need surgery. A tiny, flexible instrument will be placed into the tear duct. The doctor may then flush fluid through it. A laser may be used to cut away any blockage.
There are no known methods to prevent this health problem.
