Many new mothers find that one of their baby’s eyes is very teary and has a lot of eye boogers, sometimes even the eyes are burnt, what is going on? Is it a fire? –This is not a fire, but a blocked nasolacrimal duct. What is the problem of nasolacrimal duct obstruction? Nasolacrimal duct obstruction is more common in newborns and young infants. This is caused by the lower nasolacrimal duct being closed at the nasal opening by congenital membranous tissue, which does not break about 4 weeks after birth; or by the duct being underdeveloped and forming folds, flaps or mucosal diverticula, causing tears and secretions from the tear duct to be trapped in the tear sac and causing dacryocystitis. What should new parents do? If the baby’s eye discharge is sticky, you can use warm and wet towels to remove the eye discharge after hot compress; use eye drops or saline drops suitable for babies under the guidance of a doctor. Before dropping eye drops, use your thumb or index finger to press the root of your baby’s nose and the central part of the inner canthus of the eye and squeeze it in the direction of the eye to press out the pus, wipe it off and then drop the eye drops, the effect will be better. Giving your baby a proper massage can help the nasolacrimal ducts to flow smoothly. Most babies with blocked nasolacrimal ducts will disappear around 6 months, while some babies may disappear a little later. There are only a few more serious cases that require a hospital visit for tear duct flushing or surgery.
