Blocked Tear Duct (Nasolacrimal Duct Obstruction)

Gentle, Expert Care for Your Baby’s Eyes


Young boy with a blocked tear duct (nasolacrimal duct obstruction) visits a Nemours eye specialist for expert care.

The body’s lacrimal (tear duct) system is made up of glands and ducts that work with our eyelids and lashes to keep our eyes from drying out. When tear ducts are too narrow or blocked, tears can’t drain the way they should. That makes the eyes water a lot, swell or even become infected. Since many babies are born with a tear duct system that isn’t fully developed, a blocked tear duct tends to happen most often in infants.

If your child has a blocked tear duct (also called “congenital nasolacrimal duct obstruction”), we can show you how to take care of the affected eye and prevent infection. If it doesn’t get better on its own, our pediatric eye experts at Nemours can treat this very common condition in kids.

Blocked Tear Duct Services We Offer

Blocked Tear Duct Services We Offer


For a blocked tear duct, we start with the simplest options. Your child’s care may include massage (using gentle motions around the eye to help open the duct) or giving topical antibiotic eye drops (medication to treat infection).

If your child needs surgery, it may involve:

  • probing — gently inserting a thin surgical probe to open a blocked duct 
  • balloon dilation — inserting a thin tube with a tiny balloon to widen the tear duct
  • intubation — threading a tiny tube through the tear ducts to the inside of the nose to help babies with severe blockage

Whatever kind of treatment your child needs, our expert eye care team knows how to help kids feel relaxed and comfortable during treatments. A Child Life specialist can even use play and distraction to make exams and treatment less scary for babies and young children.
