Symptoms of blocked tear ducts
Your child will have wet eyelashes or extra tears. Since the tears cannot drain out of the tear duct, they spill over the lashes, often onto the cheeks.
Your child’s eyelids may stick together with mucus, especially in the morning. Mucus is a sticky liquid that is normally dissolved in the tears. When tears do not flow well, however, the mucus stays on the outside of the eye. This mucus is normal. It is not the same as pus (a yellowish or greenish liquid), which is a sign of an infection.
Your child may often have a red eye. This is caused by infections, which are more common when tears do not drain properly.
Extra tears do not always mean the tear ducts are blocked
Extra tears are not always caused by blocked tear ducts. If your child has extra tears, an eye doctor should check your child’s eye(s).
