Hi. I'm Dr. Rick and I have two decades of ophthalmology experience. I'm online and happy to answer your question today.
It sounds like your daughter is suffering from nasolacrimal duct obstruction (NLO).
The good news? 95% of the time this resolves on its own by the time a child is 1 year old.
Here is some information on this condition:Epiphora
is diagnosed when the baby has a watery eye all the time that is not associated with crying. Nasal lacrimal duct obstruction (NLO) is the most common cause of infantile epiphora and occurs in about 5% of babies. In NLO the tear duct does not open at birth, usually due to a small flap (valve) of tissue blocking the end with the remainder of the lacrimal system being normal. On rare occasions a secondary bacterial infection (dacryocystitis) can set in causing a yellowish, purulent discharge. Antibiotics, along with gentle massage, would be indicated in such a case.
Non-infected NLO is treated with lacrimal sac massage using the parent’s index finger to gently push on the corner of the eyelids toward the nose with the hope of causing enough hydrostatic pressure to snap open the obstruction. The majority of cases either resolve spontaneously or with this simple technique.
If dacryocyctitis is present, or if the NLO has not resolved with the above treatment by about 4 months of age an evaluation by an ophthalmologist
is indicated. In the office the ophthalmologist can do a nasolacrimal duct probing which resolves the issue in over 97% of cases. If this does not work a silicone tube can be threaded through the lacrimal system. This tube is then left in place for approximately 6 months and resolves the NLO in approximately 99% of cases. This procedure is usually done in the operating room under general anesthesia.
