Dacryostenosis; Blocked nasolacrimal duct
Treatment For children with incomplete nasolacrimal duct development, massaging the lacrimal sac area several times a day, as instructed by an ophthalmologist, may be enough to open the tear duct. Persistent cases may require opening by a probing procedure. This may occasionally require anesthesia. Prognosis Congenital tear duct blockage often clears spontaneously by 6 months of age. If it does not clear on its own, the outcome is still likely to be good with treatment. Tear duct obstruction in adults has a variable outcome depending on the cause. Complications Tear duct blockage may increase the risk of eye infections. Call Your Health Care Provider If: Anyone with tear overflow onto the cheek requires examination, since one of the possible causes is tumor. Earlier treatment is more successful, and may be lifesaving.
Adults with obstruction require treatment of the cause of the obstruction. This may re-open the duct if there is minimal damage. Often surgical reconstruction (dacryocystorhinostomy) will be need to re-establish normal tear drainage and stop the overflow onto the cheek.
