Abstract

Blockage could result from swelling around the internal portion of the nasolacrimal duct and the valve of Hasner, either after trauma or if the child had a cold. Both procedures are successful at improving the success of tear duct probing alone. Wagner: There are cases where I've had some difficulty retrieving the tip of the probe in the nose to pull the tube through. If it is tilted toward the back of the nose, sometimes you have to fish it out, but when I do it, it never takes more than a few minutes.
