title: [Catheterization of the nasolacrimal duct].
abstract: A technique is described for passing a guide wire through the lacrimal duct into the nose following catheterisation of the duct. The wire is passed into the pharynx, a 7 F feeding tube is passed through the nose into the pharynx and these are then pulled out of the mouth with a Magill forceps. The tip of the feeding tube is then cut off and the guide wire introduced into a side hole of the catheter. By removing the catheter, the tip of the guide wire is pulled along and can be removed from the nose.
