ONE OF the many uses of polyethylene tubing is its employment in the management and restoration of the lacrimal canaliculi, as described by Henderson,* of Rochester, Minn.
In using the tubing for this work, I employ the size described as 1D.034-1D.060-100ft-PE100. For restoration or construction of new canaliculi, in cases of atresia and scarring following accidents, the tubing is passed from the punctum through the canaliculus and then through the nasolacrimal duct into the nose. One of the problems connected with the use of this tubing is sewing the edge of the tubing into the canaliculus. The sutures tend to come untied and occasionally need tightening. Also, there is an added irritation from these sutures that would be eliminated if the sutures could be discarded. In my last case the tubing was left in for 47 days. Hoping to improve the method of using this tubing, I have had some
