—In the December 1970 issue of the Archives (84:765), in the Surgical Techniques section, Dr. Richard Tenzel describes a "new" technique for treatment of obstruction of the common canaliculus.First of all, the technique is not new, having been described by Drs. B. Jones and L. T. Jones, in their respective chapters on canalicular disorder in Corneo-Plastic Surgery: Proceedings of the Second International Corneo-Plastic Conference, London, Pergamon Press Ltd, New York, 1969. Secondly, where an obstruction exists, it is common sense to relieve the obstruction where possible, rather than bypass it. In the third place, I do not see how the canaliculi remain patent, without the temporary aid of an indwelling polyethylene tube, or a suture left in place for one to two months.My experience has been that the canaliculus closes, if the above measures are not used.
