Tear Drainage: Reconstruction by Implantation of a Glass Tube Prosthesis a.m. Lester T. Jones

Abstract

Good results are reported in patients with tear flow obstruction treated by implantation of a pyrex glass tube drain. Eight such drains were placed in seven patients with obstruction of the lacrimal canaliculi. Dependent drainage is established and this is aided by the negative pressure in the nose during inspiration.
