Abstract
The Surgical Outcome of two Different Tear Drainage Tube in the Proximal Obstruction of Lacrimal System
Highlights
Complete proximal canalicular obstruction is one of the main cause of epiphora among patients complaining about ocular discomfort in their daily life [1]
This functional disturbance is traditionally treated by a lacrimal bypass surgery named conjunctivodacryocystorhinostomy (CDCR)
The purpose of this study is to evaluate and compare the efficiency of CDCR surgery with the use of tear drainage tubes with different material, such as silicone and Medpor coated
Summary
Complete proximal canalicular obstruction is one of the main cause of epiphora among patients complaining about ocular discomfort in their daily life [1] This functional disturbance is traditionally treated by a lacrimal bypass surgery named conjunctivodacryocystorhinostomy (CDCR). Thin Pyrex tubes provided excellent capillary attraction, low irritation to surrounding tissues, and a low risk of blockage; but as complication rates were still unacceptably high for some surgeons, new materials and techniques were developed [2] These developments, in patients with CDCR, the most common complications associated with tear drainage tube, are tube extrusion, malposition, obstruction, and diplopia [3]
