Introduction:
The standard surgical approach of unresponsive open angle glaucoma (OAG) has been classic trabeculectomy (CT). Non-penetrating deep sclerectomy (NPDS) is an alternative surgery in which a controlled filtration process is observed as a result of removing the inner wall of Schlemm's canal and juxta-canalicular trabecular meshwork where maximum flow resistance occurs. Our aim was to determine the influence of some of the factors associated with efficacy of NPDS.
Aim of the work:
To assess the influence of various preoperative, intraoperative and postoperative factors on the outcome of non-penetrating deep sclerectomy for Open Angle Glaucoma after a follow up of at least 2 years.
Materials and Methods:
This was a single arm retrospective study undertaken at Alexandria university in Egypt. Patients with open angle glaucoma who underwent NPDS with a minimum of 2year period of follow up were selected and the following variables were tested with a success criteria IOP of 12mmhg; age, preoperative and postoperative intraocular pressure (IOP), preoperative and postoperative number of medication, lens status (phakic or aphakic), history of other surgeries, intraoperative and postoperative complications, intraoperative and postoperative interventions and other glaucoma surgeries.
