Objectives: To compare the intraluminal stenting and external ligation of Ahmed Glaucoma Valve (AGV) regarding refractory glaucoma management and postoperative hypotony prevention. Patients and Methods: This randomized clinical trial included 30 eyes of 25 patients (age range: 44-56 y) with refractory glaucoma. This study was conducted during the period from September 2018 to January 2020. The study included two groups, AGV with intraluminal stenting group (n=15) and AGV with external ligation group (n=15). Follow up continued to a year post operation. The primary outcome was Intraocular pressure (IOP) and its association with the number of postoperative glaucoma medications. IOP ≤ 21 mmHg without medications announced complete success while IOP ≤ 21 mmHg with medications indicated qualified success. IOP of \<6 mmHg defined hypotony.
