The aim of the study is to compare postoperative outcomes and complications between Baerveldt Glaucoma Implant (BGI) and Ahmed Glaucoma Valve (AGV) implanted eyes with refractory glaucoma. This study included 48 eyes of 46 patients (BGI group) and 56 eyes of 52 patients (AGV group) who underwent BGI and AGV implantation, respectively, for the treatment of refractory glaucoma. Changes in intraocular pressure (IOP), medication score, and complications were evaluated postoperatively and compared between the BGI and AGV groups. The IOPs were significantly reduced after surgery in both groups, with significantly lower IOPs at 12, 18 and 24 months in the BGI group than in the AGV group (P < 0.05). Medication scores were significantly reduced postoperatively in both groups, with the AGV group having significantly lower scores than the BGI group at 1 week and 1 month (P < 0.05). Choroidal detachment caused by hypotony (P < 0.0005), additional glaucoma surgeries (P < 0.05) and tube exposure including Hoffman elbow due to the melting of the scleral flap (P < 0.01) were observed more frequently in the BGI group than in the AGV group. Prolapse or plate exposure caused by loosening of sutures was significantly more common in the AGV group (P < 0.05). BGI and AGV implantation effectively reduced the IOP and medication scores in eyes with refractory glaucoma, with subsequently lower IOP in the BGI group. The BGI group required more medication than the AGV group in the early postoperative period. These implantations have characteristic complications related to the nature of each device.
