AIM: To investigate the cause of the complications and suitable control measures of Ahmed valve implantation via anterior chamber for refractory glaucoma and to improve success ratio. METHODS: In the period from 2003 to 2005, a retrospective study of operative and postoperative application was based on 20 eyes which underwent Ahmed valve implantation via anterior chamber for refractory glaucoma. RESULTS: Follow-up was 4 to 23 months. Mean intraocular pressure (IOP) was lower from 35.32 mmHg to 18.64 mmHg. The outcomes of the study showed that the success rate was 90%. Thirteen cases (65%) were a complete success, including 4 cases which had early hypotony, 6 cases which had shallow anterior chamber, 4 cases which had anterior chamber hemorrhage, 3 cases which had obstruction of the drainage entrance, 1 case which had choroidal detachment. Five cases were not a complete success, including 3 cases which had fibrosis around Ahmed valve, 1 case which had superchoroidal hemorrhage, IOP lowering medications were still necessary. Two cases were failure for persistent high intraocular pressure. CONCLUSION: Despite the fact that complications happened frequently, we can also believe that refractory glaucoma Ahmed valve implantation via anterior chamber is a satisfactory and safe procedure if applied in time and with the appropriate control measures.
