【摘要】 目的:探讨前房型Ahmed房水引流物植入术治疗难治性青光眼术中术后并发症的预防及处理,提高手术的成功率。方法:对2003/2005之间于我院行前房型Ahmed房水引流物植入后的20例难治性青光眼患者的术中术后并发症进行回顾性分析。结果:随访时间4～23mo。平均眼压水平由35.3±5.2mmHg(1mmHg=0.133kPa)降低至18.6±4.4mmHg,成功率为90%。13例完全成功(65%),包括早期低眼压4例、浅前房6例、前房积血4例、引流管口阻塞3例、脉络膜脱离1例;5例条件成功者(25%)包括引流盘周纤维化4例、暴发性脉络膜出血1例,仍需辅以降眼压药物控制眼压;2例因持续性高眼压导致失败。结论:通过前房植入Ahmed房水引流物术中术后并发症复杂多发,但经过及时妥善的处理仍可达到理想的疗效。更多还原

【Abstract】 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, 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 35.3±5.2mmHg to 18.6±4.4mmHg. The outcomes of the study showed that the success rate was 90%. Thirteen cases (65%) had completely success,including 4 cases had early hypotony, 6 cases had shallow anterior chamber, 4 cases had anterior chamber hemorrhage, 3 cases had obstruction of the drainage entrance, 1 cases had choroidal detachment. 5 cases had incompletely success, including 3 cases had fibrosis around Ahmed valve, 1 case had superchoroidal hemorrhage, IOP lowering medications were still necessary. Two cases were failure for persistent high intraocular pressure. CONCLUSION: Despite complications are complex and happened frequently, we can also believe that refractory glaucoma Ahmed valve implantation via anterior chamber is a satisfactory and safe procedure underwent timely and appropriate control measures.更多还原
