FP-7型与S2型Ahmed青光眼引流阀治疗难治性青光眼效果比较

目的比较FP-7型与S2型Ahmed青光眼引流阀治疗难治性青光眼的疗效及并发症有无差异。方法回顾性病例研究。分析于沧州市中心医院眼科分别行S2型（26例26眼）和FP-7型（23例23眼）Ahmed青光眼引流阀植入术的难治性青光眼患者的临床资料，对2组的眼压变化、手术成功率、术后并发症等进行比较。术前、术后眼压比较及2个观察组降眼压效果比较采用重复测量资料的方差分析；手术成功率的计算采用寿命表法，比较采用log-rank检验；并发症发生率的比较采用Fisher确切概率法。结果S2组术前眼压为（38.19±10.56）mmHg，术后1、6、12、24个月的眼压分别为（14.54±4.11）mmHg、（15.83±5.76）mmHg、（17.19±4.96）mmHg、（18.84±5.28）mmHg；FP-7组术前眼压为（39.91±9.12）mmHg，术后各时间点眼压分别为（14.41±5.14）mmHg、（15.95±4.32）mmHg、（17.11±4.75）mmHg、（19.06±6.55）mmHg。2组降眼压效果差异无统计学意义。至最后一次随访S2组的累积总成功率和累积完全成功率分别为82%和74%，FP-7组分别为80%和75%，2组比较差异无统计学意义。结论FP-7型与S2型Ahmed青光眼引流阀治疗难治性青光眼的降眼压效果相当，FP-7型的术后并发症发生率不高于S2型。

Comparison of FP-7 and S2 Ahmed glaucoma valve implantation in refractory glaucoma

ObjectiveTo compare the efficacy of using of FP-7 and S2 Ahmed glaucoma valve implantations （AGI） for refractory glaucoma and to monitor postoperative complications. MethodsA retrospective study was conducted to document patients with refractory glaucoma who underwent S2 （26 eyes from 26 patients） or FP-7 （23 eyes from 23 patients） AGI in the Center Hospital of Cangzhou. The change in IOP， the surgical success rate， and postoperative complications were recorded and analyzed. A variance analysis of repeated measurement data was used for comparison of preoperative and postoperative IOP and the effect of reducing IOP in the 2 observation groups. Cumulative survival rates were calculated using survival analysis and compared using a log-rank. The Fisher exact test was used for the comparison of complication rates. ResultsIOP was reduced from 38.19±10.56 mmHg to 14.54±4.11， 15.83±5.76， 17.19±4.96， and 18.84±5.28 mmHg at month 1， month 6， month 12， and month 24 postoperatively in the S2 group and reduced from 39.91±9.12 mmHg to 14.41±5.14， 15.95±4.32， 17.11±4.75， and 19.06±6.55 mmHg in the FP-7 group. There was no statistically significant difference between the 2 groups for their effect on lowering IOP. At the last follow-up， the cumulative probabilities of success and of total success were 82% and 74% in the S2 group， and 80% and 75% in the FP-7 group. There was no statistically significant difference between the 2 groups. ConclusionFP-7 AGI was equal to S2 AGI in reducing IOP in refractory glaucoma. The complication rate in the S2 group was no higher than it was in the FP-7 group.
