方法：对41例41眼晚期新生血管性青光眼患者施行Ahmed青光眼引流阀植入术，术后观察随访12mo，记录术后1d； 1wk； 1，3，6，12mo的眼压并与术前进行比较，同时分析术后出现的并发症及其处理方法。

结果：本组病例术前、术后1d； 1wk； 1，3，6，12mo的平均眼压分别为59.83±5.53，19.27±8.19，19.69±6.86，20.67±6.73，21.05±6.93，21.49 ±7.42，22.14±8.08mmHg，术后各个时期眼压均较术前明显下降，经过统计学处理，差异有显著性； 手术并发症包括前房出血、前房延缓形成、引流管堵塞、引流盘包裹和暴露等。

结论：Ahmed青光眼引流阀植入术能显著降低眼压，并发症少，是治疗晚期新生血管性青光眼的有效方法。

METHODS: The Ahmed glaucoma valve were implanted in 41 eyes(41 cases)with late neovascular glaucoma, the follow-up was 12 months on average, intraocular pressure was recorded at 1 day, 1 week, 1 month, 3, 6, 12 months respectively after operation and compared with that before operation, at the same time, the complications and treatment were analyzed.

RESULTS: The mean intraocular pressure before operation, 1 day, 1 week, 1 month, 3, 6, 12 months after operation was 59.83±5.53, 19.27±8.19, 19.69±6.86, 20.67±6.73, 21.05±6.93, 21.49±7.42, 22.14±8.08mmHg, the mean intraocular pressure before operation was higher than that after operation and the difference was obvious in statistics. Major complications included hyphema, low intraocular pressure early postoperation, shallow anterior chamber, obstruction of the tube, the plate wrapped or exposed.

CONCLUSION: Ahmed valve implantation is an effective method to treatlate neovascular glaucoma.
