目的：观察Ａｈｍｅｄ．Ｏｐｔｉｍｅｄ青光眼阀植入术治疗难治性青光眼的疗效及并发症。方法：对１５例（１６眼）难治性青光眼行青光眼阀植入术，其中植入Ａｈｍｅｄ阀９例１０眼，植入Ｏｐｔｉｍｅｄ阀６例６眼。结果：术后随诊１０－１６月平均１２．６±２．１月。Ａｈｍｅｄ阀：术前眼压５．４３±０．０９ｋｐａ，术后２．５９±０．７５ｋｐａ，Ｏｐｔｉｍｅｄ阀：术前眼压５．５１±０．８７ｋｐａ；术后５．４２±１．３９ｋｐａ，成功率分别为８０％、１７％，有显著差异，并发症包括术后早期低眼压、浅前房、引流口堵塞、引流管接触晶体或角膜、脉络膜脱离等。结论：Ａｈｍｅｄ．型青光眼阀植入术是治疗难治性青光眼的一种有效方法，而Ｏｐｔｉｍｅｄ型阀不应被选择。
Objective: To observe Ahmed. Optimed glaucoma valve implantation in the treatment of refractory glaucoma and complications. Methods: Glaucoma valve implantation was performed in 15 patients (16 eyes) with refractory glaucoma. 9 Ahmed valves were implanted in 10 cases and 6 cases in 6 cases. Results: The average follow-up of 10-16 months was 12.6 ± 2.1 months. Ahmed valve: preoperative intraocular pressure 5.43 ± 0.09kpa, postoperative 2.59 ± 0.75kpa, Optimed valve: preoperative intraocular pressure 5.51 ± 0.87kpa; postoperative 5.42 ± 1.39kpa, The success rates were 80% and 17%, respectively. There were significant differences between the two groups. Complications included early postoperative low IOP, shallow anterior chamber, blockage of drainage vents, drainage tube contact with crystals or cornea and choroidal detachment. Conclusion: Ahmed. Type of glaucoma valve implantation is an effective method of treatment of refractory glaucoma, and Optimed-type valve should not be selected.
