不同手术方式治疗新生血管性青光眼的临床观察

目的 观察不同手术方式治疗新生血管性青光眼（NVG）的疗效.方法 选择44例（44眼）新生血管性青光眼随机分为两组.（1）观察组：先用半导体激光封闭虹膜表面及前房角新生血管,次日行复合式小梁切除术 （2）对照组：经巩膜睫状体光凝术.两组术后均记录视力、眼压、虹膜新生血管及并发症情况,随访1年,对比两组的临床效果.结果 术后1年两组眼压较术前均下降,观察组眼压明显低于对照组,差异有统计学意义（P〈0.05）.观察组并发症较对照组少.结论 半导体激光虹膜光凝联合复合式小梁切除术及经巩膜睫状体光凝术均可作为治疗NVG的有效治疗方法,对于不同病情的NVG患者,可采取不同的手术方式进行治疗.

Clinical observation of different surgical treatment for neovascular glaucoma

Objective To observe the efficacy of different surgical treatments for neovascular glaucoma （NVG）. Methods Forty-four cases （44 eyes） with neovascular glaucoma were randomly divided into two groups. In the observation group, first semiconductor laser was used for the closure of neovascularization of the iris surface and anterior chamber angle, on the following day a combined trabeculectomy was performed. In the control group, transscleral cyclophotocoagulation was performed. In two groups postoperative visual acuity, intraocular pressure （IOP）, iris neovascularization, and complications were recorded. One year after operation the clinical effects of the two groups were compared. Results One year after operation IOP both groups in were decreased compared with the preoperative IOP; IOP in the observation group was significantly lower than that in the control group, the difference was statistically significant （P 〈 0. 05 ）. Complications in the observation group was lower than that in control group. Conclusion Semiconductor laser iris photocoagulation combined with compound trabeculectomy and transscleral cyclophotocoagulation may be u.sed as the effective methods for the treatment of NVG, and based on the different conditions of the NVG patients, the different surgical treatments may be used.
