【摘要】 目的:评价后巩膜开窗减压术在治疗绝对期青光眼中的应用。方法:对43眼绝对期青光眼施行后巩膜开窗减压术,与38眼行睫状体冷冻术患者术后早期(2mo内)眼压变化进行对比。结果:行后巩膜开窗减压术病例术后高眼压症状明显缓解,术后早期眼压不反弹,较施行睫状体冷冻术者控制眼压疗效好(P<0.01),且无严重并发症。 结论:后巩膜开窗减压术是治疗绝对期青光眼更简便、安全、有效的手术选择。

AbstractAIM: To evaluate the curative effect of posterior scleral marsupialization on absolute glaucoma.METHODS: Fourtythree patients of absolute glaucoma were operated with posterior scleral marsupialization. Thirtyeight patients were treated with cyclocryotherapy. The intraocular pressures was observed for 3 years and compared two groups in 2 months after operation.RESULTS: Posterior scleral marsupialization was especially advantageous to control the abnormal intraocular pressures in early stage after operation. It was more effective than the treatment with cyclocryotherapy (P<0.01).CONCLUSION: The operation is a simple, safe and effective choice in treating absolute glaucoma.
KEYWORDS: absolute glaucoma; posterior scleral; marsupialization
0引言
近几十年来各种原因引起的绝对期青光眼多以睫状体冷冻术作为治疗的最后措施,其长期疗效得到肯定[1]。但此术式术后早期眼压下降常不满意,高眼压状态的持续,给患者带来痛苦。我们以后巩膜开窗减压术治疗此类病例,随访最长达3a,发现临床效果特别是术后早期(2mo内)疗效相当满意,现作初步报道。
1对象和方法
1.1对象
搜集1998/2007年绝对期青光眼病例81眼(包括原发性青光眼、继发性青光眼等)。行睫状体冷冻术者以2002年前为主,共计38眼,作为Ⅰ组。其中男18眼,女20眼,年龄30~80岁。术前眼压37.6~66.9mmHg。行睫状体冷冻术联合巩膜穿刺术者以2002年后为主,共计43眼,作为Ⅱ组。其中男25眼,女18眼,年龄32~81岁。术前眼压为29.4~71.7mmHg。经SPSS 11.1统计学软件处理,两组资料早期(2mo内)疗效有显著性差异(P<0.05)。
1.2方法
手术均在显微镜下进行。做下直肌吊线向上方牵引固定,以1mL注射器于3∶00位角巩膜缘穿刺进前房,抽取房水约0.1mL降低眼内压,在颞下方角膜缘外2mm处作一6mm弧形结膜切口平行角巩膜缘,两端向后作放射状剪开,暴露颞下方巩膜,在赤道部后巩膜上作一6mm×6mm全层窗口或等边三角形孔,深达脉络膜。用微型虹膜恢复器剥离窗口(或孔)边缘的脉络膜,至孔缘约3~5mm,造成人为脉络膜脱离,连续缝合球结膜。术毕结膜下注射地塞米松2.5mg,术眼加压包扎,24h后换药。
