超声乳化术治疗闭角型青光眼的临床观察

Clinical observation on the treatment of angle-closure glaucoma by phacoemulsification

目的观察超声乳化手术治疗闭角型青光眼的临床效果。方法回顾分析闭角型青光眼患者33例(38眼),抗青光眼术后患者8例(11眼),均在表麻下行经透明角膜隧道切口的白内障超声乳化联合折叠式人工晶状体植入术。结果眼压均得到控制,所有患者的眼压在21mmHg(1kPa=7.5mmHg)以下,31眼视力>0.5,术后视力、眼压、中央前房深度、房角与术前相比,均有显著性差异。结论对于闭角型青光眼的治疗,白内障超声乳化联合折叠式人工晶状体手术是一种便捷、安全、有效的方法,具有降压和增视的双重效果。

Objective To observe the clinical effect of phacoemulsification in the treatment of angleclosure glaucoma. Methods Retrospective study was conducted in 33 cases （38 eyes） with angle-closure glaucoma and 8 cases （ 11 eyes） with glaucoma which received filter operation. All the patients underwent topical anesthesia through limbal tunnel incision, the phacoemulsification and foldable intraocular lens implantation were performed. Results All the intraocular pressures were under the control and below the 21 mmHg（ 1 kPa = 7.5 mmHg）. The visual acuity was better than 0.5 in 31 eyes. After operation there were significant differences between the preoperative and postoperative in the visual acuity, the intraocular pressure, the central anterior chamber depth and the anterior chamber angle. Conclusion To treat the angle-closure glaucoma, phacoemulsification and foldable intraocular implantation is a kind of convenient,safe, valid method. At the same time it has dual results of decreasing the pressure and improving the visual acuity.
