白内障超声乳化治疗闭角型青光眼的疗效

目的：评价白内障超声乳化联合人工晶状体植入治疗闭角型青光眼的适应证及临床效果。 方法：回顾性分析合并有白内障的首发急性闭角型青光眼，且房角关闭粘连范围<180°的患者16例18眼，单纯行白内障超声乳化联合人工晶状体植入手术，观察分析术前和术后眼压、前房深度、前房角及矫正视力的变化。 结果：术后眼压全部控制在20mmHg（1mmHg=0.133kPa)以下，前房深度明显增加，17眼最佳矫正视力均有不同程度的提高，1眼无变化。术中、术后无严重手术并发症。术后随访期间，17眼视力无明显变化，1眼因视网膜分支静脉阻塞引起眼底出血视力下降明显。术前和术后眼压、前房深度、最佳矫正视力差异有统计学意义（P<0.05）。 结论：恰当适应证的选择可使单纯超声乳化白内障治疗闭角型青光眼获得满意的临床效果。

Effect of phacoemulsification for cataract extraction in the treatment of angle-closure glaucoma

AIM:To investigate the effectiveness of phacoemulsification for cataract extraction in the treatment of angle-closure glaucoma(ACG). METHODS:Totally 16 cases(18 eyes)of acute ACG which had cataract and closed range of anterior chamber angle smaller than 180° received small incision cataract surgery with intraocular lens (IOL) implantation alone.Postoperative intraocular pressure (IOP), depth of anterior chamber,width of anterior chamber angle and visual acuity were observed with 1-12 months follow-up. RESULTS:IOP of 18 eyes was all under the control of 20mmHg(1mmHg=0.133kPa) 1 week after operation and the anterior chamber angles became wider.Best-corrected visual acuity acquired increase in 17 eyes at different degrees.1 eye had no changes. There was no serious operation complication.During the follow-up time IOP of 17 eyes had no change compared to postoperative 1 month.Eyesight of 1 eye decreased because of fundus hemorrhage.The preoperative and postoperative IOP,anterior chamber depth and sight had statistically significant differences. CONCLUSION:With the proper selection of indications,the clinic effect of phacoemulsification for cataract extraction in the treatment of ACG was satisfactory.
