晶状体超声乳化吸除及人工晶状体植入术对闭角型青光眼眼压及前房深度的影响

目的评价品状体超声乳化吸除及后房型折叠式人工晶状体植入术或联合小梁切除术，治疗合并有自内障的闭角型青光眼，观察其术后眼压、前房深度及视力等的变化。方法回顾分析27例（30只眼）闭角型青光眼合并白内障患者。经综合降眼压治疗3～4d，眼压低于25mmHg者21只眼，即行巩膜隧道切口晶状体超声乳化吸除及后房型折叠式人工晶状体植入术，眼压高于25mmHg者9只眼，即行巩膜隧道切口晶状体超声乳化吸除及后房型折叠式人工晶状体植入联合抗代谢药物及小梁切除术。随访3—6个月。结果所有患者术中、术后没有出现严重的并发症，术后视力均有提高，术后眼压都得到控制。平均眼压由术前的20．28mmHg降至11．07mmHg；中央前房深度由术前的2．14mm加深到3．43mm。术后眼压、中央前房深度与术前相比均有显著性差异。术后前房角开放均≥180°。结论晶状体超声乳化吸除及后房型折叠式人工晶状体植入术或联合小梁切除术，是治疗合并有白内障的闭角型青光眼的有效方法。

Infection postoperative intraocular pressure anterior chamber depth on the treatment of angle-closure glaucoma by phacoemulsification and intraocular lens implantation

Objective To evaluate the clinical effect of phacoemulsification posterior chamber foldable intraocular lens implantation or combined with trabeculectmoy in the treatment of angle-closure glaucoma combined with cataract. To observation the variation of postoperative visual acuity intraocular pressure anterior chamber depth. Methods Retrospective study was conducted in 27 patients （30 eyes） with angle-closure glaucoma and cataract. After taking integrative drugs for reducing intraocular pressure for 3 -4 days, 21 eyes with intraocular pressure under 25 mm Hg accepted phacoemulsification posterior chamber foldable intraocular lens implantation,9 eyes with intraocular pressure over 25 mm Hg accepted phacoemulsification posterior chamber foldable intraocular lens implantation combined with antimetabolite and trabeculectmoy. All patients followed up 3 - 6 months. Results There were no severe complications occurred in the preoperative and postoperative . All the postoperative visual acuities were improved. All the intraocular pressures were under the control. The intraocular pressure was reduced from a preoperative mean of 20.28 mm Hg to a postoperative mean of 11.17 mm Hg. The mean central anterior chamber depth was 2. 14 mm preoperatively and 3.43 mm postoperatively. There were significant differences between the preoperative and postoperative in the intraocular pressure and the central anterior chamber depth. All the postoperative anterior chamber angle were opened more than 180°. Conclusion Phacoemulsification posterior chamber foldable intraocular lens implantation or combined with trabeculectmoy is an effective treatment method for angleclosure glaucoma combined with cataract.
