无灌注玻切联合晶状体超声乳化及小梁切除治疗有晶状体眼的恶性青光眼

目的：探讨利用23 G微创无灌注玻璃体切割联合白内障超声乳化并小梁切除术治疗有晶状体眼的恶性青光眼的疗效,分析前后节复合手术治疗恶性青光眼的诊疗思路。
　　方法：有晶状体眼恶性青光眼患者21例21眼采用23 G玻切头进行前节玻璃体切割及玻璃体前界膜切开,玻切操作迅速且无需灌注及縫合,超声乳化人工晶状体植入联合小梁切除需进行晶状体后囊膜环形撕囊。术后观察视力、眼压、前房变化及术后并发症。
　　结果：术后3mo眼压从术前57.18±6.18mmHg降至16.15±2.43mmHg,两者差异有显著统计学意义(P<0.001)；术前房角深度为0.88±0.25mm,术后增至2.44±0.37mm,术后前房深度较术前显著加深(P<0.001)；术后视力较术前明显提高,无严重并发症发生。
　　结论：23 G微创无灌注前段玻璃体切割联合白内障超声乳化并小梁切除的复合手术方法,可以有效治疗有晶状体眼的恶性青光眼发作,恢复部分功能性视力。根据恶性青光眼发病机制及临床体征,进行早诊断、早发现、早治疗,前后节三联手术能有效控制并且能长时间维持稳定的眼内压。

Effect of 23G minimally invasive vitrectomy without irrigation in cataract ultrasonic phacoemulsification and trabeculectomy of phakic malignant glaucoma

AIM: To investigate the efficacy of 23G minimally vitrectomy without irrigation in cataract phacoemulsification and trabeculectomy of malignant glaucoma, and to analyze such compound operative procedures for phakic malignant glaucoma.

METHODS:A total of 21 phakic malignant glaucoma patients(21 eyes)underwent anterior vitrectomy without irrigation by using 23G vitrectomy. During surgical course phacoemulsification with anterior and posterior continuous circular capsulorhexis, trabeculectomy combined with iridectomy would be completed. Intraocular pressure, anterior chamber depth changes and postoperative complications were observed after the operation.

RESULTS:In the three-month follow-up, intraocular pressures were reduced from(57.18±6.18)mmHg to(16.15±2.43)mmHg, there was statistical difference compared with pre-operation(P<0.001). The preoperative anterior chamber depth(ACD)was(0.88±0.25)mm, the postoperative ACD was(2.44±0.37)mm 3mo later, there were significant difference(P<0.001). The best corrected visual acuity improved significantly, no serious postoperative complication appeared.

CONCLUSION:The compound surgical method of anterior vitrectomy combined with phacoemulsifier and trabeculectomy can effectively treat phakic malignant glaucoma. Early diagnosis and early compound surgery may effectively reduce the intraocular pressure of malignant glaucoma.
