摘要
目的探讨氩激光周边虹膜成形术治疗药物降眼压效果不理想的急性闭角型青光眼的临床疗效。方法对我院确诊的26例(27眼)急性闭角型青光眼,使用降眼压药物治疗后眼压仍然高于正常时,于前房角镜下行氩激光周边虹膜成形术。手术方法:术前缩瞳,眼球表面麻醉下在虹膜根部进行光凝,范围360度,平均约50个激光斑。结果术前眼压为33～69mmHg(平均51mmHg),术后1h眼压为26～49mmHg(平均36mmHg),平均眼压下降15mmHg,下降幅度29.4%;术后2h眼压为19～34mmHg(平均27mmHg),平均眼压下降24mmHg,下降幅度47.1%;术后24h眼压为12～30mmHg(平均20mmHg),平均眼压下降31mmHg,下降幅度60.8%;术后24h最佳矫正视力0.08～0.4,较术前指数/30cm～0.2明显提高。结论原发性闭角型青光眼(PACG)急性发作期使用药物降眼压效果不理想时,行激光周边虹膜成形术使关闭的房角开放,粘连减少,降眼压效果明显。
Objective to investigate the effect of argon laser peripheral iridoplasty （ALPI） for acute angle-closure glaucoma that were unresponsive to drug therapy. Methods 26 cases （27 eyes） of acute angle-closure glaucoma that were unresponsive to drug therapy were treated by ALPI under gonioscopy. Surgery methods： after receiving topical pilocarpine （4%） and topical anaesthesia, the subject eyes underwent ALPI at the iris root in all 360 degrees and had 50 laser spots on average. Results preoperative intraocular pressure （IOP） was 33-69 mmHg （51 mmHg on average）. The IOP range and average values of one hour, two hours and 24 hours postoperatively were 26-49 mmHg （36mmHg）, 19-34mmHg （27 mmHg） and 12-30 mmHg （20 mmHg） respectively, the decrease values and percentages of IOP were 15 mmHg （29.4%）, 24 mmHg （47.1%） and 31 mmHg （61.8%） respectively. The 24-hour postoperative best corrected visual acuity was 0.08-0.4 which was a significant increase compared with the preoperative values of finger counting/30 cm-0. 2. Conclusion Laser peripheral iridoplasty could significantly decrease the IOP of PACG patients who are experiencing acute attacks and are unresponsive to drug therapy by effectively reopening the closed anterior chamber angle, and by decreasing the amount and extent of anterior synechiae.
