激光虹膜成形术治疗早期慢性闭角型青光眼观察

摘要

AIM: To evaluate the safety of the laser peripheral iridoplasty ( LPIP ) for the early-stage chronic primary angle-closure glaucoma ( ECPACG) . METHODS:Sixty-five eyes of 36 patients with ECPACG received LPIP. At preoperative and postoperative, patients were examined with intraocular pressure ( IOP ) , anterior chamber, optical coherence tomography ( OCT) , visual acuity, visual field, fundus and complications. The mean follow-up was 18. 2±6. 7mo (ranged 12~24mo). RESULTS: The preoperative average IOP were 23. 8±5.6mmHg, postoperative 1wk, 1, 3, 6, 12mo and in the last follow-up time the average IOP were 18. 7±3. 8, 17. 9±3. 2, 17. 6±3. 5, 18. 4±3. 7, 18. 6±3. 7, and 18. 6±7. 8mmHg. There was statistical difference comparing with preoperative (P0. 05). The postoperative visual acuity, visual field, fundus had not changed. There were no complications found. CONCLUSION:LPIP is safe, and has the short time effect in the treatment of ECPACG. With elapse of time, the effect of LPIP is weakened. We can repeat the treatment.%目的：观察 Nd：YAG532激光虹膜周边成形术( Laser peripheral iridoplasty,LPIP)治疗早期慢性闭角型青光眼效果与安全性。　　方法：2011-09/2012-10内诊断为早期慢性闭角型青光眼患者36例65眼,行LPIP。术前术后观察眼压、前房角、视力、视野、眼底、并发症等情况。随访12~24(平均18.2±6.7)mo。　　结果：术前眼压23.8±5.6mmHg,LPIP术后1wk；术后1,3,6,12mo眼压分别为18.7±3.8,17.9±3.2,17.6±3.5,18.4±3.7,18.6±3.7mmHg,与术前比较差异全部具有统计学意义( P0.05)。术后随访时间内视力无变化,杯盘比无增大,视野损害无进展。　　结论：激光虹膜周边成形术治疗早期慢性闭角型青光眼安全,短期内有效,中长期效果有回退,可以重复治疗。
