超声生物显微镜对早期闭角型青光眼激光虹膜周边切除术后疗效观察

Evaluation of the Effectiveness of Laser Iridotomy for carly Primary

目的 :应用超声生物显微镜 (UBM)对早期闭角型青光眼激光虹膜周边切除术后疗效观察。方法 :应用 UBM对 2 8例 41眼早期闭角型青光眼激光虹膜周边切除术前后的观察 ,对激光虹膜周边切除术后房角增宽不明显的患者 ,局部点 0 .5 % pilocapine后再次复查 U BM。结果 :83%的急性闭角型青光眼激光虹膜周边切除后 ,可以达到治愈的目的 ,5 0 %的慢性闭角型青光眼激光虹膜周边切除术后 ,仍不能完全治愈 ,局部点 0 .5 %的 pilocapine可减少房角粘连的机会。结论

abstract Obfective to assess the effectiveness of laser iridotomy(LI)in the management of early primary angle￣closure glaucoma with ultrasound biomicroscopy(UBM) Methods 28 cases(4)eyes of early primary angle￣closure glaucoma were examed by means of UBM before and after LI The patlents whose drainage angles didnt become significantly wider after LI were topically trcated with 0.5%pilocarpine solution,then the drainage angles were examined with UBM once more. Result 83% of patients with acute primary angle￣closure glaucoma can be/were cured by means of LI.In contrast 50% of patients with cbronic primary angle￣closure glaucoma,involving varied pathogenesis,werent completely cured after LI,and need topical application of 0.5% pilocarpine eye drops to reduce the possbility of peripheral synechias Conclusion:It has an inportant role in the angle evaluation of patients with primary angle￣closure glaucoma after laser iridecloiny
