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 :对闭角型青光眼激光虹膜周边切除术后的房角再评价十分重要 Objective: To observe the curative effect of UBM after laser iridectomy in early angle-closure glaucoma. Methods: UBM was used to observe the changes of laser iris before and after laser ablation in 28 cases of 41 patients with early-angle-closure glaucoma. In patients with no obvious widening of angle after laser iridectomy, local point was 0. 5% pilocapine Review U BM. Results: After 83% of acute angle-closure glaucoma laser iris resection, the curative effect can be achieved. After the excision of 50% of the patients with chronic angle-closure glaucoma laser iris, it still can not be completely cured, and the local point is 0.5% Pilocapine can reduce the chance of adhesion. Conclusion: It is very important to re-evaluate the angle after laser iris peri-angle excision of angle-closure glaucoma
