摘　　要：目的　探讨Nd∶YAG激光解除瞳孔膜闭的临床疗效。方法　应用Nd∶YAG激光对13例(13眼)前葡萄膜炎(活动性7例,陈旧性6例,其中复发者1例)并发瞳孔膜闭者行瞳孔膜切开术。自上方瞳孔缘作切口,借瞳孔扩大肌收缩力撕破瞳孔膜,扩大切口至瞳孔膜卷缩于前房内。术后抗炎、扩瞳、控制眼压、随诊。结果　术后1周视力05～12,平均077±011(x±s,下同),活动性炎症明显缓解,6例眼压异常者中4例恢复正常。术后1个月视力06～12(083±015),眼压全部正常。7例活动性炎症者中6例术后1个月炎症消失,1例术后2个月痊愈。除1例晶体遗留限局性击痕斑、4例出现短暂轻度眼压升高外,无其他并发症。结论　对强效扩瞳剂无法撕开的瞳孔膜行Nd∶YAG激光切开术,既能改善活动性前葡萄膜炎症状,减少并发症,又可显著改善患眼视力,经济、简便、快速、准确、安全有效,可收到事半功倍的效果。Objective To investigate the effect of Nd∶YAG laser on the occlusion of pupil. Methods The pupillary membrane incision was performed in 13 patients (13 eyes) with occlusion of pupil due to anterior uveitis (7 active cases and 6 static cases) by means of Nd∶YAG laser. The incision was started with the superior edge of the pupil. The pupillary membrane was torn by the contraction of the pupillary extensor. The incision was enlarged until the pupillary membrane rolled in the anterior chamber. Results The visual acuity was 0 77±0 11. Four out of 6 patients with abnormal intraocular pressure (IOP) returned to normal one week after laser irradiation. The visual acuity was 0 83±0 15 and all had normal IOP. Active inflammation in 6 patients disappeared one month after operation. One patient recovered 2 months after operation. The complications included localized pit of lens in one patient and transient and slight rising of IOP in 4 patients. All the rest were free from any complications. Conclusions Nd∶YAG laser can relieve the anterior uveitis and its complication, and can also improve the visual acuity in cases in which even the potent mydriatics failed to rip open the pupillary membrane. It's an economical, easy, rapid, accurate, safe and effective therapy which can get twice the result with half the effort.
