摘　　要：目的探讨虹膜根部离断修复手术治疗的新方法,并评价其手术疗效。方法在虹膜根部离断部位的周边角膜做0.5mm宽的隧道切口,以针心带线的4.5号针头经此切口进入前房,针尖穿过离断的虹膜根部后从相应部位的角巩缘穿出,引出针心内部分缝线,针尖退回前房后重复上述操作,如此反复行“锁边式”缝合,将相邻两针缝线在角巩缘处打结,虹膜根部离断即可修复。我们对31例虹膜根部离断患者按此方法行闭合式虹膜根部修复术的同时,对其合并症行Ⅰ期手术处理,观察其手术前后瞳孔形状、大小、居中性及视力的变化。结果31例患者虹膜根部离断完全修复,术后瞳孔形态、大小明显改善(X^2=12.68,P<0.05)。术后视力明显提高(!2=61,P<0.05),术后矫正视力≥0.2者24例(占77.42%),≥0.6者5例(占16.13%)。结论闭合式虹膜根部离断修复术操作简单、安全、方便、疗效满意,值得在临床推广应用。Objective To explore a new method for microsurgical repair of iridodiastasis and to evaluate its curative effect. Methods A 0.5mm channel was incised around the cornea near the iridodiastasis, a threaded syringe needle 4.5 size was inserted into the anterior chamber through the incision, the thread was drawn forth from the corresponding limbus after the needle passed through the iris. The above procedure was repeated after the needle entered the anterior chamber. The iridodiastasis was repaired after adjoining stitches were tied at the limbos. Microsurgical repair of iridodiastasis in the closed eyeball was performed on 31 cases. Complications were treated in the usual way. The shape, size and location of the pupils were observed and the visual acuity of the patients was measured. Results Iridodiastasis in the 31 cases was completely cured and the shape and size of the pupil clearly improved. The visual acuity of the patients greatly improved postoperatively, 24 eyes （77.42%） had a corrected visual acuity better than 0.2 and 5 eyes （16.13%） were better than 0.6. Conclusion Microsurgery can be easily and safely performed on the closed eyeball and it should be considered as a worthwhile procedure in the clinic.
