摘　　要：【摘要】目的观察改良的虹膜根部断离的修复方法一单弯针经角膜连续缝合法的疗效。方法使用10-0聚丙烯缝线的双弯针中一个带线弯针，从断离区角膜缘后1．5mm处巩膜进针入前房，穿过断离的虹膜根部，在角膜缘内2mm处出针，再反转该弯针从原角膜出针口进针入前房，在距第一针虹膜进针点1．5～2mm处反穿虹膜，再从距原巩膜进针点2～3mm处巩膜出针，以同样方法连续缝合断离的虹膜根部。结果连续治疗7例，虹膜断离均复位，术后圆形瞳孔6例，梨形瞳孔1例，视力均较术前提高，无单眼复视。结论以带10．0线的单弯针经角膜连续缝合修复虹膜根部断离的方法易于掌握，能较准确地缝合断离的虹膜根部，损伤小，手术时间短，效果较好。Objective To observe the efficacy of continous suture technique with 10-0 polypropylene single curved needle by passing through cornea in the treatment of traumatic iridodialysis. Methods One double curved needle with 10-0 polypropylene suture penetrated into the anterior chamber through the sclera at l. 5 mm behind the limbus. The suture passed through the root of the separated iris and came out of the chamber through the cornea at 2mm inside the limbus. Then the needle went into the same corneal point and passed through the iris at 1.5-2 mm away from the first iridal point, then went out of the chamber at 2-3 mm away from the first scleral point. This same surgical procedure was applied in the eontinous suture of the detached iris. Results Seven cases of traumatic iridodialysis were treated by this procedure. After surgery,the shape of pupil was round in 6 cases and pear-shaped in one case. The vision was improved in all cases and no monodiplopia was observed. Conclusion This single curved needle with 10-0 polypropylene continuous suture technique is effective for the repair of traumatic iridodialysis, which with few surgical damage and short time of surgery.
