摘　　要：目的探讨虹膜根部断离分度标准的科学性及改良的闭合式修复术在虹膜根部断离修复手术中的实用性。方法按虹膜根部断离的分度标准，将Ⅱ、Ⅲ度虹膜根部断离的18例（18眼），行改良的闭合修复术。即于虹膜根部断离的一侧端、角膜缘内透明角膜处、行平行于角膜缘的辅助切口，然后再按闭合锁边式缝合法进行缝合修复手术。结果这种分度的方法简单明了，便于临床和科研工作中的应用。使用改良的闭合修复方法，修复Ⅱ、Ⅲ度虹膜根部断离的18例，术后瞳孔圆形居中、圆及椭圆形者共17例，占94．4％。其中Ⅱ度11例，术后瞳孔椭圆居中者8例，占72．7％。3例瞳孔居中，但成椭圆型，占27．3％。Ⅲ度7例，术后4例瞳孔圆形居中，占57．1％，2例瞳孔居中成椭圆状，占28．6％。结论提出一个简单的虹膜根部断离程度进行分度标准，便于进行临床治疗和科研资料的比较。改良的虹膜根部断离修复术，是对虹膜根部断离闭合术式的一种补充，使手术更简单、方便和实用。Objective To investigate the scientificity of the iridodialysis grading standards and the practicability of the improved closed repair operation on the iridodialysis. Methods According to the grading standards, 18 eyes of 18 cases with Ⅱ or Ⅲ degree iridodialysis were treated with the improved closed repair operation. The auxiliary incision paralleling to the limbus was made on one side of the detached iris root, and then the iridic interruption was repaired with the closed continuous lockrand suture technique. Results The classification method was simple and clear which facilitated the application of the clinical research. Eighteen eyes of 18 cases with II or 11I degree iridodialysis received the improved closed repair operation. The pupils were circular, oval and mediate after the surgery in 17 cases, accounting for 94.4%. Of 11 cases with Ⅱ degree iridodialysis, the pupils were circular and mediate in 8 cases （72.7%） and were oval and mediate in 3 cases（27.3% ）. Of the other 7 cases with Ⅲ degree iridodialysis, the pupils were circular and mediate in 4 cases（57.1% ）, and were oval and mediate in 2 cases（28.6% ）. Conclusion The unified standards of describing iridodialysis were lacking at present. So that it is absolutely necessary to make a unified grading （degree） standards for iridodialysis to guide the clinical treatment and research. The improved repair operation is a complementary to the iridodialysis closed operation. It is much more simple and practical.
