Permanent mydriasis can be a disabling condition. The author describes an iris cerclage running suture technique for the treatment of permanent mydriasis caused by diffuse iris sphincter damage. A long, curved transchamber needle on 10-0 polypropylene is passed in and out of the anterior chamber through limbal paracentesis openings while weaving the needle through the iris near the pupillary margin to form the cerclage. The technique minimizes stretching and distortion of the iris and creates a pupil that is precisely sized and rather round.
永久性瞳孔散大可能是一种致残性病症。作者描述了一种虹膜环扎连续缝合技术，用于治疗由弥漫性虹膜括约肌损伤引起的永久性瞳孔散大。使用一根10-0聚丙烯材质的长弯穿房针，通过角膜缘穿刺口进出前房，同时在瞳孔边缘附近的虹膜中穿梭，形成环扎。该技术可将虹膜的拉伸和变形降至最低，并形成大小精确且相当圆的瞳孔。
