Seven cases of severe segmented uveal ectropion are presented. This is a color change of the iris which appears to be caused by pigment eipthelium being pulled from the pupillary margin to the footplates under a Tennant or Mark VIII anterior chamber lens. It was found in 1-2% of cases followed by the author for at least two to three years after lens implant. All eyes have poorly reactive pupils but seemingly well-fitting IOLs and good visual acuity to date. An hypothesis for its pathophysiology is presented which promotes ischemic atrophy with subsequent fibrosis of the iris as the involved mechanisms.
本文报告了7例严重的节段性葡萄膜外翻病例。这是虹膜的一种颜色变化，似乎是由于在Tenant或Mark VIII前房型人工晶状体植入后，色素上皮从瞳孔边缘被牵拉至脚板所致。在作者随访的晶状体植入后至少两到三年的病例中，有1%-2%出现了这种情况。目前所有患眼的瞳孔反应均较差，但人工晶状体似乎适配良好，视力也较好。本文提出了一种关于其病理生理学的假说，认为其涉及的机制是缺血性萎缩，随后导致虹膜纤维化。
