Abstract

We report a case of acute angle closure secondary to pupillary block caused by a dislocated intraocular lens (IOL)-capsular tension ring (CTR) complex. A 68-year-old woman, who had undergone cataract surgery 28 months earlier, presented with acute right eye pain and blurred vision. Examination revealed elevated intraocular pressure (IOP) of 80 mmHg, corneal edema, and anterior chamber shallowing, with anterior displacement of the IOL-CTR complex observed on anterior-segment optical coherence tomography. An anterior chamber paracentesis and subsequent vitrectomy were performed to remove the dislocated complex. After scleral fixation of a new IOL and management of an epiretinal membrane, the patient's vision improved, with her best-corrected visual acuity reaching 1.2 and IOP stabilizing at 18 mmHg without medication. This case highlights the potential for IOL-CTR dislocation to cause pupillary block and acute angle closure, emphasizing the need for timely diagnosis and comprehensive surgical intervention to preserve visual function.

摘要

我们报告了一例因人工晶状体（IOL）-囊袋张力环（CTR）复合体脱位导致瞳孔阻滞继发急性闭角型青光眼的病例。一名68岁女性，28个月前接受了白内障手术，现出现右眼急性疼痛和视力模糊。检查发现眼压（IOP）升高至80 mmHg，角膜水肿，前房变浅，前段光学相干断层扫描显示IOL-CTR复合体向前移位。进行了前房穿刺及随后的玻璃体切除术以取出脱位的复合体。在新的IOL巩膜固定及视网膜前膜处理后，患者视力改善，最佳矫正视力达到1.2，眼压在未用药情况下稳定在18 mmHg。该病例突出了IOL-CTR脱位导致瞳孔阻滞和急性闭角型青光眼的可能性，强调了及时诊断和全面手术干预以保留视功能的必要性。
