An 80-year-old woman with pseudoexfoliation syndrome developed subluxation of a posterior chamber intraocular lens (IOL)-capsular bag complex due to zonular rupture. She underwent a limited 25-gauge pars plana vitrectomy and iris transfixation of the subluxated IOL-capsule complex. The postoperative course was uneventful until the patient developed acute angle-closure glaucoma 3 weeks postoperatively. Ultrasound biomicroscopy confirmed pupillary block by the IOL-capsule complex. The patient was treated with intraocular pressure-lowering medications and a vitreous tap before a laser peripheral iridotomy could be performed successfully. The vision returned to normal, and the angle closure resolved. We recommend that a prophylactic surgical iridectomy be performed in patients with iris transfixation of a posterior chamber IOL-capsular bag complex.
一名患有假性剥脱综合征的80岁女性因悬韧带断裂导致后房型人工晶状体(IOL)-囊袋复合体半脱位。她接受了有限的25G经睫状体平坦部玻璃体切除术以及对半脱位的IOL-囊膜复合体进行虹膜贯穿固定术。术后过程平稳,直到患者在术后3周发生急性闭角型青光眼。超声生物显微镜检查证实为IOL-囊膜复合体导致的瞳孔阻滞。在成功进行激光周边虹膜切开术之前,患者接受了降眼压药物治疗和玻璃体穿刺。视力恢复正常,房角关闭得以解决。我们建议对后房型IOL-囊袋复合体进行虹膜贯穿固定术的患者进行预防性手术虹膜切除术。
