A 78-year-old man underwent intracapsular cataract extraction with implantation of a Binkhorst four-loop lens. Two years later he developed recurrent hyphema, glaucoma, diffusion of blood into the vitreous, and reduction of visual acuity to 3/200. Iris fluorescein angiography demonstrated a localized network of prominent collateral vessels without fluorescein leakage above the pupil, deflection and compression of radial iris vessels by the superior lens posts, and a focal area of leakage adjacent to one of the posts. Argon laser photocoagulation obliterated the abnormal vessels in each of these areas, eliminated the recurrent hyphema and glaucoma, and permitted recovery of 20/80 visual acuity. The patient died suddenly three months after iris photocoagulation. Histopathologic study of the eye demonstrate erosion of iris stroma and displacement of iris vessels by the lens posts, as well as the vascular effects of successful photocoagulation therapy.
一名78岁男性接受了囊内白内障摘除术并植入了Binkhorst四环人工晶状体。两年后，他出现了反复前房积血、青光眼、血液扩散至玻璃体以及视力降至3/200。虹膜荧光血管造影显示，瞳孔上方有一个局部突出的侧支血管网络，无荧光素渗漏，晶状体上襻使虹膜放射状血管发生偏移和受压，且一个襻附近有一个局灶性渗漏区。氩激光光凝消除了这些区域中的异常血管，消除了反复出现的前房积血和青光眼，并使视力恢复到20/80。虹膜光凝三个月后，患者突然死亡。对该眼的组织病理学研究显示，虹膜基质被晶状体襻侵蚀，虹膜血管移位，以及成功的光凝治疗对血管的影响。
