We report the findings in a 76-year-old woman who presented with a varix of the left iris that had manifested with hyphema. Slit lamp examination disclosed a circumscribed prominent round blood-filled lesion of the iris with smooth surface and surrounding hemorrhage. Examination with the laser flare-cell meter disclosed slightly increased flare of the left eye (10.2 photon counts/ms). Iris fluorescein angiography revealed a focal early circular hyperfluorescent area without leakage and a surrounding hypofluorescent area. Additionally, there was bilateral pseudoexfoliation. The iris varix showed complete regression during follow-up of two months. Possible etiological factors, including congenital or acquired changes of the iris vessels and alterations of the iris vessel walls in pseudoexfoliation syndrome, are discussed. Although varices of the iris are rare, they should be included in the differential diagnosis of prominent iris lesions.
我们报告了一名76岁女性的病例，该患者左虹膜出现静脉曲张并伴有前房积血。裂隙灯检查发现虹膜有一个边界清晰、突出的圆形充血性病变，表面光滑，周围有出血。激光散射细胞仪检查显示左眼散射略有增加（10.2光子计数/毫秒）。虹膜荧光血管造影显示早期有一个局灶性圆形高荧光区，无渗漏，周围有低荧光区。此外，还有双侧假性剥脱。在两个月的随访中，虹膜静脉曲张完全消退。文中讨论了可能的病因，包括虹膜血管的先天性或后天性改变以及假性剥脱综合征中虹膜血管壁的改变。尽管虹膜静脉曲张很少见，但在鉴别诊断突出的虹膜病变时应考虑到。
