Purpose. Ocular siderosis (OS) is a sight threatening complication of retained iron-containing Intraocular Foreign Body (IOFB). Successful localization of the IOFB and timely removal are crucial to its management. The purpose of this study was to review the presentation, management, and outcome of OS at our institution. Methods. A retrospective case series of eyes with OS that underwent IOFB removal from January 2009 to March 2015 at our institution. Results. OS was seen in 9 eyes of 9 patients during the study period. There were 8 males and 1 female with an age range of 31.6 years. An IOFB was in all the eyes. The most common features of siderosis were cataract and pigmentary retinopathy seen in 6 (67%) and 4 (44%) eyes, respectively. Electroretinogram (ERG) readings were reduced in the 9 eyes. The IOFB was removed by pars plana vitrectomy in all the cases with improvement in ERG amplitudes occurring postoperatively in 7 (78%) eyes. Conclusion. A retained iron-containing IOFB can manifest itself after several years with features of OS. A careful clinical and radiologic evaluation is imperative in patients with history suggestive of penetrating ocular injury to rule out retained or occult IOFB and thus prevent this catastrophic condition.
目的。眼铁质沉着症（OS）是眼内异物（IOFB）残留且含铁所导致的一种威胁视力的并发症。成功定位IOFB并及时取出对其治疗至关重要。本研究的目的是回顾我院OS的临床表现、治疗及预后。方法。对2009年1月至2015年3月在我院接受IOFB取出术的OS患者进行回顾性病例系列研究。结果。研究期间，9例患者的9只眼出现了OS。其中男性8例，女性1例，年龄范围为31.6岁。所有眼中均有IOFB。铁质沉着症最常见的特征分别为白内障和色素性视网膜病变，分别见于6只眼（67%）和4只眼（44%）。9只眼的视网膜电图（ERG）读数均降低。所有病例均通过玻璃体切除术取出IOFB，术后7只眼（78%）的ERG振幅有所改善。结论。残留含铁的IOFB可能在数年后表现出OS的特征。对于有穿透性眼外伤史的患者，必须进行仔细的临床和影像学评估，以排除残留或隐匿的IOFB，从而预防这种灾难性情况。
