Objective To study and discuss the clinical characteristics and treatment of ocular siderosis. Methods Seven patients (7 eyes) with ocular siderosis treated in Department of Ophthalmology of Xinqiao Hospi-tal from Jul.2012 to Dec.2014 were retrospectively analyzed.All patients underwent preoperative B-ultrasonogra-phy,ultrasond biomicroscopy(UBM),orbital CT examination and electrophysiological examination(ERG).Foreign bodies were located at the retina in 3 cases (3 eyes),at the pars plana in 3 cases (3 eyes) and at the anterior chamber angle in 1 case (1 eye).Foreign body in the angle of anterior chamber was removed in 1 case (1 eye). Six cases (6 eyes) underwent pars plana vitrectomy for the removal of foreign bodies,among them 3 cases (3 eyes) associated with retinal detachment received silicone oil injection after reattachment,2 cases (2 eyes) associated with cataract were performed phacoemulsification.Results All patients extracted the iron-foreign bodies successfully. The visual acuity was improved in 2 cases(2 eyes,28.6%),did not change in 3 cases(3 eyes,42.8%) and was de-creased in 2 cases(2 eyes,28.6%).Conclusion Ocular siderosis caused by iron foreign body severely influences the visual function.Patients with ocular trauma should be examined timely and carefully to reduce ocular siderosis. Once identified,the iron foreign body should be extracted immediately to avoid further damage of visual function.%目的：探讨眼铁质沉着症的临床特点及手术治疗。方法笔者回顾性分析2012年7月～2014年12月收治的7例（7眼）因眼内铁质异物所致的铁质沉着症患者临床资料，7例均为男性，年龄24～52岁，平均37.86岁。7例患者术前均行眼B超、超声生物显微镜（ UBM）、眼眶CT及电生理检查，其中3例（3眼）异物位于视网膜，3例（3眼）位于睫状体平坦部，1例（1眼）位于前房角。1例（1眼）行前房角异物取出术，6例（6眼）行平坦部三通道玻璃体手术摘除异物，其中3例（3眼）合并视网膜脱离患者视网膜复位后注入硅油，2例（2眼）合并并发性白内障患者行白内障超声乳化手术治疗。结果所有患者均一次取出异物，其中术后视力提高2例（2眼），占28.6％；无变化3例（3眼），占42.8％；视力下降2例（2眼），占28.6％。结论眼内铁质异物所致的眼铁质沉着症会造成严重的视功能障碍，眼创伤患者及时仔细的检查将减少眼铁质沉着症的发生，如若确诊，需尽早手术取出铁质异物，以避免视功能的进一步损害。
