To evaluate the epidemiologic factors, associated ocular involvement and visual results in patients with intraocular foreign bodies lodged in the posterior segment.
In this retrospective study, the clinical records of 21 patients admitted to the hospital with intraocular foreign bodies between August 1994 and March 1998 were reviewed and evaluated in regards to age, gender, type of injury, foreign body nature, need for surgical intervention, complications and final visual acuity.
All the patients were males, with a mean age of 38.7 years and an average follow-up period of 15.04 months. The foreign bodies were caused by work accidents in 2/3 of the cases and 71.4% involved ferromagnet metal. Sixteen patients underwent vitrectomy to remove the intraocular foreign body. Final visual acuity was equal to or greater than 0.4 in 57.9% of the patients and there was no light perception in 15.7%. The principal late complications were retinal detachment (19.04%), pthisis bulbi (14.2%) and cataracts (9.5%).
Most of the intraocular foreign bodies are found in young males as a consequence of work accidents. Most patients require vitrectomy to remove the foreign body and even though good visual results are obtained in many cases, other cases suffer severe visual loss.
评估后段眼内异物患者的流行病学因素、相关眼部受累情况及视力结果。
在这项回顾性研究中，对1994年8月至1998年3月期间因眼内异物入院的21例患者的临床记录进行了回顾，并对年龄、性别、损伤类型、异物性质、手术干预需求、并发症及最终视力进行了评估。
所有患者均为男性，平均年龄38.7岁，平均随访期15.04个月。三分之二的病例中异物由工作事故导致，71.4%涉及铁磁性金属。16例患者接受了玻璃体切除术以取出眼内异物。57.9%的患者最终视力等于或大于0.4，15.7%的患者无光感。主要的晚期并发症为视网膜脱离（19.04%）、眼球痨（14.2%）和白内障（9.5%）。
大多数眼内异物见于年轻男性，是工作事故的结果。大多数患者需要进行玻璃体切除术以取出异物，尽管在许多病例中可获得良好的视力结果，但其他病例会出现严重的视力丧失。
