Abstract
目的 探讨眼铁质沉着症的临床表现和发病机制.方法对因眼内异物引起的10例(10眼)眼铁质沉着症进行X线眼内异物定位检查,2例采用巩膜外磁性试验后牵引至睫状体平坦部吸出;2例晶状体异物行白内障囊外摘出合并后房型人工晶状体植入;6例行平坦部三通道闭合式玻璃体手术摘出异物,其中2例视网膜脱离行视网膜复位手术并注入硅油.结果2例晶状体异物的术后视力恢复到0.5和0.6;其余8例视力未见明显提高.2例玻璃体视网膜手术,分别于术后6、9月取出硅油,视网膜复位.结论眼内铁质异物存留所致的眼铁质沉着症后果严重,造成视功能的严重障碍,且异物摘出较困难,术后视力改善不理想.因此在临床上对有异物伤病史的患者,一定要排除眼内异物的存在,一旦发现眼内铁质异物,应尽快摘出,避免铁质沉着症的发生。
