眼内铁质异物并铁质沉着症的临床分析

目的探讨眼内铁质异物存留所致的眼铁质沉着症的诊断及手术治疗。方法回顾分析2006-02～2008-02收治的10例（10眼）因眼内铁质异物引起的眼铁质沉着症患者的临床资料。10例术前均行眼眶平片、眼部CT检查、A／B超检查，异物定位结果显示异物位于玻璃体内3例，位于球壁7例；采用睫状体平坦部三通道闭合式玻璃体手术摘出异物。结果10眼眼内铁质异物均一次手术取出，成功率达100％。其中术后视力改善7例（70％），无变化2例（20％），视力下降1例（10％）。结论眼内铁质异物存留所致的眼铁质沉着症后果严重，避免铁质沉着症的最好方法是眼外伤的患者应作全面而仔细的检查，一旦确诊眼内铁质异物，应尽早取净铁质异物，必要时施行玻璃体手术，尽量挽救视功能。

Clinical analysis on intraocular iron foreign bodies and ocular siderosis

Objective To investigate the diagnosis and treatment of ocular siderosis due to intraocular iron foreign bodies. Methods The clinical data of 10 patients with ocular siderosis due to intraocular iron foreign bodies were retrospectively analyzed, X-ray examnation, CT and A/B-utrasonic scan were used before operation. The foreign bodies located at vitreous in 3 patients and at wall of eyeball in 7 patients. The vitrectomy were adopted and the iron- foreign bodies were extracted. Results The iron-foreign bodies were extracted successly in all 10 patients. The visual function improved in 7 patients, no changed in 2 patients and descended in 1 patient after operation.
