方法：选取我院2010-01/2013-06收治的进行玻璃体切割联合球内异物取出术的球内异物患者47例48眼进行回顾性病例分析，包括视力的变化以及异物大小、术前并发症及就诊时间与视力的关系。

结果：所有患者中有46眼成功完整取出异物，2眼为眶内异物未予取出。术后6mo随访最佳矫正视力均有不同程度的提高(P<0.05)，球内异物大小、合并视网膜脱离是影响视力的危险因素(P<0.05)。

结论：玻璃体切割手术对治疗金属球内异物伤有明显的优越性，及时恰当的玻璃体手术对视功能的恢复尤为重要。

METHODS:Fourty seven cases(48 eyes)with foreign bodies from January 2010 to June 2013 in our hospital underwent vitrectomy combined with intraocular foreign body removal were retrospectively analyzed. The changes of visual acuity, the size of foreign body, the complications of preoperative, and the relationship between treatment time and visual acuity were recorded.

RESULTS: Totally 46 eyes were successfully removed the complete foreign body, 2 eyes of orbital foreign bodies had not been removed. After 6mo of followed-up, the best corrected visual acuity were all improved in varying degrees(P<0.05), intraocular foreign body size combined with retinal detachment was the risk factor for visual impact(P<0.05).

CONCLUSION:Vitrectomy has obvious advantages in the treatment of metal intraocular foreign bodies. Timely and appropriate vitrectomy is very important to the recovery of visual function.
