AIM: To investigate the effect of vitrectomy in treatment of metal intraocular foreign bodies and the factors affecting visual prognosis.

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.
