title: [Clinical analysis of huge intraocular foreign body extraction in seventeen cases].
abstract: OBJECTIVE
  To discuss the definition of huge intraocular foreign body (IOFB), the selection of operation and the improvement of cure rate.
  
  
  METHODS
  (1) The foreign body was localized by X-ray, and extracted through sclera; (2) direct localization by indirect ophthalmoscope; (3) extraction of IOFB in combination with pars plana vitrectomy (PPV); (4) extraction through anterior chamber.
  
  
  RESULTS
  The IOFBs were extracted successfully in all cases. The foreign bodies of 13 eyes were extracted in combination with PPV (72.2%, secondary enucleation with coral porous hydroxyapatite implantation was performed on one case later), and extracted through sclera in 5 eyes. Post-operative visual acuity was improved in 6 eyes, not changed in 9 eyes and decreased in 3 eyes.
  
  
  CONCLUSIONS
  IOFB extraction in combination with PPV is less damaging, accurate and safe, that reduces the complications and enhances the cure rate. It is worth to popularize.
