title: [The use of ultrasound biomicroscope in the diagnosis of anterior segment intraocular foreign bodies].
abstract: OBJECTIVE
  To evaluate the use of Ultrasound Biomicroscope(UBM) in the diagnosis of anterior segment intraocular foreign bodies(IOFBs).
  
  
  METHODS
  Besides the rountine x-ray photography and B-scan ultrasound examination, 9 cases with difinite IOFBs injury history were examined by UBM.
  
  
  RESULTS
  Nine cases of IOFBs were shown in UBM image, among them 4 cases were invisible in x-ray photography and B-scan ultrasound examination. The IOFBs located in anterior chamber(1 case), in posterior chamber (2 cases), in pars plana (5 cases) and in iris root(1 case). The size of IOFBs varied from 0.1 mm x 0.25 mm to 1 mm x 3 mm. The IOFBs were extracted by combined intraocular surgery or direct magnetize extraction.
  
  
  CONCLUSIONS
  Although most IOFBs could be localized by X-ray and B-scan ultrasound, some located in the posterior chamber or ciliary body are hard to detect, especially when they are nonmetal and extremely small. The high resolution image of the anterior segment of the eye created by UBM can help to localize the IOFBs and show the relation between IOFBs and surrounding tissue, which is important in the diagnosis and the choice of surgery method.
