摘　　要：目的:探讨眼铁质沉着症的超声生物显微镜(UltrasoundBiomicroscopy,UBM)图像特征及异物的检出率。方法:应用UBM对16例眼铁质沉着症患者进行检查,分析UBM图像,同时与X线眼眶照片检查结果及手术结果进行对照。结果:16例眼铁质沉着症患者UBM检查均显示不同组织的铁锈沉着。X线眼眶照片显示异物残留者10例中,UBM检查显示异物残留者4例,X线检查未见异物残留者6例中,UBM检查显示异物残留者1例,手术取出异物11例。UBM显示异物图像为高强反射声影,有超声伪影,铁质沉着症的UBM图像特征为多发性点状、斑片状或线状高强回声、无超声伪影。结论:UBM能准确显示眼内异物位置及铁锈沉着部位,但异物的检出率较X线照片低。Purpose： To evaluate the characteristics of ultrasound biomicroscopy （UBM） image and the rate of positiveness of diagnosis for foreign bodies in siderosis. Methods： Sixteen cases of siderosis were examined with UBM and the data ware analyzed, compared with the data of X-ray and the record of operation. Results： The data of UBM showed deposition of rust in different tissues of eye-balls in the 16 cases of siderosis. Within the 10 cases of foreign bodies found by X-ray, only 4 cases were positive by UBM. X-ray data showed that the remaining 6 cases were negative of foreign bodies, but 1 case was found positive by UBM. The foreign bodies of the 11 cases were removed by operation. The characteristics of UBM images of foreign bodies displayed high and strong reflectivity with ultrasonic shadow, while the UBM image of siderosis showed multiple high and strong spot-like, speckled or thread-like shadows without ＂tails＂. Conclusion： UBM could detect the exact location of intraocular foreign bodies and rust. The positive rate of diagnosis for foreign bodies of UBM was lower than X-ray.
