The accurate detection and localisation of retained intraocular foreign bodies (IOFB) is important in the planning of subsequent surgical management. Using a porcine eye model, the authors have compared the relative detection rates of real time ultrasonography and plain roentgenograms for a variety of IOFBs. With an overall detection rate of 93%, ultrasonography appears to be a considerably more sensitive investigative tool than plain roentgenograms (40%) for the imaging of IOFBs, particularly those that are non-metallic.
眼内异物（IOFB）的准确检测和定位对于后续手术治疗方案的制定至关重要。作者使用猪眼模型，比较了实时超声检查和普通X线平片对各种眼内异物的相对检出率。超声检查的总体检出率为93%，对于眼内异物的成像，尤其是非金属异物，超声检查似乎是一种比普通X线平片（40%）更为敏感的检查工具。
