Ultrasonography in foreign body detection and localization.
The relative advantages and disadvantages of radiographic and ultrasonic studies in foreign body detection and localization are discussed. The value of ultrasonography in finding radiolucent orbital foreign bodies and its clear superiority in the localization of foreign bodies with respect to the walls of the eye is demonstrated by several examples. The information concerning the state of the lens, vitreous, and retina in such traumatized eyes which is obtained by ultrasonography represents a very important additional benefit of such study.
