Injection of contrast mediums into Tenon's capsule, as described by Spackman,1 has proved invaluable in the localization of intraocular foreign bodies. This is especially true of the type of injury incurred in jungle warfare, in which hand grenades, booby traps and small antipersonnel mines are used extensively. These usually cause multiple, small, penetrating wounds, containing opaque foreign bodies of varying sizes, which roentgenographically look like "snow flurry" collections of opaque debris. When the region of the eye is involved, it is frequently impossible to distinguish intraocular foreign bodies from those outside the eyeball by any procedure except roentgenographic study with injection of a contrast medium into Tenon's capsule (fig. 1). This method is also of considerable assistance in the localization of foreign bodies lying near the limits of the globe and in diagnosing double perforations of the eyeball.
