The different procedures used today to locate intraocular foreign bodies are discussed. The x-ray procedure is not adequate for splinters near the wall, questionable double perforations and foreign bodies which cannot be demonstrated radiographically. Complementary methods of examination such as transillumination, electroacustic location, ultrasonics and direct radio-optic controls must be used. Advantages and limitations of these individual locating procedures are discussed. Intensive transillumination with glass-fiber diaphanoscope is particularly important for splinters in the anterior section of the eyeball near the wall. Ultrasonics cannot be replaced by other methods for foreign bodies in the posterior section of the eyeball which do not produce shadows, demonstration of the relationship of the foreign body to pathologic intraocular structures and the measurement of the length of the eyeball. At the University Ophthalmic Hospital in Cologne, direct radio-optic controls are conducted with a stereo-x-ray image amplitier, a stereoscopic image that gives.
本文讨论了目前用于定位眼内异物的不同方法。X射线检查对于靠近眼球壁的碎片、可疑的双重穿孔以及无法通过X射线显示的异物并不适用。必须采用诸如透照法、电声学定位、超声检查和直接放射光学控制等辅助检查方法。文中讨论了这些单独定位方法的优缺点。使用玻璃纤维透照镜进行强化透照对于眼球前部靠近眼球壁的碎片尤为重要。对于眼球后部不产生阴影的异物、异物与眼内病理结构关系的显示以及眼球长度的测量，超声检查是其他方法无法替代的。在科隆大学眼科医院，使用立体X射线图像放大器进行直接放射光学控制，可提供立体图像。
