[Present status of locating intraocular foreign bodies (author's transl)].

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.
