Ultrasound oculometry (A mode) was performed in 30 eyes with three different standard equipments and great effort was made to make the three sets of measurements comparable. In spite of careful calibration procedures significant inter-equipment differences were found: anterior chamber depths and lens thicknesses showed the greatest discrepancies. These findings should be kept in mind when oculometric results of different authors are compared. A standardized eye-like phantom is desirable as a common reference for all who work in ultrasonic oculometry.

92 eyes have been examined with A-scan ultrasonography (8 MHz, Kretz-Technik apparatus 7100 MA and 7200 MA). Ultrasonic location of nonmagnetic and magnetic foreign bodies is compared to Comberg's radiographs and to intraoperative methods usch as stereoradioscopy or transillumination with the glass fiber diaphanoscope. Definitely corresponding results have been obtained in 60 cases. Ultrasonic location was difficult with small foreign bodies (reflecting surface less than 2 mm-2) within the orbit, the sclera, or within less than 2 mm from the sclera, as well as in severe vitreous clouding. Such cases should be evaluated with all location procedures available before considering further management.

BB shots and other spherical foreign bodies produce long chains of rapidly successive echo spikes which gradually decrease in height. These patterns are specific for this type of foreign bodies and allow their reliable detection and accurate localization. A-scan echography has become a very useful addition to X-ray examination in order to determine whether such foreign bodies are intra- or extraocular. Echography also helps to localize such foreign bodies during surgery and to evaluate the posterior segment of the eye in the presence of opaque ocular media (hemorrhages, cataract). Although it is sometimes possible to demonstrate specific B-scan patterns of spherical foreign bodies, A-scan echography is the method of choice since it is faster, more reliable and more accurate.
