High resolution B-scan ultrasonography is a valuable new technique in the diagnosis of orbital pathological conditions. This safe, atraumatic, and rapidly performed examination yields unique information as to the spatial relationships of softtissue structures in the orbit. This communication discusses the techniques used in B-scan ultrasonography of the orbit and describes in detail the ultrasonic appearance of the normal orbit so that pathologic deviations from the normal B-scan pattern can be recognized. Artifacts encountered in B-scan ultrasonography of the orbit are classified and described.
