Abstract

Introduction  Ultrasonography is an invaluable aid in the diagnosis and management of orbital disease because it can visualize and localize the position of orbital lesions when all other tests are negative. The soft tissues of the orbit may be examined with an instrument which has a resolving power of 0.2 mm. in depth by 0.3 mm. laterally.The appearance of the ultrasonogram differs from the other diagnostic records with which you are acquainted because ultrasound both penetrates and outlines soft tissues of the body. The ultrasonographic appearance of the normal orbit and a brief review of the technique of examination must be presented before proceeding with the case presentations of this paper.1Ultrasonography can best be understood by the ophthalmologist if it is described as slit-lamp microscopy of the eye in which high frequency sound has been substituted for the light source. The slit section is approximately 0.3 mm.
