The purpose of this paper is to call attention to the necessity of using proper techniques and instrumentation in ultrasonography if the full value of this important diagnostic and research tool is to be realized.
The value of ultrasonography lies in its ability to yield high resolution cross-section views of the light-opaque portions of the eye and orbit. Cross-section views with high information content are obtainable only with techniques and equipment equivalent to those which we have reported.1,2
The authors have taken the position that permanently recorded cross-section views of the highest possible resolution and information content are mandatory for accurate diagnosis and for critical research investigations. Recently this position has been challenged by reports describing a wide range of ocular diagnoses, using a technique which yields data that is nearly impossible to interpret accurately and using equipment of poor resolving power.3-8 We feel that it is imperative
