Ultrasound of the Eye and Orbit

Abstract

Since ultrasound was first used in ophthalmologic practice in 1956, there have been at least nine publications that could be called text-books on the subject. This one is the most recent and, although comprehensive, is quite readable. The book quickly lets us know that the term<i>echography</i>is the most precise name for the field of study created by the evaluation of reflections of sound energy in the ultrasonic range. These reflections are displayed in various modes, including the time-intensity display known as the A mode and the two-dimensional intensity-space display known as the B mode. The book has three major sections. The first briefly and simply (perhaps too simply for some readers) reviews the principles of physics that underlie the science of echography. The second section deals with echography of the globe, devoting an initial chapter to a careful description of a systematic method of doing and recording an
