This short handbook is specifically for the clinical opthalmologist who uses the Bronson-Turner Contact B Scan Ultrasonoscope. It gives the authors experience with this instrument in the techniques of examination and interpretation of findings in the eye and orbit.
The handbook is divided into two parts. The first part titled "The Basics" covers a brief concise history of ophthalmic ultrasound, an explanation of how this instrument works and its maintenance, and the technique of examination and explanation of ultrasonography in the normal eye and orbit. The second part is devoted to the clinical evaluation of the globe and orbit. It includes chapters on measurement of axial length, vitreous hemorrhage, asteroid hyalosis, retinal detachments, tumors, intraocular foreign bodies, the orbit, and artifacts.
It is a handbook and therefore brief and concise, which is an asset. However, there is no index, bibliography, or reference which is a limitation. In the authors' attempt to be concise, they assumed the reader had some background in B scan ultrasonography of the eye and orbit; therefore, they did not provide diagrams to explain many of their ultrasonograms. The authors recommend using the instrument on the lids instead of directly on the eye after topical anesthesia. This latter technique increases the sensitivity and resolution of the instrument. Many clinicians who follow their advice will be disappointed with the resolution of the instrument.
This handbook is very useful and to be recommended to everyone doing contact B scan ultrasonography with the Bronson-Turner unit. In a very concise manner, it covers all aspects of its advantages, limitations, and artifacts in the examination and diagnosis of eye problems. I found their advice sound and practical and their clinical presentations excellent.
