The emphasis is on how to produce the best pictures, gather the maximum acoustic data, and interpret the echographic findings. In addition to examination techniques, the book also provides an overview of the clinical application of ultrasound, both in the eye and orbit. Many of these new and exciting applications have only become possible as a result of the recent innovations and developments in instrumentation. Methods of axial eye length measurement (biometry) and corneal thickness (pachymetry) are also described. Each chapter is referenced and there is a glossary of common technical jargon.
