The history of the use of ultrasound in medicine has been one of evolution of technology and innovative methods of applying this technology to imaging body structures. Many scientists and clinicians have contributed to this evolution. Ophthalmic ultrasound has become an indispensible tool in ophthalmic practice, with its own instrumentation and techniques. Ultrasound frequencies used in ophthalmology have generally been higher than those used in general medicine because of a requirement for higher resolution and a lesser need for deep penetration. Most ophthalmic diagnostic equipment uses frequencies in the 10 MHz range. The use of ultrasound frequencies in the 50-100 MHz range is a relatively new development in ultrasound imaging of the eye. This technique has been developed in our laboratories over the past several years. We have progressed from the theoretical description of the basic science required, past the first in-vitro experiments in eye bank eyes, to the construction of an instrument capable of clinical application. We have gained broad clinical experience with this instrument in normal patients and patients with ocular disease. A commercial instrument based on our original clinical scanner has recently become available, allowing other clinicians to apply this tool to ophthalmic research and clinical practice. We have applied the term ultrasound biomicroscopy to this new imaging technique because of similarities to optical biomicroscopy, i. e. , the observation of living tissue at microscopic resolution.

Considered the definitive text in its field, revisions of the 2nd Edition reflect the latest advances in new technologies and most recent uses of ultrasound for intraocular and orbital lesions. Additional chapters delve into the use of high resolution ultrasound in identifying inflammatory diseases, tumors and glaucoma as well as color Doppler for diagnosing vascular disease. New illustrations in examination chapters will more fully explain and demonstrate techniques making this the most comprehensive source available.

In this book the author describes in detail the history, construction, and examination potential of the slit lamp. In particular, however, he presents a new approach – videography – that allows the ophthalmologist to document all eye diseases with the slit lamp and a video camera in a practicable, rapid, and affordable manner. The necessary methods, techniques, and equipment, including converging, diverging, and contact lenses, are clearly explained in the text and four didactic videos. The 20 most important videographic settings are described, and “recipes” for their use are presented, along with diagnostic tips. The accompanying collection of clinical images represents the world’s first ever general atlas of ophthalmology from the perspective of the slit lamp. It is the author’s hope that this introduction to ophthalmological videography, with its many images never previously produced with a slit lamp, will stimulate others to exploit the approach’s potential. ​

This book provides a visual overview of how to master ultrasonography and ultrasound biomicroscopy techniques. Updated ultrasonic information is included in a simple brief way, featuring didactic points, with a variety of documented scans and illustrated lines underneath for more clarification. Each pathology is accompanied with several scans of different findings to give more information of distinct detections. Ophthalmic Ultrasonography and Ultrasound Biomicroscopy: A Clinical Guide examines many clinical complexities with possible solutions when performing and interpreting ultrasound while also breaking down information for easier intake. The clinical cases are from a specialist eye hospital where many complicated cases are treated, giving a unique insight for the reader to understand treatment for a variety of cases. The book also emphasises the importance of everyday cases with further explanation whilst utilising a diversity of pictures and labels.

This book presents a new avenue in the field of ophthalmology and sheds light on the field of eye imaging. With the increasing availability of electronic devices and their important role in both personal and professional aspects of human life, there is a growing need for perfect vision. Ophthalmic imaging is a major tool for screening and documenting eye diseases in both medical and surgical fields of ophthalmology and is also of use for ophthalmologists around the globe. The number of eye-imaging devices has increased dramatically, however undiagnosed or poorly managed eye diseases remain a significant cause of ocular and visual problems worldwide. This essential guide addresses the need for a book that is dedicated to ophthalmic imaging, covering the cornea, glaucoma, retina and orbital imaging with updates on medical and surgical aspects of the topic.

In this thoroughly revised and updated third edition of Contact Lens Practice, award-winning author, researcher and lecturer, Professor Nathan Efron, provides a comprehensive, evidence-based overview of the scientific foundation and clinical applications of contact lens fitting. The text has been refreshed by the inclusion of ten new authors – a mixture of scientists and clinicians, all of whom are at the cutting edge of their specialty. The chapters are highly illustrated in full colour and subject matter is presented in a clear and logical format to allow the reader to quickly hone in the desired information. - Ideal for an optometrist, ophthalmologist, orthoptist, optician, student, or work in the industry, this book will serve as an essential companion and guide to current thinking and practice in the contact lens field. - Highlights of this edition include a new chapter on myopia control contact lenses, as well are completely rewritten chapters, by new authors, on keratoconus, orthokeratology, soft and rigid lens measurement and history taking.
