Clinical Ophthalmic Echography

The second editon of this popular ultrasound book expands the reader's understanding of the clinical applications of ocular ultrasound through a case study approach. With the addition of high-quality video segments of examination techniques not currently available in any other format, this edition appeals to a broader range of practitioners in the field by presenting the subject starting at the basic level and progressing to the advanced. The book is appealing to practitioners involved in ocular ultrasound, including ophthalmic technicians, ophthalmologists, optometrists, radiologists and emergency room physicians who, on occasion, are involved in the practice of ophthalmic ultrasound.

The second edition of this book expands the reader's understanding of the clinical applications of ocular ultrasound through a case study approach and aims to provide a firm foundation in the fundamental examination techniques and applications of ophthalmic echography.

Ultrasonography is an important adjuvant for the clinical assessment of a variety of ocular and orbital diseases. With proper use, one can gather a vast amount of information not possible with physical exam alone. Ultrasound is most useful when intraocular are difficult or impossible to examine. Situations that prevent normal examination include lid problems (severe edema, partial or total tarsorrhaphy), keratoprosthesis, corneal opacities, hyphema, hypopyon, miosis, pupillary membranes, dense cataracts, or vitreous opacities (hemorrhage, inflammatory debris). Diagnostic B-scan ultrasound accurately images intraocular structures and give valuable information on the status of the lens, vitreous, retina, choroid, and sclera. Ultrasound is also used for diagnostic purposes when pathology is clinically visible, such as differentiating iris or ciliary body lesions; ruling out ciliary body detachments; differentiating intraocular tumors, serous versus hemorrhagic choroidal detachments, rhegmatogenous versus exudative retinal detachments, and disc drusen versus papilledema; or determining functioning versus nonfunctioning glaucoma tube shunts.

There have been significant advancements in the field of ophthalmic ultrasound as this imaging technology can now detect and differentiate minute lesions in a wide variety of eye disorders. With understanding of the indications for ultrasonography and proper examination techniques, one can gather a vast amount of information not possible with a clinical exam alone. Clinical Atlas of Ophthalmic Ultrasound includes a short clinical description of each case presented and supplemented with high quality, color fundus images, wide-field images, CT/MRI scans, and/or pathologic slides where applicable. Written for ophthalmologists, radiologists, echographers, and ophthalmic oncologists, this book offers more of a comprehensive clinical view on a particular disease, including multimodal imaging approach, rather than just ultrasound characteristics. Chapters covering clinical and surgical globe anatomy, vitreo-retinal disease, trauma, intraocular tumors, and optic nerve disorders are all included.

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 the latest information on using echography to diagnose lesions and diseases of the eye and orbit. This edition is fully updated, with a new chapter on orbital disease and coverage of the 20-MHz probe for posterior segment imaging. It provides a comprehensive review of the basic screening procedures, descriptions of the indications for ultrasound, and guidance on how to reach an accurate diagnosis of both common and rare clinical problems in all areas of the eye. Features: Techniques for diagnosing diseases of the retina, choroid, vitreous, anterior segment, optic nerve, extraocular muscles, and more More than 550 high-quality images, including an expanded collection of anterior segment images, that aid the comprehension of pathology and disease processes Three-dimensional schematics demonstrating sound beam and probe positions on the eye Extensive lists of references for pursuing topics in depth Ophthalmic Ultrasound: A Diagnostic Atlas will provide an invaluable reference for ophthalmologists, ultrasonographers, and radiologists.

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. Features 5 brand-new chapters: Inflammatory Diseases of the Eye, Glaucoma, Ultrasound Biomicroscopy of the Eye, Three-Dimensional Ultrasound of the Eye, and Color Doppler Imaging of the Eye and Orbit. Offers expanded discussions of axial eye length measurements-the most common use for ultrasound in ophthalmology. Includes a new, 4-page color insert that highlights color Doppler findings. Revises both information and illustrations for the most up-to-date examples in the field.
