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.

Book Description
Publication Date: February 15, 2011 | ISBN-10: 1608456315 | ISBN-13: 978-1608456314 | Edition: 1
Fundus images of the retina are color images of the eye taken by specially designed digital cameras. Ophthalmologists rely on fundus images to diagnose various diseases that affect the eye, such as diabetic retinopathy and retinopathy of prematurity. A crucial preliminary step in the analysis of retinal images is the identification and localization of important anatomical structures, such as the optic nerve head (ONH), the macula, and the major vascular arcades. Identification of the ONH is an important initial step in the detection and analysis of the anatomical structures and pathological features in the retina. Different types of retinal pathology may be detected and analyzed via the application of appropriately designed techniques of digital image processing and pattern recognition. Computer-aided analysis of retinal images has the potential to facilitate quantitative and objective analysis of retinal lesions and abnormalities. Accurate identification and localization of retinal features and lesions could contribute to improved diagnosis, treatment, and management of retinopathy. This book presents an introduction to diagnostic imaging of the retina and an overview of image processing techniques for ophthalmology. In particular, digital image processing algorithms and pattern analysis techniques for the detection of the ONH are described. In fundus images, the ONH usually appears as a bright region, white or yellow in color, and is indicated as the convergent area of the network of blood vessels. Use of the geometrical and intensity characteristics of the ONH, as well as the property that the ONH represents the location of entrance of the blood vessels and the optic nerve into the retina, is demonstrated in developing the methods. The image processing techniques described in the book include morphological filters for preprocessing fundus images, filters for edge detection, the Hough transform for the detection of lines and circles, Gabor filters to detect the blood vessels, and phase portrait analysis for the detection of convergent or node-like patterns. Illustrations of application of the methods to fundus images from two publicly available databases are presented, in terms of locating the center and the boundary of the ONH. Methods for quantitative evaluation of the results of detection of the ONH using measures of overlap and free-response receiver operating characteristics are also described.
