The Glaucomas by Roberto Sampaolesi,Jorge Zarate,Juan Roberto Sampaolesi Pdf

Congenital glaucoma is a complex problem, which has been a frequent cause of blindness in the past. Over the past decades, the prognosis of congenital glaucoma has completely changed. Surgical results are very good and enable these children to integrate entirely as adults in society. Based on the authors’ accumulated experience of more than 50 years and 860 cases operated for congenital glaucoma, this well-structured and lavishly illustrated textbook-atlas covers all aspects of congenital and infantile glaucoma, such as the original method for examining new-borns under general anaesthesia in the slit-lamp, the signs and symptoms of the disease and the differential diagnosis, the role and importance of the echometry value for early diagnosis, the gonioscopy results and the three types of congenital glaucomas (pure, refractory and late) and the type of surgery to be performed in each case with the evaluation of follow-up long-term results. Written by renowned international experts of the field, this book will become the golden standard in the field of Pediatric and Congenital Glaucomas.

Image Processing in Optical Coherence Tomography Using Matlab by Robert Koprowski,Zygmunt Wróbel Pdf

This book covers the results of the creation of methods for ophthalmologists support in OCT images automated analysis. These methods, like the application developed on their basis, are used during routine examinations carried out in hospital. The monograph comprises proposals of new and also of known algorithms, modified by authors, for image analysis and processing, presented on the basis of example of Matlab environment with Image Processing tools. The results are not only obtained fully automatically, but also repeatable, providing doctors with quantitative information on the degree of pathology occurring in the patient. In this case the anterior and posterior eye segment is analysed, e.g. the measurement of the filtration angle or individual layers thickness. To introduce the Readers to subtleties related to the implementation of selected fragments of algorithms, the notation of some of them in the Matlab environment has been given. The presented source code is shown only in the form of example of implementable selected algorithm. In no way we impose here the method of resolution on the Reader and we only provide the confirmation of a possibility of its practical implementation.

Anterior & Posterior Segment OCT: Current Technology & Future Applications by Ashok Garg Pdf

Optical coherence tomography (OCT) is a non-invasive imaging test that uses light waves to take cross-section pictures of the retina, the light-sensitive tissue lining the back of the eye (geteyesmart.org). Anterior segment OCT covers structures in front of the vitreous humour – iris, cornea, lens and ciliary body. Posterior segment OCT includes the anterior hyaloid membrane and all the structures behind it – vitreous humour, retina, choroid and optic nerve. This book is a comprehensive guide to the use of OCT in anterior and posterior segment surgery. Beginning with an introduction to the technique, the following chapters examine OCT for numerous different procedures including for corneal disorders, glaucoma, diabetic retinopathy, keratoconus and refractive surgery. The accompanying interactive DVD ROM demonstrates intraoperative use of OCT for different surgical procedures. Key points Comprehensive guide to OCT in anterior and posterior segment surgery Covers numerous procedures for different parts of the eye Interactive DVD ROM demonstrates intraoperative use of OCT Includes nearly 270 clinical photographs, diagrams and tables

Clinical Atlas of Anterior Segment OCT: Optical Coherence Tomography by Brett Levinson,Fasika Woreta,Kamran M. Riaz Pdf

While eye care providers are thoroughly familiar with the use of optical coherence tomography (OCT) in the diagnosis and management of glaucoma and retinal diseases, many are not as familiar with its myriad uses for the diagnosis of corneal and anterior segment conditions. Anterior segment OCT (AS-OCT) can help to differentiate between various corneal pathologies, show the anatomy of the angles, obtain information about the lens-capsule complex, and guide contact lens fitting, among many other clinical uses. Clinical Atlas of Anterior Segment OCT expertly guides clinicians through all aspects of AS-OCT with hundreds of high-quality OCT images that highlight the utility of AS-OCT in diagnosing and managing a wide spectrum of anterior segment diseases. Covers the entire normal anatomy of the anterior segment and pathology of the conjunctiva, corneal epithelium, stroma and endothelium, lens, iris, anatomic angle, and clinical settings such as trauma, infection, inflammation, and contact lens fitting. Includes information on using AS-OCT in clinical and surgical settings (intraoperative AS-OCT). Provides rich visual guidance with over 500+ high-quality figures (anterior segment OCT imaging and clinical photos) comparing normal anatomy and a wide range of pathology, including both common and rare disorders and how to differentiate frequently confused conditions. Provides a well-rounded perspective of AS-OCT, including how to use, understand, and capture images. Links high-quality slit lamp images to the corresponding AS-OCT image with clear labels to show the pathology side by side. Features clinical pearls in each chapter to relate key AS-OCT and clinical findings to everyday practice. An eBook version is included with purchase. The eBook allows you to access all of the text, figures, and references, with the ability to search, customize your content, make notes and highlights, and have content read aloud.

Optical Coherence Tomography in Glaucoma by Jullia A. Rosdahl Pdf

A comprehensive and user-friendly guide on leveraging OCT for the management of glaucoma Optical coherence tomography (OCT) is a noninvasive diagnostic imaging modality that enables ophthalmologists to visualize different layers of the optic nerve and retinal nerve fiber layer (RNFL) with astounding detail. Today, OCT is an instrumental tool for screening, diagnosing, and tracking the progression of glaucoma in patients. Optical Coherence Tomography in Glaucoma by renowned glaucoma specialist Jullia A. Rosdahl and esteemed contributors is a one-stop, unique resource that summarizes the clinical utility of this imaging technology, from basics to advanced analyses. The book features 14 chapters, starting with introductory chapters that discuss development of OCT and its applications for visualizing the optic nerve and macula. In chapter 5, case studies illustrate OCT imaging of the optic nerve, RNFL, and macula in all stages of glaucoma, from patients at risk to those with mild, moderate, and severe diseases. The next chapters cover the intrinsic relationship between optic nerve structure and function, the use of structure–function maps, and examples of their relationship, followed by a comparison of commonly used devices and a chapter on artifacts. Anterior segment OCT is covered next, followed by chapters covering special considerations in pediatric glaucomas and in patients with high refractive errors. The final chapters cover innovations in OCT on the horizon including OCT angiography, swept-source OCT, and artificial intelligence. Key Highlights Illustrative case examples provide firsthand clinical insights on how OCT can be leveraged to inform glaucoma treatment. In-depth guidance on recognizing and managing artifacts including case examples and key technical steps to help prevent their occurrence. Pearls on the use of OCT for less common patient scenarios such as pediatric glaucomas and high refractive errors. Future OCT directions including angiography, swept-source, and the use of artificial intelligence. This practical resource is essential reading for ophthalmology trainees and ophthalmologists new to using OCT for glaucoma. The pearls, examples, and novel topics in this book will also help experienced clinicians deepen their knowledge and increase confidence using OCT in daily practice.
