This handbook covers Optical Coherence Tomography Angiography (OCT-A) with a specific focus on choroidal and vitreoretinal disorders. It serves as an invaluable resource for teaching and aiding daily clinical decision-making in the field. Book chapters dissect the fundamentals of angiography through OCT, offering guidance on OCT-A and insights into macular perfusional findings across various vitreoretinal and choroidal pathologies. From diabetic retinopathy to autoimmune diseases and neovascularization, the book addresses prevalent vascular entities encountered in routine practice. Furthermore, it explores innovative approaches, including antivascular endothelial growth factor molecules and extended-release delivery devices, contributing significantly to the diagnostic and decision-making processes in clinical and surgical retina care. Each chapter is contributed by experts in the relevant subspecialty. Key Features: Practical, patient-centered guide emphasizing a clinical approach. Demonstrative clinical cases for enhanced understanding. Evaluation of perfusional indices using noninvasive and noncontact imaging techniques. High histopathological correlation of structural tissue characterization with microvascular evaluation. Exploration of new perfusion concepts and their role in disease pathogenesis. Part 1 of the book focuses on OCT-A principles and applications in ophthalmology. It covers the basics of OCT-A, its contributions to eye disease study and treatment, and a comparative analysis with OCT for choroidal and vitreoretinal diseases. Additional information on nomenclature, normative datasets, and data analysis, presenting indices in different eye conditions is also presented. The emphasis is on macular perfusion in surgically resolved myopic foveoretinal detachment, postoperative evaluation in retinal detachment, and long-term analysis in diabetic retinopathy

This open access book provides a comprehensive overview of the application of the newest laser and microscope/ophthalmoscope technology in the field of high resolution imaging in microscopy and ophthalmology. Starting by describing High-Resolution 3D Light Microscopy with STED and RESOLFT, the book goes on to cover retinal and anterior segment imaging and image-guided treatment and also discusses the development of adaptive optics in vision science and ophthalmology. Using an interdisciplinary approach, the reader will learn about the latest developments and most up to date technology in the field and how these translate to a medical setting. High Resolution Imaging in Microscopy and Ophthalmology – New Frontiers in Biomedical Optics has been written by leading experts in the field and offers insights on engineering, biology, and medicine, thus being a valuable addition for scientists, engineers, and clinicians with technical and medical interest who would like to understand the equipment, the applications and the medical/biological background. Lastly, this book is dedicated to the memory of Dr. Gerhard Zinser, co-founder of Heidelberg Engineering GmbH, a scientist, a husband, a brother, a colleague, and a friend.

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.

This text presents a comprehensive evaluation of the recent and emerging imaging technologies for the clinical assessment of glaucoma. It should provide an understanding of the technology that is available and the results to expect from each method.

Integrated or microscope-integrated intraoperative ocular coherence tomography (i2OCT or mi-OCT, respectively) has revolutionized real-time augmentation of the surgical operating field. While corneal and retinal specialists have immediately found uses for this technology, others are beginning to use it to improve outcomes and flatten the learning curve. This book presents the use of i2OCT in pediatric ocular surgery. Case scenarios in pediatric retinal disease, corneal lamellar keratoplasty, and even pediatric cataract surgery are discussed. More novel applications highlighted include its use to identify the levator muscle in oculoplastic surgery, especially re-operations, and to assess the results of glaucoma drainage devices. Identifying extraocular muscles in re-operation for strabismus ensures minimal tissue disruption during surgery. Complex pediatric cataract surgeries can be performed far more simply and effectively using integrated ocular coherence tomography technology. This volume provides invaluable information to both early career and experienced pediatric ocular specialists, as well as any researchers who are likely to encounter i2OCT or mi-OCT technology in the future.
