Vital Dyes in Vitreoretinal Surgery


Book Description

Chromovitrectomy is a novel approach to visualize the vitreous or retinal surface during vitreoretinal surgery. In recent years, the widely used indocyanine green (ICG) has made the surgical maneuver of inner limiting membrane peeling tremendously safer and efficient. Also, numerous dyes have been applied in experimental settings with promising or devastating results. This volume highlights the major clinical and experimental results of currently used novel vital dyes. The first chapters describe the transparent structure of the vitreous body and summarize historical considerations to visualize its structure by optical coherence tomography, dye injections or autologous cells during surgery and for diagnostic purposes. The following contributions describe the advantages and disadvantages of ICG during vitreoretinal surgery and experimental applications. Alternative approaches by recently approved vital dyes such as trypan blue, patent blue and brilliant blue are evaluated in the subsequent chapters. Finally the last few chapters give an outlook on novel vital dyes, which are currently under evaluation, as well as alternative enzymatic approaches to remove the vitreous from the retinal surface. Being a timely update this publication will be indispensable reading for vitreoretinal surgeons and ophthalmic researchers.




Retinal Pharmacotherapeutics


Book Description

The use of pharmacotherapeutics in the management of retinal diseases is rapidly evolving, and a favorable therapy for the patient. Today anti-VEGF agents are used for a range of indications from inflammation-related choroidal neovascularization to macular edema secondary to retinal vein occlusion or diabetic retinopathy. Beyond VEGF, there is an array of target areas under investigation – not only for vascular pathologies such as age-related macular degeneration and diabetic eye disease, but also for degenerative, infectious and inflammatory retinal conditions. This publication discusses many aspects from basic research on the retina, to animal models for retinal drug delivery, retinal diseases that are amenable to pharmacotherapy and also drugs and mechanisms in retinal diseases. Anyone concerned with the management of retinal diseases - the general ophthalmologist and the retina specialist alike – will find this book indispensable reading.




Microincision Vitrectomy Surgery


Book Description

Over the last two decades, tremendous progress has been made in vitrectomy surgery, most importantly the significant reduction of the gauge and implementation of microincision vitrectomy surgery (MIVS). At the same time, the introduction of wide-viewing systems and the utilization of vital dyes to better recognize structures like the vitreous and membranes have taken place. This volume starts with the fundamentals of MIVS, introducing both the mechanics and the physics of the latest generation of vitrectomy devices, followed by a description of the discrete gauge systems (i.e. 23-, 25-, and 27-gauge). Individualized but mandatory settings, techniques, and technology are also discussed in detail. There are also more than ten chapters outlining concrete surgical strategies that give surgeons a thorough overview of the procedures.




Vitreoretinal Disease


Book Description

The management of major vitreoretinal diseases has changed dramatically since publication of the first edition in 1999. The field continues to evolve rapidly and is becoming an increasingly complex, multifaceted practice of medicine and surgery. As such, retinal specialists are faced with increasingly sophisticated diagnostic and therapeutic modalities to learn and master. Contributors to this completely updated reference are renowned experts in retinal disease and vitreous disorders. Divided into four essential sections, the book starts with a basic overview of posterior segment anatomy and physiology. The second section reviews the spectrum of diagnostic tools used in the field from relatively low technology such as the indirect ophthalmoscope to the latest, state-of-the-art optical coherence tomography test. The third and most comprehensive section covers disease states, subdivided into eight categories: retinovascular conditions, macular diseases, inherited vitreoretinal conditions, inflammatory conditions, intraocular tumors, vitreous and retinal detachments, trauma and toxicity, and fundus conditions. The text concludes with specific vitreoretinal procedures. Key Features New technologies including spectral domain optical coherence tomography (OCT), intravitreal injections, and microincisional vitrectomy The utilization of multifocal electroretinography, scanning laser ophthalmoscopy, and fundus autofluorescence Advances in treatment of macular edema and age-related macular degeneration with anti-VEGF therapy Summaries of the latest and most important clinical trials Richly illustrated with more than 700 color state-of-the art retinal images and surgical procedure drawings Clinical pearls, controversies, and special considerations highlighted in color boxes in every chapter This up-to-date, clinically-oriented resource will greatly benefit ophthalmology residents and ophthalmologists with comprehensive practices.

Macular Surgery


Book Description

Recent technological advances in the diagnosis of macular disorders have enhanced our understanding of these diseases. At the same time, advances in small-gauge vitrectomy instrumentation and techniques have improved the safety and efficiency of surgery, allowing macular conditions that would have otherwise resulted in blindness to be treated effectively, preserving patients’ sight. Macular surgery continues to evolve rapidly, thanks to exciting future technology trends. This book provides a detailed and up-to-date overview of the field. It begins with essential information on macular anatomy and pathophysiology, examination techniques, and surgical instrumentation. In turn, it discusses a broad range of disease processes, including macular holes, epiretinal membrane, vitreomacular traction and myopic maculopathy. The role and benefits of advanced vitrectomy techniques including submacular surgery, prosthetic vision, robotic surgery, and stem cell and gene therapy are addressed in detail. A review of perioperative care and potential complications rounds out the coverage.




Vitreoretinal Surgery


Book Description

This is the second edition of a highly successful textbook that in many areas has become the preferred manual of vitreoretinal surgery. It provides a complete guide to all common vitreoretinal surgical procedures and also covers diagnosis and other aspects of management. The book is designed to allow a trainee or professional vitreoretinal surgeon to determine the best methodology in individual cases. In order to acquaint the reader with different opinions, “surgical pearls” have been contributed by other international experts in the field. These have proved popular in the past as an illustration of alternative methods, without detracting from the overall method described by the main author. Vitreoretinal Surgery will continue to prove particularly popular amongst trainees, but will also be of value to practicing professionals who need help in the management of difficult and rare cases. The text is backed up by the provision of videos of some aspects of the surgery.




Challenges in Sun Protection


Book Description

In the early 20th century, tanned skin was associated with good health. However, people began to protect themselves against potential overexposure to avoid sunburns. Around 1945, the first sunscreen products became available. In the years to follow, a vast number of different sunscreen filters and frameworks regulating filter substances and preparations, and methods characterizing sunscreen products were developed. The perception regarding the tasks of sunscreen products changed several times – initially it was promoted as a lifestyle product, then as a skin cancer preventive means, and more recently also for anti-aging. Different purposes and the widespread use of these products have led to myriad studies and a wealth of information. In this volume, the editors present a current collection of information analyzing and discussing issues related to sunscreen products and their use. These include challenges regarding the ideal sunscreen product including filter selection and formulation issues, measurement methods, performance characterization, safety, and regulatory issues. Further papers address topics related to the use of sunscreen products in everyday life, in vulnerable cohorts and outdoor workers. Controversial topics such as environmental effects of sunscreen products and the risks and benefits of UV radiation in the context of skin cancer, vitamin D and cardiovascular and metabolic health are also covered.
