This classic introduction to ophthalmology has been thoroughly revised and updated to reflect the changes in practice that have taken place since it was first published in 2009. In recent years, an increasing variety of health professionals have been involved with the care of ophthalmic patients. The aim has been to provide an efficient, high-quality and cost-effective service to patients, which utilises the skills of the multidisciplinary ophthalmic team. This study guide offers both a basic introduction and a ‘skills escalator’ for nurses and other health professionals. Those who make use of its content and use the ‘To do’ panels for reflection and research will develop their knowledge and skills more quickly, and acquire good habits of self-assessment and self-directed learning. The simple questions at the end of each chapter can be used for self-testing, or as a basis for questions that mentors can ask their students. The content is deliberately restricted to ‘the basics’ in terms of the areas chosen, though they are all covered in reasonable depth. Students are encouraged to use the skills checklists at the end of the book to document their personal progress and validate their developing practice. These will provide useful evidence for annual performance appraisals.

This book provides information on how to extract the most from mobile applications and easily adapt and integrate them into daily practice. Today mobile applications that can optimize patient flow, help in examinations, perform anterior/posterior segment imaging, offer differential diagnosis and therapeutic options and even serve as patient drug reminders and councilors are easily available. Most of them have been developed by individuals and as a result lack marketing, even though they are free to download and use. Ophthalmology has always been at the forefront of medicine when it comes to adopting the latest developments — be they lasers, off-label anti-VEGF drugs or biocompatible implants. Mobile phones and tablets have infiltrated our private and professional lives and they are here to stay. As such, this book explores the endless possibilities that mobile computing offers, and introduces the vista of opportunities for providing better care, one download at a time. As part of the series “Current Practices in Ophthalmology” this volume is intended for residents and fellows in-training, as well as general and specialist ophthalmologists.

While lecturing in recent months at a number of prominent institutions, I asked some of the residents and fellows whether and how they might benefit from a book on corneal biomechanics. The typical response was the look of a deer caught in the headlights as they tried to intuit the “appropriate” answer, but had little understanding or insight as to why this would be an important and useful knowledge base for them now, or in the future. I then posed the question differently. “Would a book that explained corneal biomechanical principles and testing devices and their application in detecting eyes at risk for developing keratoconus and post-LASIK ectasia, understanding the biomechanical impact of specific types of keratorefractive surgery and riboflavin UV-A corneal collagen cross-linking, and the impact of corneal biomechanics on the fidelity of intraocular pressure measurement and risk for glaucoma progression be of interest?” Framed in this context, the answer I got was a resounding, “Yes!” Therein lies a fundamental disconnect that highlights both the opportunity and need to educate all ophthalmologists about this nascent field. This comprehensive book is strengthened by the breadth of contributions from leading experts around the world and provides an important resource for ophthalmologists at all levels of training and experience. It gives a panoramic snapshot of our understanding of corneal biomechanics today, bridging the gap between theoretical principles, testing devices that are commercially available and in development as well as current and potential future clinical applications. While there has been a long-held appreciation that all types of keratorefractive surgery have an impact and interdependence on corneal biomechanics and wound healing, the initial finite element analyses that were applied to understand radial keratotomy were limited by incorrect assumptions that the cornea was a linear, elastic, homogenous, isotropic material.1 With the advent of excimer laser vision correction, critical observations indicated that Munnerlyn’s theoretic ablation profiles did not account for either lower or higher order (e.g. spherical aberration) refractive outcomes,2 suggesting that there were important components missing from the equation—e.g., corneal biomechanics and wound healing. In a seminal editorial, Roberts3 pointed out that the cornea is not a piece of plastic, but rather a material with viscoelastic qualities. Since that time, much has been learned about spatial and depth- related patterns of collagen orientation and interweaving, as well as the biomechanical response to different keratorefractive surgeries that sever tension-bearing lamellae, as the cornea responds to and redistributes stress induced by IOP, hydration, eye rubbing, blinking and extraocular muscle forces.3-6 The first reports of post-LASIK ectasia7 highlighted the need to identify a biomechanical signature of early keratoconus as well as corneas at high risk of developing ectasia irrespective of their current topography or tomography. The introduction of two instruments into clinical use—the Ocular Response Analyzer (ORA) and the Corneal Visualization Scheimpflug Technology (Corvis ST)—that allow measurement of various biomechanical metrics further catapulted the field. The availability of these instruments in routine clinical settings allowed the systematic study of the effect of age, collagen disorders, collagen cross-linking, corneal rings, flaps of various depths, contour, sidecut angulation, pockets, and flockets, just to name of few. Future application of biomechanics to the sclera may improve our understanding of the development and prevention of myopia, as well as scleral surgeries and treatments under development for presbyopia. It was appreciated by Goldmann and Schmidt that corneal thickness and curvature would influence the measurement of applanation tonometry. The recent ability to measure some corneal biomechanical metrics have led to IOP measurement that may be more immune both to their influence and the impact of central corneal thickness (CCT). Certain chapters in this book explain how a thin cornea could be stiffer than a thick one and that stiffness is also impacted by IOP, thereby precluding simplistic attempts to adjust IOP measurements using nomograms based upon CCT alone. Also highlighted is how corneal hysteresis, the ability of the cornea to absorb and dissipate energy during the bidirectional applanation response to a linear Gaussian air puff, appears to be an independent risk factor for glaucoma progression and rate of progression.9,10 This comprehensive book starts out with a section devoted to outlining basic biomechanical principles and theories, teaching us the language of what Dupps11 has referred to as “mechanospeak”, thus providing a context and common vocabulary to better comprehend the following chapters. By first defining basic concepts such as stress-strain relationships and creep, this theoretical basis is later applied to explain the pathogenesis of corneal diseases, e.g., explaining how a focal abnormality in corneal biomechanical properties precipitates a cycle of decompensation and localized thinning and steepening, clinically expressed as ectasia progression. These early chapters further detail biomechanical differences between in-vivo and ex-vivo testing, between human and animal corneas and sclera, and between methods of testing. The second section provides a thorough description of two FDA-approved devices to measure corneal biomechanics in the clinic (i.e., the ORA and the Corvis ST), as well as an overview of potential future technologies, including OCT with air puff stimulus, ocular pulse elastography, and Brilloiun microscopy. The third and final section of the book is a thorough treatise on how to interpret the metrics derived from the waveform provided by available clinical devices; their adjunct use in ectasia risk screening; the comparative biomechanical impact of various keratorefractive surgeries and corneal procedures such as PRK, LASIK, SMILE, and corneal collagen cross-linking; the impact of corneal biomechanics on IOP measurement; and potential biomechanical markers of enhanced susceptibility to glaucoma progression. This compendium of our current knowledge of corneal biomechanics, its measurement and application, provides a strong foundation to more fully understand advances in keratorefractive and corneal surgery, diseases, and treatments, all of which are interdependent on and influence inherent corneal biomechanical properties and behavior. Both the robust aspects and limitations of our current understanding are presented, including the challenge of creating accurate and predictive finite element models that incorporate the impact of IOP, corneal thickness, geometry, and scleral properties on corneal biomechanics. This book provides a key allowing clinical ophthalmologists and researchers to grasp the basics and nuances of this exciting field and to shape it as it evolves in the future.

Fifty million Americans suffer from allergies to certain foods, pollens, animal danders, dust mites and other less common allergens. Although the most common symptoms, from watery eyes to hives, are not life-threatening, there is a substantial cost in health care spending associated with these conditions. Americans spent about $18 billion each year on asthma care in 2009. And of the $19 billion spent each year on over-the-counter remedies, a substantial portion is spent on allergy medications. Now two specialists in allergy medicine reveal how to manage allergies safely and effectively, and live more comfortable, symptom-free lives. Allergies debunks the many myths about allergies and offers long-term help to both seasonal and chronic sufferers. This comprehensive and authoritative resource helps you make informed choices about everything from diagnostic tests to nasal antihistamines and corticosteroid sprays, from homeopathic remedies for poison ivy and insect bites to desensitizing therapies and emergency relief for severe allergic reactions and much more, including: • A detailed evaluation of the most common over-the-counter drugs • How to minimize allergens like mites, pollen and danders in your house. • Useful advice for life threatening allergies such as food and stinging insects. • Allergies and exercise • Allergies and pregnancy • Skin disorders from allergies • When allergy shots are unnecessary • Self-treatment versus traditional care • How to recognize and avoid allergy scam treatments • Allergies in children and the elderly • Plus a comprehensive guide to reliable information on the internet
