Download and read online The Ophthalmic Study Guide in PDF and EPUB 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.
Download and read online Corneal Biomechanics in PDF and EPUB 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.

Download and read online Die Geheimnisse des Nicholas Flamel Der unsterbliche Alchemyst in PDF and EPUB Ein geheimnisvolles Buch, ein unerkannter Magier, ein abenteuerlicher Wettlauf gegen die Zeit San Francisco 2007. Am helllichten Tag, in Nick Flemings Buchhandlung, trauen Sophie und Josh kaum ihren Augen: Ein Unbekannter attackiert den Buchladenbesitzer Fleming mit purer Magie – und entkommt mit einem alten Buch. Was die Zwillinge nun erfahren, ist unfassbar: Nick Fleming ist kein Geringerer als der berühmte Alchemyst Nicholas Flamel, geboren vor über 670 Jahren. In einem alten Zauberbuch, dem legendären Codex, entdeckte er das Geheimnis ewigen Lebens. Und genau dieses Buch hat der Fremde gestohlen. Die Mächte des Bösen versuchen schon seit Jahrhunderten, den Codex in ihre Gewalt zu bringen – denn mit ihm allein könnten sie die Herrschaft über die Welt zurückgewinnen. Nicholas Flamel, Josh und Sophie haben genau einen Monat Zeit, um das Zauberbuch zurückzuholen. Ein atemberaubender Wettlauf gegen die Zeit beginnt! • Der fulminante Auftakt der packenden Fantasy-Saga • Rasant wie ein Kinofilm und unglaublich spannend • Nicholas Flamel: bekannt aus „Harry Potter“ und „Sakrileg“ Leserstimmen vom cbj-Leseclub: Ich habe soeben den Roman "Der Alchemyst" ausgelesen und muss ehrlich sagen, dass ich ziemlich begeistert bin. Es sind im Wesentlichen zwei Aspekte, die das Buch so besonders und so faszinierend machen: zum Einen kreiert die Auswahl an unterschiedlichen Perspektiven ein nahezu einzigartiges Spannungsmoment. Michael Scott schafft es auf beeindruckende Weise, einzelne Szenen wiederholt so aus verschiedenen Blickwinkeln zu erzählen, dass der Leser einen ganz anderen Ein- und Überblick auf das Geschehen bekommt. (...)Der zweite Aspekt, der Michael Scotts Roman für mich so lesenswert gemacht hat, ist die Tatsache, dass er in dieser einen Geschichte ein Vielzahl von Mythen, Sagen, Legenden und historische Fakten so miteinander verknüpft, dass tatsächlich ein übergeordnetes Muster entsteht und alles einen Sinn macht.Isabel (17) Ich glaube dieses Buch würde meine Altersgenossen interessieren, denn diese Kinder sind genau wie wir am Anfang: technikverwöhnt und ein bisschen überheblich. Als es dann ans Zaubern geht, ist es gänzlich um die Jugendlichen geschehen. Denn wer hat sich noch nicht gewünscht aus Metall Gold zu machen oder mit Energiekugeln durch die Luft zu werfen. Mich selbst hat das Buch gleich von Anfang an in den Bann gezogen.Das Buch beginnt mit einem Knall, beruhigt sich wieder und endet mit einer Explosion. Es ist so aufgebaut das dem Leser nie langweilig wird. Viele Überraschungen und tolle Kämpfe sind die ganze Zeit vorhanden. Die Idee ist also optimal umgesetzt.Auch durch die sprachliche Gestaltung hat man das Gefühl live dabei zu seinCarolin (14)
