Abnormal or deficient capsular anatomy creates numerous surgical challenges and predisposes eyes to IOL complications. Literally dozens of different approaches have been devised to implant IOLs in the face of compromised capsular support. However, a comprehensive compendium of the most important surgical strategies has not existed, until now. Advanced IOL Fixation Techniques: Strategies for Compromised or Missing Capsular Support provides this much-needed resource with more than 70 different chapters that cover the wide array of surgical approaches. Among the contributors are many of the original innovators of the most important technologies and methodologies. In addition to teaching a specific surgical technique, these authors cover its history, rationale, and clinical results. Editor Dr. David F. Chang is well known and acclaimed for 2 best-selling cataract textbooks-Mastering Refractive IOLs and Phaco Chop and Advanced Phaco Techniques. Along with associate editors Drs. Bryan S. Lee and Amar Agarwal, Dr. Chang has now tackled this new major subject area-how to best fixate IOLs when capsular support is compromised or absent. Part One covers capsular fixation with either zonulopathy or following posterior capsule rupture. Topics include using conventional and modified capsular tension rings, capsular tension segments or capsular anchors, standard and reverse optic capture with anterior capsulorrhexis, sulcus fixation, posterior capsulorrhexis, and capsular membrane suture fixation. Part Two covers noncapsular fixation. Topics include anterior chamber IOLs, iris claw IOLs, iris and transscleral suture fixation of posterior chamber IOLs, and intrascleral haptic fixation using the Yamane double-needle or glued IOL methods. Part Three covers miscellaneous topics such as anterior vitrectomy, IOL power calculation for noncapsular IOLs, and sliding slip knots and suture pupilloplasty. To facilitate skills transfer, most chapters present detailed, step-by-step descriptions of the different techniques. The maneuvers are illustrated by over 1,100 diagrams and high-resolution surgical images. Finally, nearly every chapter is accompanied by narrated instructional videos. Combining over 150 videos, schematic diagrams, surgical images, and detailed written descriptions, Advanced IOL Fixation Techniques provides the most effective way to learn advanced surgical techniques. With its comprehensive and practical approach to covering the gamut of strategies and devices, Advanced IOL Fixation Techniques: Strategies for Compromised or Missing Capsular Support will be an indispensable resource for cataract surgeons at all levels of experience.

Optical Coherence Tomography Angiography (OCTA) is a novel, non-invasive, dyeless imaging modality that has emerged as an indispensable tool in the fields of optometry and ophthalmology.  OCTA provides three-dimensional volumetric images of the retinal and choroidal vasculature by using a motion-contrast decorrelation algorithm.  This cutting-edge imaging technology has widespread clinical utility as a non-invasive alternative for visualizing microvasculature in detail, but there are no textbooks dedicated to its use and the interpretation of scans. To fill this need, Optical Coherence Tomography Angiography Atlas: A Case Study Approach, by Dr. Julie A. Rodman, is a richly illustrated, practical guide to OCTA. It provides detailed information on the fundamental principles behind the technology, as well as clinical applications critical for accurate interpretation. The first section of the book discusses the principles behind OCTA and provides an introduction into the interpretation of OCTA images, including a chapter devoted to terminology. The remainder of the book provides detailed analysis of a myriad of inner and outer retinal disorders, including diseases of the optic nerve head. Most importantly for the clinical setting, the cases are presented with numerous images and a multitude of arrows and callouts to assist in the recognition of various clinical findings. Case examples include: Vascular Occlusive Disease Pigment Epithelial Detachment Choroidal Neovascular Membrane Diabetic Retinopathy Optic Disc Edema Dr. Rodman's emphasis on the clinical use of OCTA technology and step-by-step interpretation of images makes Optical Coherence Tomography Angiography Atlas: A Case Study Approach a must-have resource for physicians, residents, students, and ophthalmic technicians looking for a simple, comprehensive guide to OCTA.

Just as neuro-ophthalmology links ophthalmology with other medical specialties, so too the optic nerve links the eye with the central nervous system. Thus, ophthalmologists must be familiar with a wide variety of optic nerve diseases, which may occur in isolation or form part of a generalised neurologic or systemic disorder. Optic Nerve Disorders is an up-to-date guide to the relevant literature on a wide variety of clinical diseases of the optic nerve that will give the clinician a handy reference to assist in both their diagnosis and management. It provides a succinct, yet comprehensive review of optic nerve disorders commonly encountered in clinical practice, briefly reviews the anatomy and physiology of the optic nerve, and outlines those techniques of particular importance during clinical testing of optic nerve function. Chapter 1 reviews the major anatomic aspects of the optic nerve at both a macroscopic and a microscopic level, and discusses the critical role of axonal transport in optic nerve physiology. Chapter 2 takes the reader back to basics, emphasising the importance of obtaining a detailed patient history and performing a careful ophthalmologic examination. Chapters 3 through 9 cover the major clinical disorders affecting the optic nerve: papilledema, optic neuritis, ischemic optic neuropathy, compression of the anterior visual pathways, developmental and hereditary optic nerve disorders, toxic and nutritional optic neuropathy, and traumatic optic neuropathy. The last chapter, Chapter 10, summarises those optic neuropathies that cannot easily be categorised, but that frequently confront the general ophthalmologist in clinical practice.

On 22 November 2003, the House of Representatives voted 220 to 215 to approve the conference report on H.R. 1, the Medicare Prescription Drug, Improvement, and Modernisation Act of 2003. The Senate, on November 24th, voted 54 to 44 to approve the conference report. The bill was signed by the President in a ceremony on December 8th. The legislation adds a prescription drug benefit to Medicare and replaces the existing Medicare+Choice program with a new Medicare Advantage program that establishes managed care payments based on a system of bids and benchmarks. The bill also contains numerous provisions that would generally increase fee-for-service payments within Medicare's Part A and Part B program (also known as traditional Medicare), especially for rural health care providers; numerous regulatory and administrative practices will also be modified. This book discusses the fee-for-service (FFS) provisions of the legislation, those affecting Medicaid as well as the Medicare cost containment provisions. It compares the provisions in the bill as enacted with those in the Medicare reform bills that were originally passed by the Senate and the House. through VIII; some FFS provisions are included in Titles VIII through X as noted. The cost containment provisions are in Title VIII and the Medicaid and other provisions are in Title X. CONTENTS: Preface; Introduction; Changes to Medicare's Fee for Service Program; Index.

Retinal dystrophies are the major causes of incurable blindness in the Western world. Our insight into their aetiology has improved remarkably over the past decade and a number of key genes have been identified. Together with a more detailed understanding of disease processes, this knowledge is stimulating new approaches to therapeutic strategies involving gene therapy, growth factors and retinal cell transplantation.

Molecular genetic studies have provided detailed information on the pathogenesis of retinal dystrophies. An important proof of principle that gene therapy holds great promise for the treatment of these conditions was demonstrated in the "rds" mouse: introduction of a functional copy of the "peripherin" gene subretinally resulted in complete rescue of rod outer segment structure. Novel approaches are being developed based on the manipulation of biochemical pathways that previously were not considered relevant to these diseases. For example, renewed interest in retinal dystrophy pathogenesis led to the successful use of high dose vitamin A treatment in Sorsby fundus dystrophy.

This important new book covers all aspects of retinal dystrophies from the molecular and developmental biology of these disorders to possible therapeutic approaches, with special reference to gene therapy. Specific chapters deal with the molecular genetics of gene therapies, clinical genetic studies, molecular and cellular mechanisms of the development of the disease, functional genomics of retinal diseases, animal models of retinal dystrophies, and finally with studies on gene therapeutic approaches to correcting the disorder. With contributions by many of the leading researchers worldwide, this book is likely to be an important milestone in this rapidly developing field.

The Neuropsychology of Vision describes a range of new approaches to neuropsychological investigation and provides a broad overview of visual neuropsychology. The book starts by presenting the results from new research employing single-unit recordings, on the neuronal basis of perception demonstrating that the visual system relies strongly on feedback from higher to lower levels of information processing, and that neuronal plasticity exists in the primary sensory cortices of adults, areas previously considered to be hard-wired. The book also describes other new and adapted techniques to measure brain activity, including multi-unit sum potential recording, functional magnetic resonance imaging and employing transcranial magnetic stimulation to induce temporary, circumscribed functional lesions in the cortices of normal subjects to mimic disorders.

The coverage then moves on to review the experience of patients suffering from disturbances of visual perception. The disorders covered include agnosia, neglect, blindsight and achromatopsia. The final chapter is devoted to recovery and rehabilitation from cerebral visual disorder.

The surgical correction of astigmatism is the last frontier to optimizing visual outcomes for patients. Practical Astigmatism: Planning and Analysis is a comprehensive guide to correcting astigmatism from pre-operative planning to post-operative analysis. This provides readers with unique insight to what actually happened surgically: did the astigmatism over or under correct? Was it on-axis or off-axis? With this book, ophthalmologists will be able to analyze previous procedures with the appropriate nomograms and more often achieve targeted outcomes. Dr. Noel Alpins has developed the Alpins Method of astigmatism to provide accurate planning and analysis of astigmatism procedures. His method focuses on analyzing refractive and corneal astigmatism parameters and using the results in future surgery to improve visual outcomes. The importance of the ocular residual astigmatism (ORA) is detailed when planning astigmatism surgery. Practical Astigmatism features vector planning for refractive laser surgery as well as planning and analysis applied to cataract and limbal relaxing incisions, , in addition to demonstrating graphical analysis of astigmatism using high quality vector and fan diagrams, as used in scientific journals. In addition, hemidivisional analysis of the irregular cornea, corneal coupling in incisional and excimer laser surgery for mixed astigmatism and toric IOL planning with total corneal power using corneal topographic astigmatism (CorT total) are addressed as well. Some Questions Answered Inside: What is the difference between regular and irregular astigmatism? How do I diagnose each, and how does this affect my surgical technique? Can I incorporate corneal astigmatism when performing excimer laser surgery? Why are my LRIs undercorrecting the astigmatism? Is it safe to perform excimer laser on keratoconous patients? Which corneal astigmatism measure do I choose and what do I do following a refractive surprise? Practical Astigmatism: Planning and Analysis will help ophthalmologists, optometrists, and technicians alike address each patient’s unique circumstances and act as your in-depth guide to correcting astigmatism.   Testimonials… “For more than three decades I have been listening to, arguing with, and admiring the work of Dr. Noel Alpins in the field of astigmatism.  Despite his remote location on the small island of Australia, his knowledge of astigmatism is at the peak of Mt. Everest.  There are few others who have devoted their careers to understanding and managing astigmatism for which the world of ophthalmology is truly grateful.�  - Robert H. Osher, MD “Noel is an original thinker who took on and conquered the complexities of astigmatism analysis, publishing the seminal papers on the way. His work has formed the cornerstone from which our current understanding and management of astigmatism has been built. He is someone from whom we have all learnt a great deal and this book is a testament to this.� - Dan Z Reinstein, MD MA(Cantab) FRCSC DABO FRCOphth FEBO
