The blinding diseases of inherited retinal degenerations have no treatments, and age-related macular degeneration has no cures, despite the fact that it is an epidemic among the elderly, with 1 in 3-4 affected by the age of 70. The RD Symposium will focus on the exciting new developments aimed at understanding these diseases and providing therapies for them. Since most major scientists in the field of retinal degenerations attend the biennial RD Symposia, they are known by most as the "best" and "most important" meetings in the field. The volume will present representative state-of-the-art research in almost all areas of retinal degenerations, ranging from cytopathologic, physiologic, diagnostic and clinical aspects; animal models; mechanisms of cell death; candidate genes, cloning, mapping and other aspects of molecular genetics; and developing potential therapeutic measures such as gene therapy and neuroprotective agents for potential pharmaceutical therapy. While advances in these areas of retinal degenerations will be described, there will be many new topics that either were in their infancy or did not exist at the time of the last RD Symposium, RD2014. These include the role of inflammation and immunity, as well as other basic mechanisms, in age-related macular degeneration, several new aspects of gene therapy, and revolutionary new imaging and functional testing that will have a huge impact on the diagnosis and following the course of retinal degenerations, as well as to provide new quantitative endpoints for clinical trials. The retina is an approachable part of the central nervous system (CNS), and there is a major interest in neuroprotective and gene therapy for CNS diseases and neurodegenerations, in general. It should be noted that with successful and exciting initial clinical trials in neuroprotective and gene therapy, including the restoration of sight in blind children, the retinal degeneration therapies are leading the way towards new therapeutic measures for neurodegenerations of the CNS. Many of the successes recently reported in these areas of retinal degeneration sprang from collaborations established at previous RD Symposia, and many of those will be reported at the RD2018 meeting and included in the proposed volume. We anticipate the excitement of those working in the field and those afflicted with retinal degenerations will be reflected in the volume.

The editors have set out to provide the reader with a diversity of interesting topics reflective of the evidence-based, modern approach to the field of glaucoma. Written for: Ophthalmologists in clinical and private practice, residents, ophthalmologists-in-training as well as optometrists and ophthalmic nurses

Studies on Retinal and Choroidal Disorders examines the role that oxidative and nitrosative stress plays in the complex physiology and pathophysiology of the retina and choroid. Both the basic science researcher and the clinical practitioner can use this book as a guide to the current understanding of retinal and choroidal cellular mechanisms involved in aging and disease. Beginning with a review of oxidative stress and inflammation in the pathoetiology of AMD and a review of the complement system in the retina, the book then takes a detailed look at oxidative stress in lipid metabolism and oxidized lipoproteins in the retina. It examines the anti-apoptotic activity of -crystallins in the presence of glutathione, oxidative stress in the mitochondria and endoplasmic reticulum, the role of iron in retinal disease, the mechanisms of pathological VEGF expression, NAPDH oxidase mechanisms, and Hepatocyte Growth Factor in oxidative stress in the retina. A detailed look at the Ccl2-/-/Cx3cr1-/- mouse model of AMD follows. Then a detailed examination of the systemic changes in AMD is followed by a discussion of cerium oxide nanoparticle reduction of oxidative stress. Two chapters discuss progenitor cells in the cause and treatment of retinal diseases including AMD and diabetic retinopathy. Natural compounds in the prevention and treatment of retinal diseases are exhaustively presented, followed by a chapter on serotonin 5-HT1A receptor agonists in oxidative stress of the retina. The current anti-VEGF treatment strategies of neovascular AMD are then given. The volume continues with a detailed look at nitric oxide and inducible nitric oxide synthase in retinal vascular disease, an explanation of an in vivo technique of studying the effect of lipid hydroperoxides on circulating leucocytes in the retina, an excellent review of oxidative stress in retinopathy of prematurity, and a look at VEGF induced oxidative stress in the retinal ganglion cell. The book ends with a detail examination of the role of carotenoids in retinal health and disease. These 31 chapters summarize what is known about oxidative stress in retinal and choroidal disorders. All those involved with degenerative diseases of the eye will find Studies on Retinal and Choroidal Disorders to be illuminating and comprehensive.

This book covers a wide range of topics concerning human tear based science, starting from basics such as the normal composition of tears and moving up to novel disease detection platforms. The entire approach is pioneering, as tears are beginning to be recognized as the most invaluable non-invasive tool in diagnostics. Interestingly, the concept is not restricted to ocular diseases: In recent years, tear diagnostics is increasingly being tapped even for cancer detection. Hopefully, non-invasive tear diagnostics will eventually replace today's invasive disease detection and monitoring techniques. Previous literature on tear diagnostics has been restricted to scientific journal articles, most of which dealt with a single tear constituent, such as a protein. This book offers a far more comprehensive and handy 'reference guide,' presenting both basic and advanced information and data. Accordingly, it will be useful for researchers in academia and the pharmaceutical industry, as well as healthcare professionals and diagnostic kit developers.

It highlights recent technological innovations and new treatments that have significantly improved the ability to accurately evaluate and successfully treat these lesions with reduced complications. Some of these advances include new imaging modalities, intravascular and intralesional treatment approaches, photodynamic therapy, and additional medical therapies. Many of these advances have led to paradigm shifts in the understanding and management of vascular lesions of the orbit and face. This book, written by experts in the fields of ophthalmology, dermatology, diagnostic and interventional radiology, and oculoplastic surgery, features structured, in-depth chapters that can also be quickly consulted as a reference guide. It is an excellent resource for those in training as well as seasoned practitioners wishing to acquaint themselves with the newest diagnostic and treatment techniques for orbital vascular lesions.

Prolonged microgravity exposure during long-duration spaceflight (LDSF) produces unusual physiologic and pathologic neuro-ophthalmic findings in astronauts. These microgravity-associated findings collectively define the Spaceflight Associated Neuro-ocular Syndrome (SANS). In this book, the editors compare and contrast prior published work on SANS by the National Aeronautics and Space Administration's (NASA) Space Medicine Operations Division with retrospective and prospective studies from other research groups. The book describes the possible mechanisms and potential etiologies for SANS, and provides an update and review on the clinical manifestations of SANS including: unilateral and bilateral optic disc edema, globe flattening, choroidal and retinal folds, hyperopic refractive error shifts, and focal areas of ischemic retina (i.e., cotton wool spots). The ocular imaging findings (e.g., retinal nerve fiber layer, optic disc, and choroidal changes on optical coherence tomography) of SANS is also described, including the intraorbital and intracranial findings on orbital ultrasound and magnetic resonance imaging. The knowledge gaps for in-flight and terrestrial human research including potential countermeasures for future stud is also explored, including reports on the in-flight and terrestrial human and animal research being investigated by NASA and its partners to study SANS both prospectively and longitudinally and in preparation for future long duration manned missions to space including the moon, the asteroid belt, or Mars. We think this is a unique topic and hope that NASA and its research partners continue to study SANS in preparation for future longer duration manned space missions.

As a degenerative disorder of the eye, keratoconus can cause substantial distortion of vision, with multiple images, streaking, and sensitivity to light all reported by patients. Keratoconus: Recent Advances in Diagnosis and Treatment updates ophthalmologists about the innovations that have occurred within the last decade, discussing the diagnostic imaging techniques that have been developed for keratoconus diagnosis, understanding of how examination techniques are related to the evolution of keratoconus, and how to indicate the different therapeutic tools that have been created for keratoconus over the last several years. Additionally, fundamentals for new diagnostic elements, based on the mathematical, physical and biomechanical data are analyzed in depth for a better understanding of the essential diagnostic steps for the clinician to guide patients towards the most adequate therapeutic tool in the case. Modern keratoplasty techniques, assisted by femtosecond lasers or other devices, are also covered and these techniques, along with the emerging conservative treatments, have added to more precise control of the evolution of the disease.

Confocal microscopy with laser scanning technology yields in-vivo images of ocular and ocular adnexal surfaces that are so brilliant that they rival histology in terms of quality.This unique atlas and textbook demonstrates normal in-vivo anatomy of the cornea, limbus and conjunctiva, quantifies various cellular structures using cell-density calculations and establishes correlations between novel optical sections of various diseases of the ocular surface and clinical findings. Furthermore, it supports the interpretation of novel high-magnification optical sections by comparing corneal and conjunctival imprint cytology with in-vivo images and describes early inflammatory changes in corneal grafts, as well as corneal conjunctivalisation in limbal stem cell deficiency, corneal dystrophies or infections, flap interface and margin characteristics after laser in-situ keratomileusis (LASIK). In addition, it instructs the reader about diagnostic and therapeutic follow-up strategies and provides a brief introduction to applications in other fields such as dentistry and ear, nose and throat surgery.

The desire to teach and the fulfillment attained from teaching have again prompted us to produce a work that we hope is both useful and enlightening to our readers. The field of oculoplastic surgery has grown and evolved to include all aspects of eyelid and facial plastic surgery. Our literature must now reflect the advancements and - rection of our field. Knowledge of anatomy, the basis of all surgery and the root of surgical principles and techniques, supports our ab- ity to deliver the highest quality care to our patients. We have therefore combined text and diagrams and supplemented them with DVD digital video technology to enable those who wish to perform this surgery the best possible instruction and preparation. We hope that our attempts to accomplish this will be rewarded by the use of this material by colleagues and the acknowledgment of our unique and logical progression in the field of eyelid and facial pl- tic surgery. The previous volume in this series covered reconstructive eyelid surgery. This volume presents many aspects of facial cosmetic surgery, including blepharoplasty, endoscopic forehead surgery, rhytidectomy, and other related procedures. Future volumes will pr- ent facets of lacrimal and orbital surgery. Frank A. Nesi, MD vii ACKNOWLEDGMENTS Bringing a book project to fruition is always a complicated process involving many people. It is through their dedication, profession- ism, and team effort that it all comes together.

Over the weekend of 21-23 February 1997, a small group gathered in Tallahassee, Florida, at the invitation of Ted Williams, to discuss "photo stasis and related topics." The majority of participants were former students and colleagues of Ted's, but an occasional outsider such as myself was generously included. The papers presented there are collected in this volume. The theory of photo stasis was first outlined in a landmark paper by John Penn and Ted, published in 1986 in Experimental Eye Research. They provided compelling data showing that, in the albino rat eye, levels of rhodopsin, outer-segment length, rhodopsin regeneration rate, and even, perhaps, rhodopsin packing density all depend on the levels of cyclic illumination (12 hours light, 12 hours dark) in which the animal was reared. So, for example, there is fourfold less rhodopsin in a retinal extract derived from an animal reared at 400 lux than in an extract from the retina of an animal reared at 3 lux. Animals reared at intermediate levels of light show intermediate amounts of rhodopsin that are correlated with illumination level. What these data immediately suggested is that the photoreceptor cell can adjust its photon-catching ability in response to the levels of light in which an animal is reared, and they also provided a compelling rationale for outer-segment turnover, a phenomenon discovered 20 years earlier by Richard Young but whose function has remained obscure.
