This unique book is a comprehensive coverage of the epidemiology of the world's major blinding eye diseases, written by internationally acclaimed experts in each field. Edited by world-renowned epidemiologists and ophthalmologists, the chapters on each leading cause of blindness describe its biology, epidemiology, risk factors, clinical trials, possibilities for prevention, and new research avenues. New chapters include Research Synthesis, Epidemiology of Dry Eye Disease, and Epidemiology of Uveitis, as well as programme issues for reaching the goal of eliminating avoidable blindness by 2020.This book is essential for any eye care practitioner interested in the causation or prevention of disease, and should be part of any public health discipline's library with a focus on improving eye health worldwide.
When the eyeball is indented in total darkness, within less than 200 mil liseconds an oval or quarter-moon shaped spot of light is perceived in the part of the visual field corresponding to the indented region of the retina. In the seconds following, this phosphene extends across the whole visual field and alters in structure during further eyeball indentation. It is then seen as irregular large bright spots of light, finely structured moving light grains ('light nebula') and stationary bright stars. Regular geometrical patterns appear only when both eyes are indented simultaneously [1]. When the eyeball deformation is released, part of the retina again lights up for another one or two secon...

The book offers a novel and original synthesis of work in modern political theory and in political science and political economy to offer a theory of democratic justice, considering society as a social contract.
At the end of the Second World War, nearly 200 British citizens were under investigation for assisting Nazi Germany. Some have remained notorious, such as William Joyce (Lord Haw-Haw) and John Amery who went to the gallows for High Treason, but as this meticulously researched study shows, men like Joyce and Amery are only the visible part of a much larger and more intriguing story below the surface. Renegades is drawn entirely from original documentary material, eyewitness accounts and intelligence files. Adrian Weale traces the course of treason in the Second World War from its roots in Oswald Mosley's British Union of Fascists, through the war and subsequent investigations by MI5, up to th...
Provides the fundamentals, technologies, and best practices in designing, constructing and managing mission critical, energy efficient data centers Organizations in need of high-speed connectivity and nonstop systems operations depend upon data centers for a range of deployment solutions. A data center is a facility used to house computer systems and associated components, such as telecommunications and storage systems. It generally includes multiple power sources, redundant data communications connections, environmental controls (e.g., air conditioning, fire suppression) and security devices. With contributions from an international list of experts, The Data Center Handbook instructs reader...
Ophthalmic epidemiology is the subject of international research: common ophthalmic conditions in industrialized countries receiving attention as well as the main blinding diseases of the developing nations. For those public health officials, health planners and ophthalmologists responsible for developing programmes aimed at the prevention of blindness, this book provides a one-stop source of relevant information derived from major epidemiological studies on prevalence, risk-factors and distribution of eye disease. Internationally applicable, the methodology used in developing countries will prove valuable in developed nations where economic growth and rising affluence have created similar conditions.
