Emergency ophthalmology is an area full of pitfalls for the unwary primary care practitioner. Vitreoretinal disorders make up the majority of emergency sight-threatening conditions, and a wide and increasingly varied range of conditions of the eye present in primary care settings. Correct diagnosis at initial presentation, and appropriate and speedy referral, are extremely important. This book is therefore an essential reference for the primary care physician, who is often the first to see these patients and is in a position of responsibility for decision-making.

"Molecular Genetics of Inherited Eye Disorders" provides an authoritative and up-to-date account of molecular genetic advances in a wide spectrum of genetic eye disorders, and forms the second volume in the Modern Genetics book series. The field has produced some dramatic and often unexpected findings in recent years ranging from the elegant unravelling of the molecular basis of colour vision defects to the subtle complexity of the retinoblastoma gene. The role of crystallins in congenital cataract and of the rhodopsin molecule in retinitis pigmentosa are discussed, illustrating the importance of the "candidate gene" approach to genetic eye disease. "Reverse genetic" approaches to the cloning of genes responsible for aniridia and choroideremia exemplify the power of the new genetic techniques and signal the start of the next experimental phase, in which the functional characterization of identified genes begins. Sections on albinism, retinitis pigmentosa and collagen disorders deal w

Discusses the Effect of Automated Assessment Programs on Health Care Provision Diabetes is approaching pandemic numbers, and as an associated complication, diabetic retinopathy is also on the rise. Much about the computer-based diagnosis of this intricate illness has been discovered and proven effective in research labs. But, unfortunately, many of these advances have subsequently failed during transition from the lab to the clinic. So what is the best way to diagnose and treat retinopathy? Automated Image Detection of Retinal Pathology discusses the epidemiology of the disease, proper screening protocols, algorithm development, image processing, and feature analysis applied to the retina. Conveys the Need for Widely Implemented Risk-Reduction Programs Offering an array of informative examples, this book analyzes the use of automated computer techniques, such as pattern recognition, in analyzing retinal images and detecting diabetic retinopathy and its progression as well as other retinal-based diseases. It also addresses the benefits and challenges of automated health care in the field of ophthalmology. The book then details the increasing practice of telemedicine screening and other advanced applications including arteriolar-venous ratio, which has been shown to be an early indicator of cardiovascular, diabetes, and cerebrovascular risk. Although tremendous advances have been made in this complex field, there are still many questions that remain unanswered. This book is a valuable resource for researchers looking to take retinal pathology to that next level of discovery as well as for clinicians and primary health care professionals that aim to utilize automated diagnostics as part of their health care program.

Different animals have different visual systems and so presumably have different ways of seeing. How does the way in which we see depend on the optical, neural and motor components of our visual systems? Originally published in 1993, the mathematical tools needed to answer this question are introduced in this book. Elementary linear algebra is used to describe the transformations of the stimulus that occur in the formation of the optical, neural and motor images in the human visual system. The distinctive feature of the approach is that transformations are specified with enough rigour for readers to be able to set up their own models and generate predictions from them. Underlying the approach of this book is the goal of providing a self-contained source for the derivation of the basic equations of vision science. An introductory section on vector and matrix algebra covers the mathematical techniques which are applied to both sensory and motor aspects of the visual system, and the intervening steps in the mathematical arguments are given in full, in order to make the derivation of the equations easier to follow. A subsidiary goal of this book is to demonstrate the utility of current desktop computer packages which make the application of mathematics very easy. All the numerical results were produced using only a spreadsheet or mathematics package, and example calculations are included in the text.
