In the last few years there have been many papers in vision science journals about visual factors in dyslexia, but these findings have not been widely disseminated to the professionals who care for people with dyslexia. Dyslexia and Vision aims to provide a straightforward summary of work in this field for teachers, educational psychologists, child psychologists, and paediatricians. The primary purpose of the book is to provide these professionals with the information they need in order to offer balanced, insightful advice for people in their care. Eyecare professionals themselves are often bewildered by the plethora of claims and anecdotes in this field. A secondary purpose of the book is to provide, in appendices, a balanced "evidence-based" review of the literature for eyecare professionals.

Developing healthy visual-motor abilities is more difficult in the complex stimulus of today's world than ever before. Our visual experiences can be overwhelmed by the vast complexity of artificial colors and sounds which did not exist in our ancestors' lives. Much more time is spent indoors, exposed to a myriad of unnatural colors, movement and imagery. We hibernate inside, interacting with machines instead of being out in the sunlight, looking at the far horizons, exploring natural environments. More and more time is spent sitting rather than moving, watching rather than doing. Here is a book that has: An overview of the development of vision, with a checklist of warning signs of vision problems-based on the studies of behavioral optometry; A discussion of the importance of integrating all the senses equally in the development of optimal visual skills, rooted in the field of occupational therapy; Practical, playful activities designed to improve visual skills in both adults and children. Excellent for use at home, in the clinic, at school, or amid outdoor settings

The information is easily accessible, presented in a clear format with areas of importance highlighted. Key sections for the trainee include: Clinical Skills, Aids to Diagnosis, Investigations and their Interpretation, Perioperative Care, Theatre Notes and Therapeutics. The wider practise of eye-care is supported by expanded chapters on Refractive Ophthalmology, Vision in Context, Evidence Based Ophthalmology and Resources for Ophthalmologists. Now including newer treatments across a range of specialities such as SMILE, gene-therapy and retinal prostheses, as well as greater emphasis on the evidence underlying current clinical practice and guidelines, this handbook has never been more essential for all those working in eye-care. Whether you want to learn about patient-reported outcomes, identify a surgical instrument, interpret a statistical test, or diagnose and treat ophthalmic emergencies, you will find it here. Whatever your role in caring for patients with eye disease: ophthalmologist, optometrist, orthoptist, ophthalmic nurse, or other health profession - discover for yourself why this handbook has become the 'go-to' resource for tens of thousands of eye-care professionals around the world.

A revision and reference text for pre-registration and postgraduate optometrists, covering procedures for investigating heterophoria, heterotropia, vergence and accommodative anomalies. The text covers the diagnosis of disorders of voluntary eye movement, nystagmus and supranuclear defects, paresis and non-paralytic incomitancy. Both motor and sensory anomalies are discussed together with syndromes involving oculomotor anomalies. Clinical management is outlined in protocols in an easily assimilable form. The second edition has additional information for final year undergraduates. Amblyopia treatment has been extended to cover new American optometric methods. Strabismus surgical techniques are now included. There are two new chapters on vision training and case management which will interest optometrists and orthoptists involved in sports vision and in developmental vision therapy. Pre-registration optometrists will find the chapters on routine orthoptic assessment and the PQE examination of particular interest.

In this thoroughly updated fourth edition, award-winning contact lens author, lecturer, and researcher, Professor Nathan Efron, presents an easily accessible, systematic account of how to identify, understand, and manage contact lens complications.

Visual dysfunctions can limit children's concentration, self esteem and school success as they struggle to understand fundamentals such as colors, letters and how to judge distance. With the right help, these obstacles can be overcome, allowing children to reach their full potential and see the world clearly. This accessible book explores how visual problems develop and how they can be reversed through effective and efficient visual therapy. It breaks down myths surrounding visual dysfunction and explains in straightforward terms the various conditions that could be impacting a child's perception, even if they have perfect sight. The visual therapy used in behavioral optometry retrains the brain to perform visual skills more effectively. In these pages there is clear guidance on the array of therapies, techniques and aids available, all of which can make a profound difference to a child's life. This introductory guide to behavioral optometry will be a welcome resource for parents and professionals in search of options to help a child who is experiencing visual problems.

This book is a comprehensive account of the most recent developments in modern ophthalmic optics. It makes use of the powerful matrix formalism to describe curvature and power, providing a unified view of the optical and geometrical properties of lenses. This unified approach is applicable to the design and properties of not only spectacle lenses, but also contact and intraocular lenses (IOL). The newest developments in lens design, manufacturing and testing are discussed, with an emphasis on the description of free-form technology, which has surpassed traditional manufacturing methods and allows digital lenses to be specifically designed with the unique requirements of the user. Other important topics which are covered include modern lens materials, up-to-date lens measuring techniques, contact and intraocular lenses, progressive power lenses, low vision aids, ocular protection and coatings. Providing a broad overview of recent developments in the field, it is ideal for researchers, manufacturers and practitioners involved in ophthalmic optics.

Dyslexia affects about 10% of all children and is a potent cause of loss of self-confidence, personal and family misery, and waste of potential. Although the dominant view is that it is caused by specifically linguistic/phonological weakness, recent research within the field of neuroscience has shown that it is associated wtih visual processing problems as well. These discoveries have led to a resurgence in visual methods of treatment, which have shown promising results. 'Visual aspects of dyslexia' brings together cutting edge research from a range of disciplines - including neurology, neuroscience, and the vision sciences, to present the first comprehensive review of this recent research. It includes chapters from leading specialists which, in addition to reporting on the latest research, show how this knowledge is being successfully applied in the development of effective visual treatments for this common problem. Sections within the book cover the role of eye movements in reading, visual attention and reading, the neural bases of reading, and the relationship between visual stress and dyslexia. Making a valuable contribution in helping us develop a deeper understanding of dyslexia, this is an important book for those in the fields of psychology, neuroscience, and education.
