- a roadmap toward a more rational, data-driven approach to the medical management of infantile nystagmus
As the only resource effectively comprising the past 50 years of nystagmus research and therapeutic implications, Nystagmus in Infancy and Childhood will be a comprehensive and invaluable guide to for both clinicians and scientists who care for infants and children with nystagmus.

This volume from the Essentials in Ophthalmology series presents recent developments in the diagnosis and treatment of corneal disease. Its intention is not to replace the relevant textbooks, but to serve as a bridge between the primary and tertiary literature.

This well-structured volume covers the following main topics: Confocal microscopy of the cornea.- Treatment of adenoviral corneal opacities.- Conservative treatment of severe surface disorders.- Amniotic membrane transplantation.- Limbal stem cell transplantation.- Techniques in penetrating keratoplasty.- Deep anterior lamellar keratoplasty.- Corneal allograft rejection.- Infective complications following LASIK.

All topics have direct clinical importance and will not only keep ophthalmologists up-to-date, but will inform them how to treat their cornea patients with optimal (or best possible) diagnostic and therapeutic procedures.

Phillips and Ruth Thygeson were pioneers in medical research on external diseases of the human eye. Together, this husband-and-wife team shared a mutual story of extraordinary accomplishment including, among other things, the discovery of the cause and the cure of trachoma, a potentially blinding disease that affects millions of people worldwide.This comprehensive biography tells the complete story of their personal lives and careers. Beginning with each of their childhoods, the story continues through their meeting on the campus of Stanford University, their years of practicing ""frontier medicine"" in rural Colorado (where they built a log cabin with their own hands), their world travels in search of a cure for trachoma, and their considerable roles in establishing the Francis I. Proctor Foundation for Research in Ophthalmology. The story of this couple is one of a lifelong collaboration in medicine, a 70-year love affair, and an unending quest to conquer preventable blindness around the world.

Digital fundus images can effectively diagnose glaucoma and diabetes retinopathy, while infrared imaging can show changes in the vascular tissues. Likening the eye to the conventional camera, Image Analysis and Modeling in Ophthalmology explores the application of advanced image processing in ocular imaging. This book considers how images can be used to effectively diagnose ophthalmologic problems. It introduces multi-modality image processing algorithms as a means for analyzing subtle changes in the eye. It details eye imaging, textural imaging, and modeling, and highlights specific imaging and modeling techniques. The book covers the detection of diabetes retinopathy, glaucoma, anterior segment eye abnormalities, instruments on detection of glaucoma, and development of human eye models using computational fluid dynamics and heat transfer principles to predict inner temperatures of the eye from its surface temperature. It presents an ultrasound biomicroscopy (UBM) system for anterior chamber angle imaging and proposes an automated anterior segment eye disease classification system that can be used for early disease diagnosis and treatment management. It focuses on the segmentation of the blood vessels in high-resolution retinal images and describes the integration of the image processing methodologies in a web-based framework aimed at retinal analysis. The authors introduce the A-Levelset algorithm, explore the ARGALI system to calculate the cup-to-disc ratio (CDR), and describe the Singapore Eye Vessel Assessment (SIVA) system, a holistic tool which brings together various technologies from image processing and artificial intelligence to construct vascular models from retinal images. The text furnishes the working principles of mechanical and optical instruments for the diagnosis and healthcare administration of glaucoma, reviews state-of-the-art CDR calculation detail, and discusses the existing methods and databases. Image Analysis and Modeling in Ophthalmology includes the latest research development in the field of eye modeling and the multi-modality image processing techniques in ocular imaging. It addresses the differences, performance measures, advantages and disadvantages of various approaches, and provides extensive reviews on related fields.

This book discusses why specific diseases are being targeted for cell-based retinal therapy, what evidence exists that justifies optimism for this approach, and what challenges must be managed in order to bring this technology from the laboratory into routine clinical practice. There are a number of unanswered questions (e.g., surgical approach to cell delivery, management of immune response, optimum cell type to transplant) that very likely are not going to be answered until human trials are undertaken, but there is a certain amount of "de-risking" that can be done with preclinical experimentation. This book is essential reading for scientists, clinicians, and advanced students in stem cell research, cell biology, and ophthalmology.

The eleventh Symposium of the International Research Group on Colour Vision Deficiencies (IRGCVD) was held 20-23 June 1991 in Sydney, Aus tralia, ably hosted by local organizer Stephen Dain. A total of 35 talks and 10 posters were presented. Papers based on 37 of these presentations are included here, in Colour Vision Deficiencies XI. The scientific program featured sessions on three special topics, with each topic highlighted by an invited speaker. The opening session on the Genetics of congenital colour vision deficiencies began with a superb invited lecture by Charles Weitz about his pioneering work on the molecular genetics of tritanopia. The session on the second special topic, Spatial aspects of colour vision, began with the launching of a new IRGCVD tradition, as 1991 Verriest Memorial Award recipient Harry Sperling presented the first Ver riest Memorial Lecture on his recent studies of spatial discrimination of heterochromatic stimuli. Dr. Sperling reported new evidence that certain asymmetries in red-green opponent colour vision can be explained by the spatial organization of colour-opponent retinal neurons. In the third special session, on Occupational aspects of colour vision, Barry Cole took the audi ence on a fascinating tour of the historical development of colour vision standards in his invited lecture entitled 'Does defective colour vision really matter?'. In addition to the three special topics, many interesting presentations were given in topical sessions on Variations in normal colour vision, Acquired colour vision deficiencies and Colour vision tests and testing methods."

Intravitreal injections (injections into the eye) are a new form of treatment for various conditions such as age-related macular degeneration, diabetic eye disease and vascular eye problems. The use of these injections has become so widespread that most departments around the world (and particularly in the U.K) do not have enough doctors to meet the service provision demands of an ever increasing number of patients. Many departments have trialed training ophthalmic nurse practitioners as a solution and the number of such specifically trained nurses is set to rise exponentially in the future. This book is meant to be an easy to carry A5 handbook detailing all that an ophthalmic nurse practitioner needs to know about performing the procedure. It is hoped that the book will also be of benefit to trainee ophthalmologists learning the procedure.As this is an emerging area of expertise in ophthalmology, currently there exists no other books on the topic. The readers will benefit from having a single resource detailing all that they need to know about the procedure. This means that nurses will not have to cross reference multiple complicated ophthalmic textbooks. As an A5 handbook, it will be easy to carry and reference in clinics. It is deliberately meant to be concise (around 100 pages), thus concentrating only on the core knowledge required.
