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.

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.

Contains the proceedings of the XVI International Symposium on Retinal Degeneration (RD2014), to be held July 13-18, 2014 at the Asilomar Conference Center in Pacific Grove, California. A majority of those who will speak and present posters at the meeting will contribute to this volume. The Symposium addresses the blinding diseases of inherited retinal degenerations, which have no effective treatments and age-related macular degeneration, which has no cures, despite the fact that it is an epidemic among the elderly, with 1 in 3-4 affected by the age of 75. The RD2014 Symposium will focus on the exciting new developments aimed at understanding these diseases and providing therapies for them. 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; molecular genetics; and developing potential therapeutic measures such as gene therapy and neuroprotective agents for potential pharmaceutical therapy; and several sight restoration approaches, including optogenetics. While advances in these areas of retinal degenerations will be included, several new topics either were in their infancy or did not exist at the time of the last RD Symposium, RD2012. These include many new developments in sight restoration using optogenetics, retinal or RPE cell transplantation, stem cell approaches and visual prosthetic devices. In addition, major advances will be presented in other basic mechanisms in age-related macular degeneration, several new aspects of gene and antioxidant 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 RD2014 meeting and included.
