This book reviews the current state of ocular drug therapy and future therapeutic opportunities for a wide variety of conditions, including Age-related Macular Degeneration, Diabetic Retinopathy and Macular Edema, Glaucoma, and Inherited Retinal Diseases. Retinal diseases are major contributors to moderate or severe vision impairment in adults aged 50 years and older. The respective patient populations for many of these indications is expected to significantly increase as the world population continues to grow older. An improved understanding of the etiological underpinnings of ocular degenerative diseases over the past decade has significantly bolstered ophthalmic drug discovery. In this volume, contributions from leading experts explore the unique challenges faced for ocular drug discovery and delivery providing the reader with detailed information on ocular pharmacokinetics, in vitro, ex vivo and in vivo models for retinal disease pathology and emerging gene therapy treatments. The book is intended for all researchers and clinicians who wish to increase their knowledge on the latest findings in ocular drug therapy.

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.

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.

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.

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.

This edited book focuses on the recent advances in our understanding of age-related macular degeneration (AMD), combining epidemiology and clinical diagnosis, with genetics and immunological aspects as well as the role of proteostasis and mitochondria before diving into new therapies including stem cell based approaches. AMD is a leading cause of largely incurable blindness worldwide and projected to double from 2.07 million to 5.44 million individuals by 2050 in the United States. Globally, 288 million individuals are projected to have AMD by 2040. The disease has enormous socioeconomic impact on the affected individuals, their families and the society. This book will bring together the state of the art basic science knowledge with clinically relevant findings and address the challenges for future research in AMD. The intersection of different disciplines will provide potential areas for further investigations to reduce the burden of blindness from AMD. This book offers an appealing and insightful resource for clinicians, scientists, students and fellows.

Originally published in 1925, this book embodies the results of research on red-green colour-blind subjects, supplemented by brief accounts of blue-yellow, total, and acquired colour-blindness to complete the description of the different forms of the defect. After a historical survey of previous work by such men as Dalton, Helmholtz, Rayleigh, Edridge-Green and others, the author deals with the most important theories of colour-blindness, and with a description of the tests and a discussion of their results.

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."
