It combines detailed explanations with high quality clinical photographs tailor-made to help readers ace specialist oral examinations (MMed, MRCS, FRCS, FRCOphth, FAMS, FRANZCO).Co-authored by ophthalmology trainees who took the final MMed and FRCOphth (Oral) in 2016 and 2017, this is a book written by trainees, for trainees, with prominent author contribution by Prof Wong Tien Yin. This book provides invaluable guidance to readers in presenting their answers in a logical, succinct and elegant manner.Practical Guide to VIVA and OSCE in Ophthalmology Examinations aims to complement the book titled The Ophthalmology Examinations Review by Prof Tien Yin Wong to guide candidates onto the path of success in examinations. This book illustrates the answering techniques employed during examinations, utilizing clinical photographs accompanied by a full template answer script of various high yield conditions. The style and format has been intentionally designed to simulate examination conditions and to provide candidates with ample practice in preparation for the examination.Most major ophthalmic degrees require trainees to take and pass an oral ophthalmic exam. This book fills a significant void in the market for ophthalmic training, where texts combining clinical photos and actual exam answering techniques are severely lacking. Readers will be able to follow the answering techniques and examples provided within the book so as to better cope with the clinical exams.

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.

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.

Patienthood and Communication is an engagingly personal narrative detailing the author's experience living with, and adapting to, a degenerative and incurable eye disease (MacTel). Beyond the personal, this poignant story more broadly illustrates the ways in which communication enables individuals to adjust to serious health threats. Author and subject Peter Kellett highlights his important interactions with health care providers, family members, friends, colleagues, students, and others that provide shape to his journey. Kellett displays a compelling capacity for self-reflection in his descriptions of the life changes his vision loss imposes upon him, among them changes to his identity, in relationships and life plans. Adaptation and flexibility reveal themselves as central tenets of his learning to become a self-empowered patient. Perhaps the most crucial element to his adjustment is, however, positive communication, which is depicted throughout the book as the driving force in Kellett's journey into patienthood.

Advances in Ophthalmology and Optometry reviews the most current practices in both ophthalmology and optometry.

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.

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.

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.

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."
