Pediatric retinal diseases are not simply retinal diseases that occur in children; rather, they are unique disorders that often are…
not found in adults. This textbook of the pediatric retina offers in-depth guidance on congenital and acquired diseases of the retina in the pediatric population. It is organized according to disease onset and timing, as well as anatomy. All chapters are written by leading authorities in the field from both the pediatric and the retinal perspective. A multidisciplinary approach to the topic is adopted, and critical information is included on disease classification and diagnosis, pathophysiology, genetics, complications, and prognosis. Pediatric Retina will be a useful source of information for pediatric ophthalmologists, retina specialists, and other eye care providers who care for children.Par Carlos Pavesio. 2017
This book offers a concise but comprehensive overview of scleritis, with up-to-date information on all aspects, including diagnosis and treatment.…
Fundamental features of the pathogenesis of scleral inflammation are first discussed as a basis for understanding the therapeutic strategies. Detailed descriptions are then provided of clinical manifestations, the complications that can arise during the course of the disease process, and the best way to manage them. An individual chapter is devoted to infectious scleritis and its management, this being an uncommon but serious condition that may result not only in loss of vision but also in loss of the globe itself. The diagnostic approach to and various management options for scleritis are then discussed extensively, with coverage of local and systemic therapy and new strategies, including biologics. Apart from the potential impact on vision, inflammation of the sclera carries a risk of association with systemic diseases, some of which can prove fatal if not promptly recognized and managed. This book is designed to allow ophthalmologists to easily identify the condition and the signs indicative of a more severe problem. It will thereby assist in safe and effective management, and help in preserving vision and life.Herpes zoster ophthalmicus (HZO) is a common disease in the elderly and the immunosuppressed, with potentially devastating sequelae. Diagnosis of…
HZO is clinical but almost all its manifestations are non-specific. The exception is varicella-zoster virus epithelial keratitis, which is frequently the only indicator of the true nature of the disease. This book is unique in presenting high-magnification images, obtained by non-contact in vivo photomicrography, that capture the distinctive features of varicella-zoster virus epithelial keratitis in HZO. Both the morphology and the dynamics of the corneal epithelial lesions are splendidly documented, including in patients with HZO sine herpete and recurrent disease. Three rare cases of ocular surface involvement in acute HZO are included, and the final chapter carefully compares varicella-zoster virus epithelial keratitis in HZO and the lesions of herpes simplex virus.Par David A. Weinberg, Adam J. Cohen. 2011

This book deals with a potentially sight threatening complication - rupture of the posterior capsule - during cataract surgery. This handbook covers…
the management of this problem from 3 perspectives: 1. Identifying patients at higher risk and measures to manage such patients by surgical discipline 2. Intraoperative management of posterior capsular rupture (PCR) to minimize long-term complications 3. Post-operative care for a patient who has a PCR Cataract surgery is the most commonly performed surgical procedure in ophthalmology and despite tremendous technical and technological advancements, PCR still occurs. PCR occurs both in the hands of experienced senior surgeons and the neophyte surgeons, although with a higher frequency in the latter group. Additionally, certain types of cataracts are prone to this development. If managed properly in a timely manner the eventual outcome may be no different from that of an uncomplicated case. However, improper management may lead on to serious complications with a higher incidence of permanent visual disability. Written for experienced and not-so-experienced eye surgeons alike to understand and manage PCR.Par Henry F. Edelhauser, Uday B. Kompella. 2009

This book aims to build concepts and create a solid foundation in the field of optical coherence tomography (OCT) for…
the general ophthalmologists as well as for the resident trainees and fellows. The chapters are written by leading international authorities in a style comprehensible to a broad audience. Numerous clinical pictures and SD-OCT scans help elucidate various clinical entities. OCT is the optical analog of ultrasound imaging and has emerged as a powerful imaging technique that enables non-invasive, in-vivo, high-resolution, cross-sectional imaging in retinal tissue. A new generation spectral domain optical coherence tomography (SD-OCT) technology has now been developed, representing a quantum leap in resolution and speed, achieving in vivo optical biopsy. i. e. the visualization of tissue architectural morphology in situ and in real time. This book encompasses the role of SD-OCT in both medical and surgical macular disorders. The book is meant coherent and comprehensive for both vitreoretinal specialists as well as general ophthalmologists.Par Jorge L. Alió. 2017
As a degenerative disorder of the eye, keratoconus can cause substantial distortion of vision, with multiple images, streaking, and sensitivity…
to light all reported by patients. Keratoconus: Recent Advances in Diagnosis and Treatment updates ophthalmologists about the innovations that have occurred within the last decade, discussing the diagnostic imaging techniques that have been developed for keratoconus diagnosis, understanding of how examination techniques are related to the evolution of keratoconus, and how to indicate the different therapeutic tools that have been created for keratoconus over the last several years. Additionally, fundamentals for new diagnostic elements, based on the mathematical, physical and biomechanical data are analyzed in depth for a better understanding of the essential diagnostic steps for the clinician to guide patients towards the most adequate therapeutic tool in the case. Modern keratoplasty techniques, assisted by femtosecond lasers or other devices, are also covered and these techniques, along with the emerging conservative treatments, have added to more precise control of the evolution of the disease.Par Bipasha Mukherjee, Hunter Yuen. 2017
This handbook on orbital, lacrimal and eyelid emergencies deals with such situations in a practical manner guiding the ophthalmologists in…
accurate handling and making them more proficient and confident in managing vision and life-threatening emergencies. With 51 chapters and more than 150 images, this book covers all the eye emergencies that generalist and specialist ophthalmologists can expect to come across in their day to day practices. It can be argued that the orbit can no more be called 'Pandora's Box' because of the unpredictable nature of its contents. This perception has changed over the years due to the advent of improved diagnostic, in particular, imaging techniques. However, since medical residency provides very little exposure to orbital and adnexal disorders, most clinicians are inexperienced and unsure about their management. Facing an emergency situation where improper management can rapidly worsen the condition leading to blindness or even death of the patient is every ophthalmologist's nightmare. The emergent nature of these conditions does not always provide for a leeway to refer these patients to an orbit and oculoplasty specialist, who are few and far between. By the time the patient reaches his destination, his vision maybe irrevocably lost. The legal implications of such mismanagement can be significant too. This book is a quick and essential resource to manage and refer eye emergencies with confidence.Par Jorge Cuadros. 2011
Digital retinal imaging performed by primary care providers and nurses, followed by remote image interpretation (teleretinal imaging), is rapidly acquiring…
a crucial role in many parts of the world as it permits the detection of major diseases, such as diabetic retinopathy and glaucoma, in patients who would otherwise be beyond the reach of a trained ophthalmologist. In this book, experts from around the world describe how digital teleretinal screening can be set up and optimally utilized. Technical issues are discussed, and the appropriate use of screening for different diseases and in different age groups is explained. The major part of the book draws upon the clinical experience of leading practitioners in a wide range of teleretinal applications. The result is a comprehensive source of high-quality information for clinicians and other health professionals who are involved in eye care delivery, so that they can assess how teleretinal screening might be applied to their working practice.Par Giuseppe Querques, Eric H. Souied. 2016
