Free radicals are molecules with an unpaired electron in the outer shell or an electron that was damaged from either attack or from a poor splitting bond. After a free radical is formed it will continue to attack other molecules, which usually results in the damage of tissue or destruction of a healthy cell. Free radicals arise normally through metabolism. However, sometimes the body s immune system will create them on purpose to neutralize viruses and bacteria. Free radicals are implicated in many ophthalmic disorders including uveitis, optic nerve damage, retinal ischemia, and macular...

All aspects of ophthalmic trauma from the lid to the optic nerve of both mechanical and nonmechanical trauma are covered in this unique book. The focus is on practical issues and incorporates cutting-edge approaches, such as temporary keratosprosthesis, artificial iris diaphragm, and prophylactic retinectomy.

This book explains and answers not simply the when, the what, and the how, but also the why questions. The information is based on epidemiologic and clinical data from evaluation to management.

All chapters are written using the standardized ocular traumatology...

Ocular inflammation presents a broad spectrum of clinical manifestations. Inflammatory activity can often be managed by drug therapy. However, inadequate medical therapy may permit the development of various complications in the eye that cannot be sufficiently treated pharmacologically. Whereas drug management demands an interdisciplinary approach with well-trained specialists, surgical treatment of ocular complications due to inflammation requires an experienced surgeon.

This book offers evidence-based information and a step-by-step guide on all relevant surgical procedures, which...

Retinal Degenerations is the result of The International Symposium on Retinal Degeneration which has become perhaps the most important research meeting in the field. The topics in this volume explore the etiology, cellular mechanisms, epidemiology, generics, models and potential therapeutic measures for the blinding diseases of retinitis pigmentosa and age-related macular degeneration.

Special focus is highlighted in the areas of Mechanisms of Photoreceptor Degeneration and Cell Death (extremely important because very little is known how or why photoreceptors die in these diseases,...

Unlike the cornea or lens, the retina is part of the central nervous system and cannot be replaced. Therefore degeneration of the outer retina is blinding, but trials using devices such as retinal implants which combine biology with technology are showing promise at restoring vision. Macular diseases are the most common cause of blindness in the developed countries. Oedema of the macula may arise in the retina, such as in diabetes mellitus or in epiretinal membrane formation, but most importantly it is age-related insufficiency of the underlying retinal pigment epithelial cell that causes...

During recent years, FAF (Fundus autofluorescence) imaging has been shown to be useful in various retinal diseases with regard to diagnostics, documentation of changes, identification of disease progression, and monitoring of novel therapies. Hereby, FAF imaging gives additional information above and beyond conventional imaging tools.
This unique atlas provides a comprehensive and up-to-date overview of FAF imaging in retinal diseases. It also compares FAF findings with other imaging techniques such as
fundus photograph, fluorescein- and ICG angiography as well as optical coherence...
