This book explains the underlying rationale for retinal and choroidal imaging in the context of systemic diseases. Various systemic diseases involve the eyes, and for some, the eyes could provide the first clue to their presence. Advances in posterior segment imaging have significantly improved our understanding of the pathophysiology and management of posterior segment diseases. However, imaging techniques like enhanced depth imaging, oximetry, adaptive optics, and retinal blood flowmetry have remained largely unexplored in connection with systemic diseases. Enhancing the available literature on the use of such imaging techniques for various systemic diseases, this handbook will help readers understand their pathomechanisms, supporting early diagnosis and more targeted therapeutic approaches. As such, it offers an essential resource for ophthalmologists, especially those with predominantly vitreo-retinal and uvea experience.

Written by experts in the field of ophthalmology, this new text assists in understanding new imaging technology and the clinical information it can provide. It allows the reader to review numerous images of various pathologies and would be of interest to retina specialists and ophthalmologists. Retinal imaging has undergone dramatic changes in the last decade, characterized by constantly improving image resolution, most notably, as it applies to macular diseases, thanks to ever evolving optical coherence tomography. However, imaging retina outside of the vascular arcades has come a long way with advent of new cameras and lenses. The most profound change has been the introduction of wide-angle angiography, which has demonstrated pathologies previously not seen or suspected and gives rise to new theories of pathophysiology of some retinal diseases. Understanding this new imaging technology and the clinical information it can provide requires a basis of knowledge and experience in associating the findings with other clinical signs in the eye and the rest of the body. Atlas of Wide-Field Retinal Angiography and Imaging helps with this experience by allowing the reader to review numerous images of various pathologies and analyzes angiographic findings in the retinal periphery. Furthermore, as this technology increasingly fills ophthalmologists'offices around the world, this book will prove to be an invaluable resource, written by experts in the field for retina specialists and ophthalmologists.​

This text presents current information on retinal and choroidal manifestations of systemic diseases from leading experts in the field. Topics include retinal and choroidal manifestations of AIDS, pediatric diseases, toxicity of systemic drugs, diseases of the gastrointestinal tract, diffuse unilateral subacute neuroretinitis (DUSN), viral and fungal diseases, sarcoidosis, Behçet's disease, carotid artery and renal diseases, changes related to pregnancy, intraocular lymphoma, and more. Their knowledge and experience will assist ophthalmologists, retina specialists, uveitis and ocular oncology specialists, and general physicians approach a level of knowledge about retinal and choroidal manifestations of systemic diseases to benefit patients in everyday clinical practice.

OCT is a relatively new imaging technique that is becoming increasingly popular among ophthalmologists in both private and academic settings. Imaging has been a slow moving area in ophthalmology for some time, but now OCT is providing another, more detailed source of demonstrable change in the eye, in diagnostic, therapeutic or post-surgical setting. OCT and ultrasound both measure advancing disease states and post surgical healing. The difference is that OCT shows more subtle changes, particularly post-surgically.
