This completely revised and updated, Third Edition, reflects the quickly advancing technology of spectral domain optical coherence tomography (OCT). Incorporated within over 600 pages are a multitude of updated features unique to this Third Edition including over 1,200 color images, state-of-the-art technology, and case presentations. These elements cohesively work together to successfully demonstrate the retina in normal and diseased states using spectral domain OCT. The text's primary objective is to illustrate the appearance of the eye in health and disease, comparing conventional clinical technologies using spectral domain OCT imaging. This method introduces the clinician to the manifestations of disease as indicated by OCT, while presenting the more familiar fundoscopic and fluorescein angiographic views side-by-side. This text will provide a clinical reference for eyecare professionals, as well as retina and glaucoma specialists, that shows how to utilize and interpret OCT imaging to enhance diagnostic sensitivity and specificity. As well as to enhance therapeutic decision making and monitor the outcome of treatment.
