Summary

This text examines the vascular anatomy and physiology of the eye as well as the assessment of ocular circulation in health and disease. It offers a cutting-edge analysis of the eye's blood supply and how it is affected by conditions such as glaucoma, age-related macular degeneration, and diabetic retinopathy. 425 illustrations -- including 250 in full color -- detail anatomy, techniques, the results of imaging studies, and more. Provides a cutting-edge analysis of the eye's blood supply and how it is affected by conditions such as glaucoma, age-related macular degeneration, and diabetic retinopathy. Describes the latest noninvasive methods for measuring blood flow, and explains how to use this advanced technology to evaluate patients. Features more than 435 illustrationsover 345 in full colorthat richly depict anatomy, techniques, imaging findings, and more. Offers the expertise of authors who have been involved extensively in the design and clinical application of new technologies for the assessment of ocular circulation.
