A significant number of important diseases, some of which are arriving at epidemic levels, such as diabetes and macular degeneration, produce, and therefore are correlated to, retinal anomalies. In this book, the authors present current research in the study of retinopathy, including nodavirus infection in viral encephalopathy and retinopathy; diabetic retinopathy in India; isoproterenol therapy improves neuronal function, vascular integrity and insulin receptor signaling in diabetic retinopathy; retinopathies and associated deafness; image mining approaches for the screening of age-related macular degeneration and diagnosis of retinal anomalies by statistical tests on OCT data.
