Retinal Imaging and Image Analysis [PDF]

IEEE Reviews in Biomedical Engineering, 2010
Many important eye diseases as well as systemic diseases manifest themselves in the retina. While a number of other anatomical structures contribute to the process of vision, this review focuses on retinal imaging and image analysis. Following a brief overview of the most prevalent causes of blindness in the industrialized world that includes age ...
