Vision enhancement systems

Abstract This chapter provides an overview of visual system properties in health and disease, with an emphasis on the stages in visual-signal processing that are most commonly affected by disease and dysfunction. It then provides an overview of current approaches to vision restoration and of approaches that promise to migrate from the lab to the clinic in the coming years. In a third section, the potential roles for engineered cells and tissues in this restoration process are discussed. The chapter closes with an estimate of the developments that can be expected to occur in the next 5–10 years.
