Retinal degenerative diseases lead to blindness due to loss of the “image capturing” photoreceptors, while neurons in the “image-processing” inner retinal layers are relatively well preserved.  Information can be reintroduced into the visual system using electrical or optical stimulation of the surviving inner retinal neurons.  Some electronic retinal prosthetic systems have already been tested in human patients and approved for clinical use, while more advanced technologies are being developed . Alternatively, light sensitivity can be artificially introduced into retinal neurons using opto-genetic or opto-pharmacological methods.  Several optogenetic approaches have been successfully tested in animal models of retinal degeneration. I will review the current state of art with each of these approaches, their challenges, technological solutions and perspectives of restoration of sight to the blind.
