Visual prostheses including artificial retinal devices are a novel and revolutionary approach to the treatment of profound visual loss. The development of the field of visual prosthesis began with cortical prosthetic devices but since then, a variety of devices which target different sites along the visual pathway have been developed with the retinal prosthesis being the most advanced. We present a review of the history of these devices, an update on the current state of play and future prospects of this field.
