Artificial Retina; used to perform the function of photoreceptors
Artificial Retina Artificial retina is a kind of bionic eye and are grafted electronic devices made to stimulate sensation of sight in the eyes of person with notable retinal diseases such as retinitis pigmentosa or macular degeneration age related disease, in which the optic nerve and visual cortex are not damaged In the usual and unaffected eye, photoreceptors situated within the outer layers of the retina consist light-sensitive pigment that activate the phototransduction cascade to create neuronal signals in the occurrence of light stimuli. These signals are flown to and treated by a complicated network of neurons in the middle layers of the retina prior entering into the retinal ganglion cells in the inner layers. Axonal processes from Retinal Ganglion Cells eventually create the optic nerve to transfer the light-induced neuronal impulse to the visual cortex. In CRD such as retinitis pigmentosa, the outer covering or part of the retina in which photoreceptors reside are usua...
