Retinal Prosthesis

Retinitis pigmentosa and age-related macular degeneration, the leading causes of blindness in developed countries, are caused by degeneration of photoreceptor cells in the retina. Artificial retinas are devices that reconstruct vision by converting light into electric current and electrically stimulating the remaining retinal cells as a substitute for photoreceptor cells. The purpose of this study is to develop a three-dimensional stacked retinal prosthesis chip that constitutes a fully implanted artificial retina in the eye. The three-dimensional stacked retinal prosthesis chip has an edge enhancement function with the addition of binarization processing to achieve high image recognition performance.
