Retinal prostheses in degenerative retinal diseases

Degenerative retinal diseases may lead to significant loss of vision. Age-related macular degeneration (AMD) and retinitis pigmentosa (RP), which eventually affect the photoreceptors, are the two most common retinal degenerative diseases. Once the photoreceptorcells are lost, there are no known effective therapies for AMD or RP. The concept of retinal prosthesis is to elicit neural activity in the remaining retinal neurons by detecting light and...
