Bionic Eye and Retinitis Pigmentosa
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2019, Vol 19, Issue 3
Abstract
According to Fernandez et al. [1] approximately 140,000 blind people in the industrial countries could benefit from visual neuroprosthesis [1]. In the last quarter of a century, attention has been paid to retinal neuroprostheses with active stimulation (with external source of energy). Retinal neuroprostheses are structurally very similar. It is a small camera system placed in glasses that transmits the captured information to a video chip. This video chip translates them into electrical voltage changes and transmits them to a retinal implant consisting of a certain number of electrodes to stimulate retinal cells. Photodiodes built into the microchip can also be used instead of the camera. Even those require an external source of energy. The microchip with the electrodes can be implanted epiretinally, subretinally or suprachorioideally [2- 4]. Similarly, the axons of these cells can also be stimulated with electrodes located in the sheath around the optic nerve Another level is the lateral geniculate body which can be stimulated by deep electrodes or more recently by a cluster of microelectrodes [5]. Similarly, also the visual cortex using the surface or deep electrodes according to Philip et al. [6].
