It is a group of genetic disorders that affect the ability of the retina to respond to light, is inherited and causes a slow loss of vision.
Treatment: it is not possible to stop the loss of vision caused by retinitis pigmentosa, but the visual rest of the patients can be used thanks to low vision aids). a) Gene therapies: these are in an advanced stage of research and consist of replacing the defective gene with a healthy one to prevent the disease from progressing. b) Cellular therapies: based on the introduction of healthy cells into the affected retinal tissue, to which they must be integrated. This strategy is independent of the molecular cause and, once the difficulties of the process are overcome, it can be applied in more severe stages of the disease than gene therapies. c) Retina chip: bionic vision already makes it possible to perceive light stimuli to facilitate the location and identification of objects in blind people. We are working on models that provide increasingly higher resolution of the images and that allow the definitive leap of this technology that artificially stimulates the retina.
