A blind person can detect objects again after optogenetic treatment
Doctors performed genetic therapy to add a light-sensing molecule to a human eye. The gene they added, called a grimson, comes from a single-celled algae species that is able to perceive and go into sunlight.
The idea of adding the gene, Roska says, is to design retinal cells called ganglia so that they can respond to light so that visual signals can be sent to the brain.
Strategies funded by the French company GenSight Biologics require patients to wear a set of electronic glasses that receive ambient light contrasts and then project the image onto the retina at high intensity using the exact wavelength of yellow-orange light. triggers the gimson molecule.
