Although mice could see on a temporary basis, this is a very important discovery in this field of research to regain vision. The Group of researchers consists of scientists from the universities of Berkeley, Munich and Washington, managing to restore the vision of mice blind. treatment is based on a substance called chemical AAQ, which got cells blind ” of the to be sensitive to light back to the retina.

The substance is activated by light, and this modifies the flow of ions through channels by activating neurons. Scientists discovered that the mice regained the light sensitivity, because the pupils of mice are crontrajeron to direct. This research must continue to assess the effectiveness of the treatment, since the effect of the substance takes 24 hours...
