Scientists restore vision in a mouse

Through the years, there have been reports of various cures for blindness, but this new one seems to be definitive. Researchers and scientists from the University of Berkley have managed to restore the vision of a mouse after injecting a chemical directly in their eyes.

This chemical is known as AAQ, and acts as a kind of photo interrupter, and which does is to unite the ion channel proteins with cells from the surface of the retina. When exposed to light, the chemical changes the flow of ions in the eye, activating neurons and returning the light to the mouse.

If that sounds confusing, it simply means that a small dose of AAQ, the mouse was able to regain his sight temporarily. The effect lasted only a few hours, but of course this fact has led scientists to improve the chemical and are now working on an enhanced version they hope will last a couple of days.

We hope to have more news soon.
