Light Sensitivity Restored in Mice: A new drug could replace the hardware currently required to restore some semblance of sight.
The drug, called AAQ (for acrylamide-azobenzene-quaternary ammonium) when injected right into the eyes of mice allowed bonded with proteins in the eye and mimicked the function of the rods and cones which allow us to see.
Even in mice with few rods and cones the drug was able to restore response times to light to near-biological levels. "It's not possible to ask a mouse how well it sees, so it's impossible to say quite what was restored by the drug. But there are reasons to think that the performance should be pretty good," the article said.
Before we get too excited about the new drug, there's a catch: it only lasts for 24-hours before another injection is needed. via Ars Technica
