Scientists in the US are working hard to try to prevent a particular type of damage that occurs to the eye during a car accident.
Called traumatic optic nerve damage, this occurs when the small nerve at the back of the eye gets shaken violently.
This results in swelling and inflammation, which can destroy the retinal ganglion nerves, causing vision loss and even blindness.
The Georgia Health Sciences University (GHSU) researchers have been looking at the optic nerve"s response to these injuries in an attempt to develop an effective treatment.
An A2AAR-selective agonist is being injected into the eye of mouse models in the hope that this will prevent permanent vision damage.
"All we are doing is trying to boost the self-defence system that is already there," said Dr Gregory Liou, GHSU molecular biologist.
