Optic inflammation 'needs better therapies'

Scientists are attempting to develop protection for the optic nerve during traumatic brain injury by studying the nerve's response to such damage.

The researchers, from Georgia Health Sciences University, said that there are not enough treatments available for traumatic optic nerve damage other than high-dose steroids.

When the optic nerve is injured through an event such as traumatic brain injury, the immune system kills off the neurons which can be damaging within the central nervous system where there is little regeneration.

Additionally, the nerve injury produces energy source adenosine in order to fight the inflammation.

Dr. Gregory Liou, of the university, explained how the adenosine could be strengthened to increase the anti-inflammatory effect.

"All we are doing is trying to boost the self-defense system that is already there," he explained.

One such condition that causes inflammation of the optic nerve is optic neuritis which also includes reduced or lost vision in one eye, swelling of the optic disk, eye pain and reduced colour vision.
