Eyes on dopamine

Dopamine-restoring drugs already used to treat Parkinson’s disease may also be beneficial for the treatment of diabetic retinopathy, a leading cause of blindness in adults, researchers have discovered. The results were published recently in Journal of Neuroscience.

Diabetic retinopathy affects more than a quarter of adults with diabetes and threatens the vision of more than 600,000 people in the United States. Doctors had previously thought most of the impairment of vision in diabetic retinopathy came from damage to the blood vessels induced by high blood sugar, but had known that dopamine, a vital neurotransmitter in the brain, was also important in the retina.

“There was some evidence already that dopamine levels were reduced in diabetic retinopathy, but what’s new here is: we can restore dopamine levels and improve visual Ray Ban outlet function in an animal model of diabetes,” says Machelle Pardue, PhD, associate professor of ophthalmology at Emory University School of Medicine and research career scientist at the Atlanta VA Medical Center.
