New Discovery! Eye Proteins Associated with Diabetic Retinopathy

The discovery of certain eye proteins in people with diabetic retinopathy has moved scientists one step closer to unlocking the mystery behind one of the leading causes of vision loss and blindness in the United States. Diabetic retinopathy affects eyesight because of changes in the  blood vessels of the retinas. The retina is located at the back of the eye and relays messages about what you see to the brain for processing.  To date, researchers have been challenged to understand the biochemical process that contributes to the blood vessel alterations.
In a study published by the American Chemical Society, researchers examined eye fluid from people with and without diabetic retinopathy.  Thirty-seven proteins were identified that showed changes consistent with the most severe form of diabetic retinopathy (proliferative diabetic retinopathy). The protein concentrations were either higher or lower in people with diabetic retinopathy than those without the condition.  Researchers hope that by further studying the proteins , they can learn more about the disease and treatments.
