Scientists closer to a drug to prevent loss of vision

Scientists closer to a treatment for the two most common causes of vision loss after a successful experiment in mice, say U.S. researchers. Activation of certain proteins in the eyes, preventing damage to the blood vessels that can lead to blindness. The study deals with macular degeneration and diabetic retinopathy - two of the main diseases associated with blood vessel problems. Most of these diseases, the people in later life. Researchers have identified a protein Robo4, which, as it turned out played an important role in the formation of strong, working blood vessels. Scientists injected proteins in mice to study the effects of age-related macular degeneration and diabetic retinopathy. Scientists have found that damage to the blood vessels have been prevented, and in some cases was a complete regression of the disease. According to the scientists do not yet know whether the human body react to the protein, and what side effects they may have, but in any case this is a great opening and a step towards the creation of drugs to treat and prevent the causes of loss of vision.
