According to new research, exercise may slow or prevent the development of macular degeneration and to benefit others common causes of vision loss such as glaucoma and diabetic retinopathy.
A study conducted at the Medical school of the University of Virginia, showed that physical exercise reduces the harmful growth of the blood vessels in the eyes of laboratory mice by 45%. This tangle of blood vessels is the main cause of macular degeneration and some other eye diseases.
The study represents the first experimental evidence that exercise can reduce the severity of macular degeneration, which is the main cause of vision loss, scientists say.
The results of the study
The initial test, comparing mice that performed voluntary exercise and those who do not find these exercises reduced the excessive growth of blood vessels 45%. A second test to confirm the results, showed a decrease of 32%.
Scientists are not sure exactly how exercise prevents the growth of blood vessels. According to them, the game can be a variety of factors, including increased blood flow to the eyes.
“The next step is to see how and why this happens, and see if we can develop a pill or method that will bring you the benefits of exercise without having to exercise,” write the authors.
