The researchers assessed the impact of exercise on the condition of the eyes of mice.
American scientists from the University of Virginia found a link between physical activity and the slowing or complete stop of development of macular degeneration, glaucoma, diabetic retinopathy and other eye diseases that lead to blindness, reports the Chronicle.info with reference to the Correspondent.
The study found that sport reduces the threat the growth of blood vessels 45%.
It is emphasized that the excessive growth of blood vessels, which is the main cause of macular degeneration and other eye diseases was reduced in mice on the background of regular running in a wheel.
“This is the first experimental evidence that exercise can reduce the severity of macular degeneration, which is the main cause of vision loss in the elderly,” said the study authors.
At the same time, the researchers noted that the increased load did not bring more benefits. The effect was achieved at low levels of exercise.
The reasons for the relationship between visual acuity and physical activity can be many, say the authors. For example, physical activity could contribute to the increased blood flow to the eyes.
Scientists plan based on the results of a study to develop options for the treatment of patients with vision problem whose effectiveness would be similar to playing sports.
“The fact that often diseases of the eye develop from fairly elderly people who not all loads can be forces,” they explained.
Earlier in Hong Kong University of science and technology, scientists have created an artificial eye that is virtually identical to the structure of the human body.
