Exercise can slow or prevent vision loss, study finds


There have been many studies on how exercise is good for physical and mental health. In a new study, researchers have found it can slow or prevent the development of macular degeneration (causes loss in the center of the field of vision) or other common causes of vision loss such as glaucoma and retinopathy diabetic.

The University of Virginia (UVA) School of Medicine study found that exercise reduced harmful blood vessel proliferation by up to 45% in the eyes of lab mice, which is a key factor eye diseases.

“It has long been debated whether maintaining a healthy lifestyle can delay or prevent the development of macular degeneration. The way this question has always been answered has been to survey people, ask them what they eat and how much exercise they do,” said Bradley Gelfand, PhD, of the Center for Advanced Vision Science at the UVA.

A first test comparing mice that voluntarily exercised with those that did not found that exercise reduced blood vessel proliferation by 45%. A second test, to confirm the results, revealed a 32% reduction.

Gelfand noted that the onset of vision loss was often associated with decreased exercise. “It’s fairly well known that as people’s eyes and vision deteriorate, their tendency to engage in physical activity also decreases. It can be difficult to study in the elderly. To what extent does one cause the other? says the researcher.

The researcher revealed his secret motivation behind the research. “One of the reasons I wanted to do this study was kind of selfish. I was hoping to find a reason not to exercise. It turned out that exercise is really good for you.
