Study suggests exercise can help to ward off macular degeneration
Experiments in mice found that exercise reduced the harmful growth of blood vessels in the eye by 45%
Writing in Investigative Ophthalmology & Visual Science, researchers from the University of Virginia School of Medicine highlighted that experiments in mice found that voluntary exercise reduced the harmful growth of blood vessels in the eye by 45%.
Study author, Dr Bradley Gelfand, highlighted that using an experimental model helped to get around the limitations of self-reporting that come with asking people about their exercise habits.
"There has long been a question about whether maintaining a healthy lifestyle can delay or prevent the development of macular degeneration,” he said.
“This study offers hard evidence from the lab for the very first time," Dr Gelfand added.
The benefits the study observed were obtained even with relatively low levels of exercise.
Researchers will next investigate why exercise has this effect on the eyes.
