Researchers found that vision and eye problems, such as blurry vision, dry eyes, trouble with depth perception, and problems adjusting to rapid changes in light are much more common in people with Parkinson’s disease than in people without the disorder.

“It is especially important for people with Parkinson’s to have the best vision possible because it can help compensate for movement problems caused by the disease, and help reduce the risk of falls,” said study author Carlijn D.J.M. Borm, M.D., of Radboud University Medical Centre in Nijmegen, The Netherlands. “Our study found not only that people with Parkinson’s disease had eye problems that go beyond the aging process, we also found those problems may interfere with their daily lives. Yet a majority of eye problems are treatable, so it’s important that people with Parkinson’s be screened and treated if possible.”
