Pterostilbene (PS), a component of blueberries, have been found to protect against dry eye disease according to a new study. The research is being presented at the 2016 Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO) this week in Seattle, Wash.
When introduced to human corneal epithelial cells, PS significantly reduced the levels of oxidative damage, which in turn reduced inflammation. Inflammation can contribute to dry eye disease, a condition that becomes increasing common with age. PS is a molecule chemically related to resveratrol.
