Mechanisms by which omega-3 fatty acids benefit eye health revealed

Omega-3 fatty acids provide many health benefits.  Over the last several years, research involving omega-3 fatty acids has revealed a positive, direct effect on eye health. Retinopathy, age-related macular degeneration (AMD), as well as other diseases that affect the nerves and tissues of the eye, negatively impact the lives of millions, often leading to impaired vision or blindness.
A new study in Science Translational Medicine (February 2011) reviewed the impact of omega-3 fatty acids on eye health and the pathways by which its beneficial effects occur.  It was found that 4-HDHA, a metabolite of the omega-3 fatty acid, DHA, selectively promoted the growth of healthy blood vessels while inhibiting the growth of abnormal (unhealthy) vessels.  Researchers believe these findings further highlight the beneficial effects of this omega-3 fatty acid and may serve as a foundation for exploring new treatment regimes for eye-related diseases as well as other diseases that affect the body.
