Stroke Warning: Retinal Artery Blockage!

Retinal Artery Blockage May Warn of Impending Stroke A certain retinal vessel disease may be a warning of an impending stroke! When an artery or vein in the retina becomes blocked or “occluded” it can be a sign of more serious health issues that need to be looked-quickly! A central retinal artery occlusion (CRAO) is a disease of the eye where the flow of blood through the central retinal artery is blocked. Patients suffering from a central artery occlusion experience a sudden, severe, painless loss of vision in one eye. While there can be several different causes of the blockage, most often a central retinal artery occlusion is caused by unhealthy carotid arteries which supply the head and neck with oxygen. Unhealthy carotid arteries are those that have atherosclerosis, are narrowed and filled with a waxy fatty substance that forms plaques that can break off and end up in the retinal circulation. Retinal artery occlusion is a significant warning of a stroke risk and indeed more than 15…

AMD & Low Glycemic Diet


Does a Low Glycemic Diet Help AMD?

Researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University also believe that the study, published in the journal PNAS, points to potential biomarkers of AMD. These can be used to predict when a person is at risk for this disease, which is the leading cause of vision loss in adults over the age of 50. Using a mouse research model, the researchers observed that a high–glycemic diet resulted in the development of many AMD features, including loss of function of cells at the back of the eye called retinal pigmented epithelial atrophy (RPE) and of the cells that capture light, called photoreceptors-both of which are precursors to Dry AMD, whereas a low–glycemic diet did not. Importantly, switching from a high–glycemic diet to a low–glycemic diet arrested damage to the retina. The authors of the study suggested that these experimental results may indicate that switching from a high–glycemic diet to a low–glycemic one is beneficial to eye health in people that are heading towards developing AMD.
