Study examines why episodes of low blood sugar worsen eye disease in people with diabetes

People with diabetes who experience periods of low blood sugar — a common occurrence in those new to blood sugar management — are more likely to have worsening diabetic eye disease. Now, researchers at Johns Hopkins Medicine, the University of Colorado School of Medicine, and the University of Maryland, say they have linked such low blood sugar levels with a molecular pathway that is turned on in oxygen-starved cells in the eye.
