A Better A1C Can Improve Eye Health
Blood pressure and blood glucose control may help prevent or even reverse diabetic eye disease, a study found. People with diabetes are at an increased risk for developing retinopathy, weak and leaky blood vessels in the retina that can lead to partial or complete blindness. Researchers monitored the health of 4,758 people with diabetes diagnosed at age 35 or older between 1990 and 2011, mostly with type 2. The participants were free of retinopathy at the time of their diagnosis. Over time, those with higher blood pressures and A1Cs were at a greater risk of developing retinopathy and progressing to more severe forms of the eye disease than those with lower levels. The good news: Even when people developed mild retinopathy, those with lower systolic blood pressures (top number) and A1Cs were more likely to have less additional eye damage, with some becoming free of the eye disease.
