Tight Glucose Control Protects Vision
Keeping blood glucose levels in the normal range can reduce the risk for eye damage in people with type 2 diabetes—even if control wanes with time. That was the finding from a 2010–2014 examination of 1,310 people who had previously participated in the landmark ACCORD trial, a study comparing standard and intensive glucose control. Progression of a diabetes-related eye condition called retinopathy occurred in 12.7 percent of people who had been in the study’s standard-care group (with an average A1C of 7.7 percent), compared with 5.8 percent of those in the former intensively controlled group (the average A1C during the study was 6.4 percent). By the time this four-year examination of the study participants was conducted, the degree of diabetes control had equalized in the two groups to close to 8 percent. Clearly, achieving tight control, as directed by your doctor, can have long-term positive effects.
