According to a new study, the percentage of time that type 2 diabetes patients spent with glucose ratings of 3.9-10.0 mmol/L per 24 hours is associated with diabetic retinopathy. Researchers evaluated the association between time in range (defined as the percent of time within a glucose range of 3.9-10mmol/L in 24 hours) and retinopathy. This was done using data from over 3,200 patients with type 2 diabetes, and glycemic variability measures were also assessed.
Of this group of participants, 780 were diagnosed with diabetic retinopathy. Patients with the most advanced cases showed significantly less time in range, and they also had higher measures of glycemic variability.
These findings were published in Diabetes Care on September 10, 2018.
