Lu J, et al. - Researchers investigated whether there was an association between the time in range (TIR)—defined as the percentage of time spent within the glucose range of 3.9–10.0 mmol/L during a 24-hour period]—assessed by continuous glucose monitoring (CGM) and diabetic retinopathy (DR) by analyzing data collected from 3,262 patients with type 2 diabetes. Findings showed that patients with more advanced DR had significantly less TIR and higher measures of glycemic variability, and suggested that there exists a relationship between TIR assessed by CGM and DR in type 2 diabetes.
