According to researchers from the National Institutes of Health, glucose concentrations are effective predicting diabetic retinopathy. Likewise, both one- and two-hour concentrations showed similar efficacy.
The study authors assessed longitudinal and cross-sectional cohorts of 1,703 and 2,895 individuals, respectively. They found that the incidence and prevalence of diabetic retinopathy changed in a similar manner across distributions of one- and two-hour plasma glucose concentrations. Both showed similar values in identifying incident and prevalent diabetic retinopathy.
The takeaway from the study was that one-hour plasma glucose is a useful way to predict retinopathy risk, and its predictive value is similar to that of the two-hour plasma glucose.
These findings were published in Diabetes Care on April 5, 2018.
