Notes: Numerator: patients whose poorest eye progressed to a more severe stage of diabetic eye disease since the last eye screening visit in the year before the annual report (higher number = more severe stage of disease): 1, none; 2, mild nonproliferative; 3, moderate nonproliferative; 4, preproliferative; 5, treated stable proliferative retinopathy/macular edema; 6, active proliferative retinopathy or diabetic macular edema – treated or recurrence. Denominator: all patients whose poorest eye was not labeled as being in the most severe stage of eye disease previous to the year of the annual report.

^aData collection from patients screened in ophthalmological practice started in 2013 and is still being extended to cover all practices.

Abbreviation: CI, confidence interval.
