  • Of the 125 diabetics, fundus could not be examined in either eye in 4 owing to dense cataract or small pupil, and data regarding duration of diabetes were not available for 2. These 6 subjects are not included in this table.

  • NPDR=non-proliferative diabetic retinopathy; PDR=proliferative diabetic retinopathy.

  • Percentages do not add up exactly to the total because of rounding.
