Mean thickenss by software analysis (μm)
Measure Control (N = 28) DM with no DR (N = 46) Mild DR (N = 28)
RT 284.07a ± 13.40 279.02 ± 14.26 271.46a ± 26.23
CS 260.61 ± 24.15 245.46 ± 24.36 254.68 ± 46.90
GCL + IPL 91.14bc ± 32.89 79.78b ± 7.36 73.96c ± 10.61
RNFL 45.93de ± 24.60 30.41d ± 3.46 29.78e ± 5.57
  1. RT: Retinal thickness; CS: Central subfield of ETDRS grid; GCL + IPL: ganglion cell layer and inner plexiform layer; RNFL: Retinal nerve fiber layer.
  2. The letters a, b, c, d, eindicate significant difference between the groups (a: p = 0.032, b: p = 0.039,c: p = 0.003,d: p < 0.001 , e: p < 0.001).
