Table 3 The correlations of three different methods of central corneal thickness measurements are shown. First, values of all patients were investigated for correlation. Later, separate calculations for Group I, and II were performed

  1. Group I included patients with Diabetic retinopathy, Group II included patients without diabetic retinopathy. Probability value (p) was accepted as significant if less than 5%, and was assigned with “*”
  2. OCT optical coherence tomography, SST slit scan topography, UP ultrasonography, r rho, correlation coefficient, p probability value, CI confidence interval
