Abstract

In an attempt to assess the evidence of foveal color vision abnormality in diabetic patients, the foveal threshold (dB) of white, red, green, and blue color were tested in a normal control group (24persons, 48eyes) and in a diabetic patient group (30persons, 59eyes) by Allergan Humphrey Field Analyzer (Model(R) 640). The diabetic patients wrer divided into 3groups: non-retinopathic group less than 5 year duration (18eyes), non-retinopathic group less than 5year duration (18eyes), non-retinopathic group more than 5year duration (21eyes), and BDR (20eyes). In the normal control group the threshold was gradually increased in white, red, blue, and green colors and the threshold of the green color was highest but the threhold of the blue color was highest in the non-retinopathic diabetic group with more than a 5year duration and BDR There were no statistically significant differences in the threshold between the white and green color amomg groups. But, the threshold of the blue color was singificantly increased in BDR and the non-retinopathic diabetic diabetic group more than 5year duration that the normal group (p
