²Celal Bayar Üniversitesi Tıp Fakültesi Göz ABD/Manisa Diabetes Mellitus is a disease which may terminated with the loss of vision because of its complications. Functional changes may occur before the recognizable retinal damage in patients witin DM. The aim of this study is determining the value and importance of FM 100 hue colour vision test in detecting early functional changes.
Fourty six diabetic patients participated to this study as the study group. The subjects in the study group were divided into two groups in respect of having retinopathy or not. Twenty four patients without retinopathy were defined as Group 1 and 22 patients with background retinopathy were defined as Group 2. A control group of 20 subjects who hand't an ocular disease expect a refraction deficit participated to the study.
These groups were compared in that FM 100 hue test. The averages of root square of total error scores were 11.65 ± 0.31 in Group 1, 12.98 ± 0.31 in Group 2 and 10.39 ± 0.21 in control group. The differance between groups was of statisfical significance (p<0.05). The root square averages of partial error scores at blue yellow quadrant was 9.16 ± 0.26 in Group 1, 10.37 ± 0.22 in Group 2 and 8.13 ±0.19 in control group. The root square averages of partial error scores at red green quadrant was 7.04+ 0.26 in Group 1, 7.49 ± 0.27 Group 2 and 6.56 ± 0.19 in control group. There was a significant differance between these groups in that partial error scores ( p<0.05).
We concluded that the retinal fonctional deficit may occur in early stages of Diabetes Mellitus. It is of great importance that FM 100 hue test in detecting this functional deficit. Keywords : Diabetes Mellitus, Colour Vision, FM 100 Hue Test
