| Summary: |
Purpose: The aim of
the study was to examine the colour vision and contrast
sensitivity of the patients with type II diabetes,
without retinopathy.
Material and methods: The study included 25
patients with diabetes without retinopathy or any other
ocular diseases (50 eyes were tested). The control group
was represented by 15 healthy people. Both anomaloscopic
test, Rayleigh (red – green axis) and Moreland (blue –
yellow axis) were used to test colour vision. Contrast
senstivity was measured in spatial frequency of 2, 4, 6,
12 and 18 cycles/ degree by using Gratings Contrast
Sensitivity Test.
Results: The contrast sensitivity was lower in
the spatial frequency of 6, 12 and 18 cycles/ degree.
The colour vision changes were observed (especially in
the blue-yellow axis) more often than in healthy people.
Conclusions: The colour vision examination and
contrast sensitivity measurement in patients with
diabetes without retinopathy can detect visual function
disturbances in the early, subclinical stage of the
disease. |
