| Summary: |
Purpose: The evaluations of color vision
sensitivity in children with type I diabetes mellitus without retinopathy.
Material and method: We examined 96 young patients. They was divided into
three groups: I: 35 children from 7 to 16 years old with insulin- dependent diabetes
mellitus duration of 1- 8 years, II: 30 children with type I diabetes lasting more then 8
years, III - 31 non - diabetic subjects as a control - matched for age and sex, without
visual or systemic symptoms.
The examinations of colour vision sensitivity were done with the IF -2AII - color
Anomaloscope. In all cases were tested the dynamic blue- green equation of Moreland and
two variables were determined: setting (matching) range (SR), calculated mid point
(matching mid point) (CMP).
Results: In the blue - green equation setting range (SR) was
significantly (p<0.01) enlarged in the II group (diabetes mellitus duration >8
years) and calculated mid point (CMP) was shifted but no significant. The results indicate
a diminution of the colour discriminating sensitivity in the short wavelength half of the
visible spectrum and diminution of the blue cone sensitivity in early diabetic
retinopathy.
Conclusions: Blue - green colour vision testing with the anomaloscope may
serve as an additional test in the diagnosis of early diabetic retinopathy in children
without vascular changes at the eye fundus. |
