Короткий опис (реферат):
Structures of eye bottom were extracted using
multiscale texture gradient method and color characteristics of
macular zone and vessels were verified in CIELAB scale. The
difference of average values of L*, a* and b* coordinates of CIE
(International Commision of Illumination) scale in patients with
diabetes and healthy volunteers was compared. The average value of
L* in diabetic patients exceeded such one in the group of practically
healthy persons by 2.71 times (P < 0.05), while the value of a* index
was reduced by 3.8 times when compared with control one
(P < 0.05). b* index exceeded such one in the control group by 12.4
times (P < 0.05). The integrated index on color difference (ΔE)
exceeded control value by 2.87 times (P < 0.05). More pronounced
differences with ΔE were followed by a shorter period of MA
appearance with a correlation level at -0.56 (P < 0.05). The
specificity of diagnostics raised by 2.17 times (P < 0.05) and negative
prognostic index exceeded such one determined with the expert
method by 2.26 times (P < 0.05).
