Can the fractal dimension be applied for the early diagnosis of non-proliferative diabetic retinopathy? BJMBR
Kunicki,A.C.B.; Oliveira,A.J.; Mendonça,M.B.M.; Barbosa,C.T.F.; Nogueira,R.A..
The fractal dimension has been employed as a useful parameter in the diagnosis of retinal disease. Avakian et al. (Curr Eye Res 2002; 24: 274-280), comparing the vascular pattern of normal patients with mild to moderate non-proliferative diabetic retinopathy (NPDR), found a significant difference between them only in the macular region. This significant difference in the box-counting fractal dimension of the macular region between normal and mild NPDR patients has been proposed as a method of precocious diagnosis of NPDR. The aim of the present study was to determine if fractal dimensions can really be used as a parameter for the early diagnosis of NPDR. Box-counting and information fractal dimensions were used to parameterize the vascular pattern of the...
