Figure 2

ROC curves of different combinations of visual function and structure parameters for discriminating Parkinson’s disease. AD = amplitude density; IT = implicit time; R1 = ring1; R2 = ring2; R3 = ring3; MD = mean deviation of visual field, MRT = macular retinal thickness; MV = macular volume; RNFL = retinal nerve fiber layer.
