Fig. 2From: Blue light versus green light fundus autofluorescence in normal subjects and in patients with retinochoroidopathy secondary to retinal and uveitic diseasesConfidence interval plots. Confidence interval plots for autofluorescence signal ratios (R) measured in normal (a) and RC (b) subjects. The R values are represented by blue and green circle for BAF and GAF, respectively. The R values above dotted lines represent signals more intense than the optic disc signal (dotted line). Similarly, below the dotted are located the AF signals weaker than the signal in the optic discBack to article page
