Fig. 2.

(A) The mean foveal thickness difference (FTD) of normal subjects and subjects with retinal diseases. The mean FTD was greatest in the exudative age-related macular degeneration (AMD) group, and it was greater than that of normal controls (p < 0.0001, generalized estimating equations [GEE]). (B) The means and standard deviations (SD) of the differences between the virtual foveal thickness (FT) of Stratus optical coherence tomography (OCT) calculated by the conversion formulas and the actual FT measured by Stratus OCT in each group. The SD was decreased by applying conversion formulas, especially in the exudative AMD group. The horizontal lines within the white boxes indicate medians, the upper and lower limits of the white boxes indicate 75th and 25th percentiles, respectively, the upper and lower limits of the whiskers indicate 90th and 10th percentiles, and the dots over and under the whiskers indicate the values outside the 90th and 10th percentiles. ERM = epiretinal membrane; MH = macular hole; DR = diabetic retinopathy; RVO = retinal vein occlusion; CSC = central serous chorioretinopathy; CNV = choroidal neovascularization.
