Association between Retinal Nerve Fiber Layer Thickness and Eye Fatigue

Figure 2

Box plots showing the distribution of retinal thickness in subjects with and without eye fatigue. There was a significant difference in mean macular ganglion cell complex thickness between subjects with and without eye fatigue (P = 0.014, unpaired t-test) (left panel), while the full macular thickness was not different between groups (P = 0.976) (right panel). The horizontal line in each diagram indicates the median value. The height, positive error bar, and negative error bar of each box indicate the 25th–75th percentiles, maximum values, and minimum values, respectively. F(-) = without eye fatigue; F(+) = with eye fatigue.
