Fig. 4

Low macular sensitivity distribution and sensitivity parameters comparison in microperimetry. a Percentile chart of low sensitivity percentage in total, Group 1, and Group 2. The percentage of low sensitivity of mean retinal sensitivity ≤ 25 dB (orange area) are plotted on the bar. b The comparison of retinal sensitivity for each area is found along the x-axis. The difference between the two groups is plotted (***, P < 0.001). MS, mean sensitivity
