Table 1 Change in FAZ area between visits for all patients

From: Visualization of changes in the foveal avascular zone in both observed and treated diabetic macular edema using optical coherence tomography angiography

  Automated FAZ measurement Manual FAZ measurement
Average decrease in FAZ area (mm2)—deep plexus 0.09 (p = 0.019) 0.071 (p = 0.029)
Average decrease in FAZ area (mm2)—superficial plexus 0.057 (p = 0.031) 0.062 (p = 0.016)
Average decrease in FAZ area (mm2)—summated plexus 0.037 (p = 0.0006) 0.035 (p = 0.0008)
  1. The mean change in the FAZ area (in mm2) between the two visits at the deep, superficial, and summated plexuses. p values are shown in parenthesis and were calculated using paired t tests
