  • The value of MvD area was multiplied by 100 to enhance the readability of the table (unit for the coefficient is 0.01 mm2). Values are shown in mean (95% CI), unless otherwise indicated. Bold text indicates p value with <0.05.

  • CCT, central corneal thickness; IOP, intraocular pressure; MD, mean deviation; MvD, microvasculature dropout; SSI, Signal Strength Index; VF, visual field.
