OCT Angiography FD Data and Comparisons for MNV versus Age-Matched Normal Control Groups

	CC FD% R1	CC FD% R2	∆ (R1 – R2)	P Value
MNV cases	54.93 ± 5.70*	50.18 ± 5.70*	4.75 ± 4.58	<0.0005*
Normal Controls	42.07 ± 4.60**	40.49 ± 4.96**	1.34 ± 1.19	<0.0005**
P value (t-test)	<0.0005	<0.0005	<0.001	–

In ring 1, the mean CC FD% measured 54.93 ± 5.70 and 42.07 ± 4.60 in the MNV and normal control group, respectively (P < 0.0005). In ring 2, mean CC FD% measured 50.18 ± 5.70 and 40.49 ± 4.96 in the MNV and normal control group, respectively (P < 0.0005). The mean difference of CC FD% between the two rings was statistically significantly greater in the MNV eyes compared with the controls: 4.75 ± 4.58 and 1.34 ± 1.19, respectively. R1 = ring 1, R2 = ring 2.
