VD: vessel density. A P value < 0.05 is considered statistical significance and are shown in boldface
P1: comparisons of RAO eyes vs fellow eyes (paired student’s t test)
P2: comparisons of RAO eyes vs NC eyes (unpaired student’s t test)
P3: comparisons of fellow eyes vs NC eyes (unpaired student’s t test)
