Correlations of systolic blood pressure with BFV of the retina and conjunctiva. The BFV of the conjunctiva had no significant correlation with systolic blood pressure (r = 0.03, P = 0.85, a). On the other hand, BFV of retinal arterioles was positively correlated with systolic blood pressure (r = 0.34, P = 0.01, b). No significant correlation was found between the BFV of retinal venules and systolic blood pressure (r = 0.21, P = 0.13, b)
