    Objective: Blood pressure variability (BPV) is considered as a novel risk factor for cardiovascular disease including left ventricular hypertrophy, vascular stiffness, and renal dysfunction. In this study, we aimed to determine the relationship between ambulatory BPV with subclinical organ damage and vascular stiffness parameters in normotensive healthy subjects. Methods: A total of 100 healthy subjects over 18 years of age were included in this cross-sectional study. We divided the participants into two groups according to the median value of the SD of mean 24-h blood pressure (BP) (Group 1: SD of mean 24-h BP 10.15). BPs of these subjects were recorded over a 24-h period using ambulatory BP monitoring. Mobil-O-Graph device was used to estimate the augmentation index (AIx), pulse wave velocity (PWV), and ambulatory BP measurement. The choroidal thickness was measured by using optical coherence tomography device. Results: The mean age of the patients was 25.4 +/- 5.0 years. Choroidal thickness was correlated with PWV, AIx, protein excretion, and SD of systolic and diastolic BP (P < 0.05). Additionally, participants with higher BP variability have lower choroidal thickness and higher AIx. Conclusion: We showed that even in normotensive subjects, BPV correlates with choroid thickness. Thus, BPV can be an early prognostic parameter for pathologic vascular changes.
