Insights
Increased blood pressure variability (BPV) is linked to central serous chorioretinopathy (CSCR). This study found higher 24-hour and daytime BPV in CSCR patients, suggesting BPV as a new risk factor.
Area of Science:
- Ophthalmology
- Cardiology
- Physiology
Background:
- The choroid's vascular nature makes it susceptible to hemodynamic changes.
- Blood pressure variability (BPV) may contribute to choroidal dysfunction and central serous chorioretinopathy (CSCR) development.
Purpose of the Study:
- To investigate short-term BPV over 24 hours in patients with acute CSCR compared to healthy controls.
Main Methods:
- A cross-sectional comparative study involving 50 CSCR patients and 60 healthy controls.
- 24-hour ambulatory blood pressure monitoring with measurements every 15 minutes (day) and 30 minutes (night).
- Statistical analysis of mean variability index (VI), systolic blood pressure (SBP), and diastolic blood pressure (DBP) during different periods.
Main Results:
- No significant differences in mean 24-hour, daytime, or night-time SBP and DBP between groups.
- Significantly higher mean 24-hour and daytime VI for SBP and DBP in the CSCR patient group.
- Multivariate logistic regression identified 24-hour and daytime VI as independent risk factors for CSCR.
Conclusions:
- Patients with CSCR exhibit significantly higher 24-hour and daytime SBP and DBP variability compared to controls.
- Elevated BPV may represent a novel risk factor for the pathogenesis of CSCR.
Background/Objectives:
The choroid, mostly composed of vascular structures, can be directly affected by systemic hemodynamic changes. Blood pressure variability (BPV) may factor into choroidal dysfunction, which can be associated with the pathogenesis of central serous chorioretinopathy (CSCR). The aim of our study was to investigate short-term BPV over 24 h in patients with acute CSCR versus healthy controls.
Subjects/Methods:
Our cross-sectional comparative study included 50 patients with CSCR (i.e., patient group) and 60 healthy individuals (i.e., control group). In all participants, 24-h ambulatory blood pressure was monitored every 15 min during the day and every 30 min at night. Mean variability index (VI), systolic blood pressure (SBP), and diastolic blood pressure (DBP) during the day, at night, and across the 24-h period were subjected to statistical analyses.
Results:
Mean 24-h, daytime, and night-time SBP and DBP did not significantly differ between the groups. The mean 24-h and daytime VI values for SBP and DBP were significantly higher in the patient group than in the control group, whereas the mean night-time VI values for SBP and DBP between the groups were similar. Multivariate logistic regression models revealed that the VI values for 24-h and daytime SBP and DBP emerged as independent risk factors for developing CSCR.
Conclusion:
Our study revealed that variabilities in 24-h, daytime SBP and DBP were significantly higher in patients with CSCR than in controls. Our results thus suggest that increased BPV may be a new risk factor for the development of CSCR.
