Prehypertension may be common in patients with central serous chorioretinopathy

To test an observational hypothesis that patients with central serous chorioretinopathy (CSCR) may have a tendency towards hypertension compared with normal individuals. In this case-control study we evaluated resting blood pressure in 32 patients with CSCR and compared it with that in 32 healthy controls in a standard laboratory environment. Differences in resting systolic and diastolic blood pressure were measured. Mean systolic blood pressure was 123.56+/-4.8 in the CSCR group and 113.63+/-12.62 in the control group. Mean diastolic blood pressure was 84.75+/-10.2 in the CSCR group and 76.75+/-0.4 in the control group. The difference in mean blood pressure values between the two groups was statistically significant. Patients with CSCR may be predisposed to prehypertension. Hence they should be advised on lifestyle modification and followed up periodically for early detection of progression to stage 1 or 2 hypertension.
