Objective To examine relationships of blood pressure with central retinal arteriolar equivalent (CRAE) and central retinal venular equivalent (CRVE) among 242 police officers. Methods Computerized retinal images of each eye were taken. Mean values of CRAE and CRVE were compared across hypertension status categories using ANOVA and ANCOVA. Associations of mean arterial blood pressure (MABP) with CRAE and CRVE were obtained using regression models. Results CRAE were significantly narrower in officers with uncontrolled hypertension (142.8±2.7 μm), compared to those with controlled hypertension (153.6±2.7μm, p=0.0013) and those with no hypertension (156.4±1.0μm, p≤0.0001) after covariate adjustment. CRAE decreased by 3.43 μm for each 5 mmHG increase in MABP (p≤0.0001). Conclusion Uncontrolled hypertension was significantly associated with narrower retinal arterioles. No association was observed with retinal venules.
