To clarify whether high blood pressure (BP) and high body mass index (BMI) are associated with elevated intraocular pressure (IOP), a cross-sectional and longitudinal study was conducted. This epidemiological study analyzed health examination data obtained between 2001 and 2005 from 896 Japanese individuals (aged 32-79 years) who had not undergone any ocular surgery or medical treatment for hypertension, ocular hypertension, or glaucoma. Multiple-regression analysis of our cross-sectional data showed that systolic and diastolic BP (SBP and DBP) and BMI had significant and near-significant positive associations with IOP in men (p＜0.05) and women (p＜0.1). Our longitudinal study from analyses of covariance found that the adjusted mean level of changes in IOP tended to increase with increased levels of SBP, DBP, and BMI in men (p＜0.1). In women also, changes in SBP and BMI tended to be positively related with that of IOP (p＜0.1). The results of this study suggested that BP and BMI were positively associated with IOP in middle-aged and older Japanese. Therefore, management of BP and improvement of obesity might be especially important to Japanese patients with open-angle glaucoma or ocular hypertension as they have a higher incidence of normal-tension glaucoma than Europeans and Americans.
