Blood pressure, hypertension and retinopathy in a population

This study provides precise estimates of the prevalence of retinal lesions in nondiabetic persons with and without hypertension. The findings suggest that retinopathy (6% in normotensives and 11% in people with hypertension), and retinal arteriolar narrowing (11% in normotensives and 19% in people with hypertension) are common. Further longitudinal study is necessary to evaluate the public health significance of these findings.
