With 129 mununcipal workers in Maebashi City, Gunma Prefecture, the measurement of blood pressure was monthly carried out for 2 years, and changes in it were investigated with reference to findings of eye ground. Namely it was studied what sorts of fiindings of eye ground were correlated with what sorts of change in blood pressure, and what sorts of the findings of eye ground were obtained from whose blood pressure were judged as normal by casual measurement. The results were as follows : More than half of those above 50 years of age were found hypertensive, and especially in age group of 50-59 years, the frequency was highest. As to fundus lesion, the rate of abnormality increased after 50 years of age, and the rate was highest in age group of 50-59 years. Among those who were engaged in office works, hypertension and positive fiindings of eye ground tended to be encountered frequently. But in those with slight abnormal eye ground, blood pressure returned to the normal in many cases, whereas those with severe abnormality were apt to have persistent hypertension. Further, the course of change in blood pressure was mostly satisfactory in the former, and unsatisfactory in the latter. In general, the more remarkable was findings of eye ground and the higher was blood pressure at the first measurement, the more unsatisfactory was the course of change in blood pressure.
