本文用眼底照相法对47例正常人、50例糖尿病患者和15例非高血压或糖尿病的动脉粥样硬化患者的视网膜血管对吸氧的收缩反应进行了比较研究。糖尿病组显示动脉和静脉的反应性降低，如对氧气的收缩反应降低所示。糖尿病受试者的视网膜动脉反应性显著降低，即使没有视网膜病变或高血压。随着视网膜病变的出现，动脉反应性进一步降低。单纯动脉粥样硬化患者视网膜血管反应性无明显变化。
By means of fundus photography, a comparative study has been made of the constrictor response of retinal vessels to the inhalation of oxygen in 47 control subjects, 50 diabetic patients, and 15 persons with atherosclerosis unassociated with hypertension or diabetes. The diabetic group showed decreased reactivity of both arteries and veins, as indicated by a decreased constrictor response to oxygen. Retinal arterial reactivity was significantly reduced in diabetic subjects, even in the absence of retinopathy or hypertension. With the appearance of retinopathy, arterial reactivity was still further reduced. The patients with uncomplicated atherosclerosis did not show significant changes in retinal vascular reactivity.
