Autoregulation of retinal blood flow was studied in seven normal volunteers. The stimuli to autoregulation used were hyperoxia and hypoxia under controlled conditions of isocapnia. Macular blood flow was measured using the blue field entoptic phenomenon and retinal artery and vein diameters were measured using a computerised digitising system. Results under conditions of isocapnic hypoxia showed a 38 per cent average increase in blood flow and an increase in diameter of 8.2 per cent and 7.4 per cent in retinal arteries and veins respectively. In hyperoxia blood flow fell by an average of 36 per cent and retinal artery and vein diameter decreased by 5.6 per cent and 10 per cent respectively.
对七名正常志愿者的视网膜血流自动调节进行了研究。在等碳酸血症的控制条件下，用于自动调节的刺激因素为高氧和低氧。使用蓝场视内现象测量黄斑血流，并使用计算机数字化系统测量视网膜动脉和静脉直径。等碳酸血症性低氧条件下的结果显示，血流平均增加38%，视网膜动脉和静脉直径分别增加8.2%和7.4%。在高氧状态下，血流平均下降36%，视网膜动脉和静脉直径分别下降5.6%和10%。
