Blood circulation in the central retina was examined in 30 eyes suffering from glaucoma, using the entoptic phenomenon to count leucocytes travelling through the retinal capillaries in the macula area. Two measurements were taken for each eye at different intraocular pressure levels and the results were compared with each other. They showed that reduction of an originally high intraocular tension level significantly increased the blood flow. In a control group of healthy eyes in a similar group of patients insignificant changes in blood flow were recorded. There was thus a direct linear relationship between reduction of intraocular pressure and relative increase in blood flow with a strongly positive correlation (r = 0,74). Hence an effective autoregulation of blood flow in relation to changes in intraocular pressure could not be demonstrated.
对30只患有青光眼的眼睛进行了视网膜中央血液循环检查，利用眼内现象来计数通过黄斑区视网膜毛细血管的白细胞。在不同眼压水平下对每只眼睛进行了两次测量，并将结果相互比较。结果显示，原本较高的眼压水平降低后，血流量显著增加。在一组类似患者的健康眼睛对照组中，记录到血流量无明显变化。因此，眼压降低与血流量相对增加之间存在直接的线性关系，且相关性很强（r = 0.74）。因此，未能证明血流量相对于眼压变化存在有效的自动调节。
