Autoregulation of the macular capillary blood flow was investigated using a blue-field entoptoscope and OCVM suction cup system. The perfusion pressure was reduced by elevation of the intraocular pressure with a Langham's suction cup placed on the temporal sclera. The results showed that the autoregulatory response maintains the macular capillary blood flow velocity until the perfusion pressure is reduced to approximately 25 mmHg. The Closed-loop gain of the autoregulatory response functions at a perfusion pressure as low as approximately 10 mmHg, below which it did not work well.
使用蓝域眼内镜和OCVM吸盘系统研究了黄斑部毛细血管血流的自动调节。通过将兰厄姆吸盘置于颞侧巩膜上以升高眼压来降低灌注压。结果显示，自动调节反应可维持黄斑部毛细血管血流速度，直至灌注压降至约25 mmHg。自动调节反应的闭环增益在低至约10 mmHg的灌注压下发挥作用，低于此灌注压则效果不佳。
