In the study reported here the authors investigated the influence on ocular perfusion pressures of suction-cup oculopression, a procedure which permits oculopression without orbital compression. Patients over 50 years of age were examined before cataract extraction. Ulrich's method of ocular oscillodynamography was used to determine ocular perfusion pressures. A Mikuni and Yoneyama suction-cup dynamometer was applied for suction-cup oculopression. Ocular hypotonia following suction-cup oculopression was adequate and comparable to that achieved by other oculopression methods. After oculopression a significant increase in ocular perfusion pressures (retinal, ciliary, and diastolic) was found. However, ocular blood pressure remains constant after oculopression. Moreover, the increase in ocular perfusion pressure could not be explained by oculocardiac reflexes, because there was no change in systemic arterial blood pressure. It must be assumed, therefore, that the increase in ocular perfusion pressures is caused by a lowering of resistance, i.e., a drop in intraocular pressure.
在本文所报道的研究中，作者调查了吸盘式眼压迫法对眼灌注压的影响，该方法可在不压迫眼眶的情况下进行眼压迫。对50岁以上的患者在白内障摘除术前进行检查。采用乌尔里希的眼振荡动力学方法来测定眼灌注压。使用三邦和米山吸盘式测力计进行吸盘式眼压迫。吸盘式眼压迫后眼压降低程度适当，与其他眼压迫方法所达到的程度相当。眼压迫后发现眼灌注压（视网膜、睫状体和舒张压）显著升高。然而，眼压迫后眼血压保持恒定。此外，眼灌注压的升高无法用眼心反射来解释，因为体循环动脉血压没有变化。因此，必须假定眼灌注压的升高是由阻力降低，即眼压下降所引起的。
