The effect of change of posture on the level of the intraocular pressure was studied in 22 patients who had suffered 'occlusion' of a central retinal vein, 14 patients with occlusion of a tributary of the central vein, and 23 normal subjects. The results showed a significant difference in behaviour between subjects in the control group and both groups of patients with retinal vein occlusions. In general it appears that the normal person maintains a relatively rigid control of ocular tension. The eyes are maintained at similar pressures which vary very little with change in posture. In contrast, the patient with a retinal vein occlusion (whether central or tributary) does not appear to have a similar degree of control. The eyes are not maintained at closely similar pressures, and each eye shows a change of pressure with change of posture which is considerably greater than that shown by the eyes of normal persons. The significance of these results is discussed with particular reference to the clinical association of retinal vein occlusion and chronic simple glaucoma, in which latter condition a similar lack of postural control of the intraocular pressure is found.
对22例视网膜中央静脉“阻塞”患者、14例视网膜中央静脉分支阻塞患者以及23名正常受试者，研究了姿势改变对眼压水平的影响。结果显示，对照组受试者与两组视网膜静脉阻塞患者的表现存在显著差异。总体而言，正常人似乎对眼内压保持相对严格的控制。双眼眼压维持在相似水平，随姿势改变变化很小。相比之下，视网膜静脉阻塞患者（无论是中央静脉阻塞还是分支阻塞）似乎没有类似程度的控制能力。双眼眼压并非维持在非常接近的水平，且每只眼睛的眼压随姿势改变而发生的变化明显大于正常人的眼睛。本文特别参照视网膜静脉阻塞与慢性单纯性青光眼的临床关联对这些结果的意义进行了讨论，在后一种病症中也发现了类似的眼内压姿势控制缺失情况。
