A postural study was conducted in three separate groups of subjects. The first group comprised 20 women volunteers with an average age of 20-75 years. In this group, the study was conducted by the pneumatonograph only. Mean pressure recorded was 15-65 +/- 0-25 mmHg and there was an average rise of 1-4 mmHg in supine posture. Groups 2 and 3 comprised 151 non-glaucomatous and 108 glaucomatous eyes respectively in the age range of 30 to 85 years. In these two groups, the study was conducted using the PTG and the Mackay-Marg tonometer. Clinical evaluation of the Mackay-Marg with the PTG gave significant correlation, with mean Mackay-Marg readings being 1-13 mmHg higher. The intraocular pressure when changing from seated to the supine position increased on average by 2-71 and 4-04 mmHg, respectively in Groups 2 and 3 and by 2-51 and 3-72 mmHg by Vackay-Marg, suggesting a higher change in glaucomatous subjects. Pressure on resumption of sitting was found to be lower than the initial pressure. Postural change also showed some direct relationship with age in non-glaucomatous subjects.
对三组不同的受试者进行了姿势研究。第一组由20名女性志愿者组成，平均年龄在20至75岁之间。在这组中，仅通过气动眼压计进行研究。记录的平均压力为15 - 65±0 - 25 mmHg，仰卧姿势下平均升高1 - 4 mmHg。第二组和第三组分别包括151只非青光眼眼睛和108只青光眼眼睛，年龄在30至85岁之间。在这两组中，使用压平眼压计（PTG）和麦凯-玛格眼压计进行研究。麦凯-玛格眼压计与PTG的临床评估具有显著相关性，麦凯-玛格眼压计的平均读数高1 - 13 mmHg。从坐位变为仰卧位时，第二组和第三组的眼压平均分别升高2 - 71 mmHg和4 - 04 mmHg，通过麦凯-玛格眼压计测量分别升高2 - 51 mmHg和3 - 72 mmHg，表明青光眼受试者的变化更大。恢复坐姿时的压力低于初始压力。姿势变化在非青光眼受试者中也与年龄存在一定的直接关系。
