We evaluated changes in intraocular pressure in eyes with primary open-angle glaucoma after inversion into a totally dependent position with the head down and compared them with the changes intraocular pressure in healthy nonglaucomatous eyes. Five minutes after inversion, intraocular pressure increased from 16.8 mm Hg +/- 2.8 (sitting) to 32.9 mm Hg +/- 7.9 in normal eyes and from 21.3 mm Hg +/- 2.3 (sitting) to 37.6 mm Hg +/- 5.0 in glaucomatous eyes. Although visual fields were unchanged after inversion, glaucomatous eyes may be particularly susceptible to such changes and unable to withstand the transient but significant increase in intraocular pressure that occurs after assuming an inverted position. We recommend that patients with ocular hypertension or glaucoma refrain from this activity.
我们评估了原发性开角型青光眼患者的眼睛在头朝下倒置成完全依赖体位后眼压的变化，并将其与健康非青光眼患者眼睛的眼压变化进行了比较。倒置五分钟后，正常眼睛的眼压从16.8毫米汞柱±2.8（坐位）升高到32.9毫米汞柱±7.9，青光眼患者的眼压从21.3毫米汞柱±2.3（坐位）升高到37.6毫米汞柱±5.0。尽管倒置后视野没有变化，但青光眼患者的眼睛可能对此类变化特别敏感，无法承受倒置后眼压出现的短暂但显著的升高。我们建议高眼压或青光眼患者避免此项活动。
