The link between geomagnetic field activity (GMA), solar activity and intraocular pressure (IOP) in healthy individuals was investigated. The IOP of 485 patients (970 eyes) was recorded over three nonconsecutive years (1979, 1986, 1989) which were characterized by maximal solar activity (1979, 1989) or minimal solar activity (1986). The measurements were also correlated with four categories of GMA activity: quiet (level I0), unsettled (II0), active (III0), and stormy (IV0). Participants were also differentiated by age and sex. We found that IOP was lowest on days of level IV0 (stromy) GMA. The drop in IOP concomitant with a decrease in GMA level was more significant during periods of low solar activity and in persons over 65 years of age. There was a trend towards higher IOP values on days of levels II0 and IV0 GMA in years of high solar activity. Differences between the sexes and among individuals younger than 65 years were not significant. Our results show an interesting aspect of environmental influence on the healthy population.
研究了健康个体的地磁场活动（GMA）、太阳活动与眼压（IOP）之间的联系。在三个不连续的年份（1979年、1986年、1989年）记录了485例患者（970只眼）的眼压，这些年份的特点是太阳活动最大（1979年、1989年）或最小（1986年）。测量结果还与四类GMA活动相关：平静（I0级）、不稳定（II0级）、活跃（III0级）和剧烈（IV0级）。参与者也按年龄和性别进行了区分。我们发现，在GMA为IV0级（剧烈）的日子里眼压最低。在太阳活动低的时期以及65岁以上的人群中，眼压随GMA水平降低而下降的幅度更为显著。在太阳活动高的年份，II0级和IV0级GMA的日子里眼压有升高的趋势。65岁以下的性别和个体之间的差异不显著。我们的结果显示了环境对健康人群影响的一个有趣方面。
