Generally speaking, physicians have the impression that intraocular pressure (IOP) in winter is higher than in summer, but it is very difficult to evaluate the difference between summer and winter IOP statistically, because the treatments of glaucoma patients are changed according to their conditions. We compared the winter and summer IOP of normal subjects and of several glaucoma patients who had no therapy or no change in therapy. The subjects were divided into four groups, i.e., 20 eyes of the normal group, 17 eyes of the ocular hypertensive group, 24 eyes of the primary open angle glaucoma group, and 52 eyes of the low tension glaucoma group. The difference in mean IOP between summer and winter were evaluated for each subject. In all groups, the mean difference in mean winter IOP was significantly higher. The ups and downs of IOP were greater in the ocular hypertensive group and the primary open angle glaucoma group than in the normal group and the low tension glaucoma group. These results suggest that the seasonal variation of IOP should be taken in consideration when treating glaucoma patients.
一般来说，医生们有这样的印象，即冬季的眼压（IOP）高于夏季，但很难从统计学上评估夏季和冬季眼压的差异，因为青光眼患者的治疗会根据其病情而改变。我们比较了正常受试者以及几名未接受治疗或治疗未改变的青光眼患者的冬季和夏季眼压。受试者被分为四组，即正常组20只眼、高眼压组17只眼、原发性开角型青光眼组24只眼和低眼压性青光眼组52只眼。对每个受试者评估夏季和冬季平均眼压的差异。在所有组中，冬季平均眼压的平均差异均显著更高。高眼压组和原发性开角型青光眼组眼压的起伏比正常组和低眼压性青光眼组更大。这些结果表明，在治疗青光眼患者时应考虑眼压的季节性变化。
