Although the pathogenesis of glaucoma is complicated and multifactorial, elevated intraocular pressure (IOP) remains the most important known risk factor. The higher the IOP and the larger the IOP fluctuation, the more damage to the optic nerve. IOP fluctuation can be affected by many factors, such as emotion, exercise and circadian rhythm, etc. Recently, the effects of postural change on IOP fluctuation are receiving more and more attention. This article reviews the effects of different body positions on IOP fluctuation, the effects of surgery, medications and aging on posture-induced IOP fluctuation and the effects of postural change on IOP fluctuation of certain special groups. The possible mechanisms of posture-induced IOP fluctuation are also discussed in this article.
尽管青光眼的发病机制复杂且具有多因素性，但眼内压（IOP）升高仍然是已知的最重要风险因素。眼压越高且眼压波动越大，对视神经的损害就越严重。眼压波动会受到许多因素的影响，如情绪、运动和昼夜节律等。最近，体位变化对眼压波动的影响受到越来越多的关注。本文综述了不同体位对眼压波动的影响、手术、药物和衰老对体位性眼压波动的影响以及体位变化对某些特殊人群眼压波动的影响。本文还讨论了体位性眼压波动的可能机制。
