体位与眼压

Posture change and intraocular pressure fluctuation

青光眼的发病机制复杂,而眼压是已知的最重要的危险因素.眼压越高,眼压波动越大,青光眼性视神经损害越严重.眼压波动会受到多重因素的影响,如情绪、运动、昼夜节律等.近些年来,体位变化对眼压波动的影响得到越来越多的关注.本文主要综述各种不同体位对眼压的影响,药物和手术、年龄对眼压随体位变化的影响,体位变化对几类特殊人群眼压的影响,并对眼压随体位变化的机制进行了分析探讨.

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 postureinduced IOP fluctuation are also discussed in this article.
