体位与眼压波动

Body position and intraocular pressure fluctuation

眼压较大波动是造成青光眼视神经损伤的重要因素，而眼压波动受多重因素影响，体位是其中之一。本文通过介绍体位变化时间对眼压的影响、连续体位变化对眼压的影响、不同卧位对眼压的影响、倒立举重等对眼压的影响、正常人与青光眼患者体位变化眼压比较等来阐述体位变化与眼压的关系，从上巩膜静脉压、血压、眼内容物与前房深度、眼灌注压、激素等五个方面解释体位变化如何影响眼压，并阐述了体位影响眼压的意义。

The fluctuation of intraocular pressure（IOP） is an important factor causing glaucomatous optic nerve injury, and posture is one of the most important factors affecting IOP. The effects of body posision on lOP is receiving more and more attention. This article reviews the research progress about the posture impacts on IOP. The objective is to explain the relationship between position change and IOP by presenting the effects of postural changing time, continuous postural change, different supine position, handstand and weightlifting, and summarize how the postural change affect the IOP from five aspects： episcleral venous pressure, blood pressure, intraocular contents and anterior chamber depth, ocular petfusion pressure, and the change of adrenalin.
