运动与眼压

Physical exercise and intraocular pressure

早在20世纪60年代，就有研究者发现运动可以降低青光眼患者的眼压。不同的运动方式、不同的运动强度及运动后的时问对降眼压的效应不同。青光眼患者和正常人运动后的降眼压幅度和持续时间存在一定的差异。运动降低眼压的机制与去甲肾上腺素浓度降低、胶体渗透压增加、一氧化氮与内皮素及β2受体基因多态性等因素有关。临床眼科医师在对青光眼患者进行药物和手术治疗的同时，应鼓励患者尝试运动疗法，如散步、慢跑、骑单车等。

In the 1960s, it had been observed that physical exercises could reduce the intraocular pressure （IOP） in patients with glaucoma However, the effect of IOP reduction varied with exercise type and intensity, as well as the duration after exercise. Difference of lowering the IOP in glaucoma patients and healthy people were also observed. The mechanisms of reducing the IOP by exercise were very complicated and believed to be associated with the lower concentration of norepinephrine, the rising of colloid osmotic pressure, the co-action of nitric oxide and endothelin after exercise, and also related to the gene polymorphism of β2-adrenergic receptor. Physical exercise, such as jogging, walking and bicycle riding, could be suggested as a complimentary therapy in addition to the pharmaceutical and surgical therapies available for glaucoma patients, even though the mechanism for lowering lOP is not clear enough.
