目的：分析不同海拔高度下急进高原者眼底视网膜健康变化。方法：观察记录内陆地区无高原居住经历的50名健康受试者分别在内陆平原60m海拔高度、西藏拉萨3500m海拔高度、羊八井4570m海拔高度眼底变化，分析急进高原对视网膜水肿、出血及血管形态影响。结果：内陆平原60m海拔时，均无眼底视网膜异常；海拔3500m时，全组9.0%视网膜静脉轻度充盈（A：V=1：2），未见视网膜出血及血管形态异常；海拔4570m时，19.0%静脉充盈扩张（A：V=1：3），2.0%眼底视网膜浅层出血，2.0%视网膜血管腊肠状改变，全组未见黄斑区出血及视力变化。结论：急进高原有可能诱发视网膜水肿、出血及血管形态异常，且海拔越高、影响越明显。

Objective Analysis the changes on the retina in different altitude for the people who suddenly came to plateau.Methods To observe the 50 healthy subjects, they are all from inland areas, no plateau living experience. Record the fundus changes in inland plains, 60 m above sea level; Lhasa in Tibet, 3500 m above sea level; Yangbaing, 4570 m above sea level. Analyzed the influence of the suddenly came to plateau, for form of retinal edema, hemorrhage and blood vessels.Results Inland plains 60 m above sea level, all without fundus retinal disorders; At an altitude of 3500 m, the whole set of 9.0% of the subjects' mild retinal vein filling (A: V = 1:2); At an altitude of 4570 m, 19.0% venous filling expansion (A: V = 1:3), 2.0% of shallow retinal hemorrhage. 2.0% retinal blood vessels like sausage shape change. Conclusions Suddenly came to the plateau could induce retinal edema, hemorrhage and abnormal vascular morphology, and the higher elevation of the influence, the more obvious.
