高原红细胞增多症眼部表现观察

Clinical Observation of Ocular Manifestation in High Altitude Polycythemia

目的探讨高原红细胞增多症患者的眼部表现及其意义。方法收集我院215例高原红细胞增多症患者及210体检正常人群进行裂隙灯结膜血管扩张检查及间接检眼镜眼底检查,观察结膜血管扩张、视网膜静脉扩张、视盘改变及视网膜出血、渗出情况,进行上诉体征的阳性率的比较。结果高原红细胞增多症患者出现结膜及眼底改变的阳性率高于正常人群,并随红细胞增多症程度的增加,结膜血管扩张、视网膜静脉改变、视盘改变及视网膜出血、渗出的程度均随之加重,差别有统计学意义(P<0.05)。结论高原红细胞增多症的眼部表现与高原红细胞增多症的疾病程度密切相关。

Objective To obverse the ocular manifestation of high altitude polychthemia. Methods 215 patients diagnosed as high altitude polychthemia and 210 normal people as observation group were examed by slitlamp and indirect ophthalmoscopy to obverse the dilation of conjunctival vessels,the distorting of retinal veins,the border of optic disc,retinal hemorrhages and exudation. The positive rates of ocular signs were analyzed.Result The positive rates of ocular signs in high altitude polychthemia were higher than in the observation group. With the aggravation of severity of high altitude polychthemia,the ocular manifestation were more obvious. There were significant differences between the groups（ P〈0. 05）.Conclusion The ocular manifestation of high altitude polychthemia were closely relate to the severity of high altitude polychthemia.
