目的探讨慢性高原病(CMS)患者视网膜改变的特征,为高原眼病临床诊断提供参考依据。方法对移居海拔4300m、5100m、5380m10个月以上的407名男性青年采用CMS国际诊断标准[1]进行流行病学调查,将确诊为CMS的179人采用YZ-6B型强光源检眼镜分别进行视网膜检测,并行图表式记录。结果CMS患者眼底视网膜乳头充血、动脉痉挛、静脉怒张、视网膜渗出程度均为,发生率100%。结论CMS患者眼底呈暗红色,主要以动静脉比例增大为主,血管柱紫青或紫黑色,尤其是静脉增宽,似腊肠状,出现血管增多,并见乳头显著充血,网膜渗出。与急性缺氧期视网膜改变极其相似。
Objective To investigate the characteristics of retinal changes in patients with chronic high altitude sickness (CMS) and provide reference for the clinical diagnosis of plateau diseases. Methods A total of 407 male adolescents who migrated to an altitude of 4300m, 5100m and 5380m for more than 10 months were surveyed by using the CMS international diagnostic criteria [1]. 179 patients diagnosed with CMS were examined by YZ-6B strong light source ophthalmoscope Detection, parallel chart recording. Results In the patients with CMS, retinal hyperemia, arterial spasm, venous anger and retinal exudation were all occurred in 100% of cases. Conclusions The fundus of patients with CMS is dark red, mainly the proportion of arteriovenous increases, the vascular column purple or purple, especially the veins widened, sausage-like, there is increased blood vessels, and see the nipple hyperemia, omental exudation . And acute hypoxia retinal changes are very similar.
