目的:对青海省玉树县的牧民进行干眼症初步调查和分析,了解和掌握高原牧民干眼症的发病情况。方法:随机抽查青海省玉树县三个自然村的1 500名牧民群众常规行裂隙灯检查、泪液分泌试验Ⅰ(Schirmer TearⅠTest))检查、泪膜破裂时间(BUT)检查及睑板腺功能检查。结果:1 500例被检查者中诊断为干眼症的有887名,占总人数的59.1%,高原牧民干眼症的发生率明显高于平原地区。结论:高原牧民干眼症的发病率与高原紫外线辐射强,气候干燥、寒冷、风沙大、饮食结构单一素等生活环境因素呈正相关。
Objective: To preliminary investigate and analyze the dry eye syndrome of herdsmen in Yushu County, Qinghai Province to understand and master the incidence of dry eye disease in plateau herdsmen. Methods: A total of 1 500 herdsmen in three villages in Yushu County, Qinghai Province were routinely selected for slit lamp examination, Schirmer Tear Ⅰ Test, tear film break-up time (BUT) and meibomian gland function tests. Results: Of the 1 500 cases diagnosed as dry eye, 887 were diagnosed as dry eye, accounting for 59.1% of the total. The incidence of dry eye in plateau herdsmen was significantly higher than that in the plains. Conclusion: The prevalence of dry eye disease in plateau herdsmen is positively correlated with the living environment factors such as high ultraviolet radiation intensity, dry climate, cold, big sandstorm and simple diet structure.
