静态阈值视野是用光点做视标,检查视网膜各部位的视觉敏感度,各点静态阈值则代表着相应视网膜各点的视觉敏感度.为研究长期从事坑道作业及矿井下工作人员中央静态阈值视野的变化情况.我们对某煤矿长期从事井下工作及长期井下工作又返地面工作的人员进行了检查,井与同矿区地面工作人员进行了比较.报告如下.对象与方法对象:长期从事井下工作人员为井下各工种工人,共96人,188眼.年龄27岁～50岁,平均39.3岁.工龄8～30年,平均17.5年.返井上人员为井下工作多年,因各种原因返地面工作的工人,共20人,40眼,年龄32岁～50岁,平均40.8岁.工龄12～26年,平均18.8年.井下工作时间为10～22年,平均12.6年.对照组
The static threshold visual field is to use optical spots as the visual target to check the visual sensitivity of various parts of the retina, the static threshold of each point represents the visual sensitivity of the corresponding retinal points.In order to study the long-term engaged in tunneling work and the central staff static threshold The field of vision changes.We conducted a long-term underground coal mine work and long-term downhole work and back to the ground of the staff were inspected, and the mine with the mine staff on the ground were compared.Report as follows.Objectives and methods Object: Has long been engaged in underground work There are 96 workers in total and 188 eyes in 188 workers aged 27 to 50 years with an average age of 39.3 years and have a working life of 8 to 30 years with an average of 17.5 years.The workers on the wells returned to the well for many years and returned to the ground for various reasons Of workers, a total of 20 people, 40 eyes, aged 32 years old to 50 years old, with an average of 40.8 years of age 12 to 26 years, an average of 18.8 years downhole working time for 10 to 22 years, an average of 12.6 years in the control group
