职业性激光接触对视觉系统的影响

Occupational laser exposure affected workers' visual system

    摘要
  • 摘要:
    目的 调查低剂量激光接触者眼睛健康状况, 了解职业接触散射或反射激光危害程度, 为职业病防治提供参考。
    方法 采用现况调查法, 选择2家电子加工企业从事激光雕刻岗位作业的113名员工为接触组, 2家企业从事非激光接触岗位作业的118名员工为对照组, 检测激光接触岗位工人眼部位置激光强度, 对2组人员进行眼科检查。
    结果 检测8个点的激光辐照度在(1.2~4.4)×10-5 W/cm2之间, 平均值为(2.4 ±1.1)×10-5 W/cm2, 均未超过职业卫生接触限值。2组视力功能指标(近视力、远视力、色觉、视野)差异均无统计学意义(P>0.05), 但激光接触组晶状体异常率和眼底异常率高于对照组, 差异有统计学意义(P < 0.01)。
    结论 低剂量激光对接触者眼睛存在影响。应尽快制定激光作业职业健康监护规范, 保护劳动者健康。

     

    Abstract:
    Objective To investigate the adverse effects of occupational exposure to low intensity laser on workers' eyes.
    Methods Totally 113 workers occupational exposed to laser irradiation and 118 workers without any records of exposure to known occupational hazards in 2 electronic processing enterprises were studied. The laser intensities at individual workplaces were detected and ophthalmologic examinations were carried out.
    Results Eight workplaces where workers exposed to laser radiation were measured, and it was found that the range of these laser intensities was (1.2-4.4)×10-5 W/cm2 with the average(2.4 ±1.1)×10-5 W/cm2, which was lower than national exposure limit. The ophthalmologic examinations showed that the abnormality of both lens and fundus of laser-exposed workers was significant higher (P < 0.01), while there was no difference of visual function index (near visual acuity, distant visual acuity, color vision, and visual field) between the exposed workers and the others(P>0.05).
    Conclusion Low intensity laser exposure could cause injury of eyes. More attention should be paid to these exposed workers and the corresponding occupational health surveillance standard should be established.
