视屏作业时间与眼部症状、睫状前动脉血流动力学的相关性分析

Correlation of Visual Operation Time with Ocular Symptoms and Anterior Ciliary Artery Hemodynamics

  • 摘要: 目的

    探讨视屏作业时间与眼部症状、睫状前动脉血流动力学的相关性。

    方法

    将147名视屏显示终端(VDT)作业人员设为观察组,142例非视屏显示终端作业人员设为对照组,计算并比较两组人员的视屏作业时间、眼部症状评分以及睫状前动脉的收缩期峰值流速(PSV)、舒张末期血流速度(EDV)及阻力指数(RI);分析视屏作业时间与眼部症状评分、睫状前动脉PSV、EDV及RI值的相关性。

    结果

    观察组眼部症状评分、睫状前动脉RI值明显高于对照组,分别为6.24±1.36 vs 1.68±0.24及0.57±0.07 vs 0.55±0.07。睫状前动脉PSV、EDV值则较对照组低;视屏作业时间与眼部症状评分、睫状前动脉RI值呈正相关(r=0.62,0.66,均P < 0.05),与睫状前动脉PSV、EDV值呈负相关(r=-0.71,-0.64,均P < 0.05);眼部症状总评分与睫状前动脉RI值呈正相关(r=0.74,P < 0.05),与PSV、EDV值呈负相关(r=-0.66,-0.71,均P < 0.05)。

    结论

    长时间视屏作业易引发眼部症状的发生,并可导致睫状前动脉长期处于高阻力、低灌注状态。睫状前动脉血流灌注量越低,作业人员眼部症状越明显。

     

    Abstract: Objective

    To evaluate the correlation of visual operation time with ocular symptoms and anterior ciliary artery hemodynamics.

    Methods

    Video display terminals(VDT) workers(n=147) were enrolled as study group, and non-VDT workers(n=142) as control group. Screen operation time, ocular symptom scores, and the hemodynamic parameters of anterior ciliary artery including peak systolic velocity(PSV), end diastolic velocity(EDV), and resistance index(RI) were calculated and compared. Their correlations with screen operation time were also evaluated.

    Results

    The ocular symptom scores and anterior ciliary artery RI of the study group were significantly higher than those of the control group(6.24±1.36 vs. 1.68±0.24, 0.57±0.07 vs. 0.55± 0.07), while the anterior ciliary artery PSV and EDV were lower. The screen operation time was positively correlated with the ocular symptom scores and anterior ciliary artery RI(r=0.62, 0.66, both Ps < 0.05), but negatively correlated with the PSV and EDV(r=-0.71, -0.64, both Ps < 0.05). The total ocular symptom scores were positively correlated with the RI(r=0.74, P < 0.05), but negatively with the PSV and EDV(r=-0.66, -0.71, both Ps < 0.05).

    Conclusion

    Long-time visual operation is liable to cause ocular symptoms, and lead to a high resistance and low perfusion of anterior ciliary artery. Lower blood flow perfusion of anterior ciliary artery is associated with more obvious ocular symptoms of the workers.
