远航海勤人员屈光不正性视疲劳原因调查分析

Investigation and analysis on the cause of ametropic visual fatigue in the naval service personnel during prolonged deployment at sea

目的了解远航海勤人员屈光不正情况及原因,为防治屈光不正提供科学依据。方法对486名水面舰艇人员和潜艇人员按年龄和持续远航天数各分为3个组,分析屈光不正检出率情况。结果 486名海勤人员屈光不正检出率为31.5%(153/486),其中水面舰艇人员屈光不正检出率为29.5%(87/295),潜艇人员屈光不正检出率为34.6(66/191),两类海勤人员屈光不正检出率差异无统计学意义(χ2=1.378,P>0.05)。水面舰艇人员3个年龄组之间(χ2=4.402,P>0.05)及潜艇人员3个年龄组之间屈光不正检出率差异均无统计学意义(χ2=3.076,P>0.05)。水面舰艇人员各远航组之间(χ2=27.03,P<0.01)及潜艇人员各远航组之间(χ2=18.74,P<0.01)屈光不正检出率差异均有统计学意义。结论持续性长期远航容易引起屈光不正,应做好远航海勤人员视疲劳的防治工作。

Objective To understand the situation and reason of ametropia in the navy service personnel during prolonged de -ployment at sea , and to provide scientific evidence for the prevention of ametropia .Methods In accordance with age and sustained de-ployment days , 486 naval surface vessel personnel and submariners were divided into 3 groups, and then the detection rate of ametropia was analyzed accordingly .Results The detection rate of ametropia among the 486 naval personnel was 31.5%（153/486）, of which the rate of ametropia for the surface vessel personnel was 29.5%（87/295）and that for the submariners was 34.6%（66/191）.No sta-tistical significance could be noted in the detection rate of ametropia , when comparisons were made between the 2 groups （χ2 =1.378, P〉0.05）.Statistical significance could neither be found in the detection rate of ametropia between the three age groups of the surface ship personnel （χ2 =4.402, P〉0.05） and the three age groups of the submariners （χ2 =3.812, P〉0.05）.However, statistical sig-nificance could be noted in the detection rate of ametropia between various prolonged deployment groups of surface vessels （χ2 =27.03, P〈0.01）and various prolonged deployment groups of submariners （χ2 =18.74,P〈0.01）.Conclusion Sustained deployment at sea could easily induce ametropia among navy service personnel , with this reason , attention should be paid to the prevention and treatment of visual fatigue during prolonged deployment at sea .
