某维和部队任务期内视疲劳调查分析

Investigation and analysis of asthenopia in units during their peacekeeping missions

目的调查分析我驻黎维和二级医院和工兵营官兵视疲劳发生情况,为维和官兵的眼保健、视疲劳防护提供参考依据。方法对在2011年3月1日～2011年10月20日任务期内的联合国驻黎巴嫩临时维和部队(UNIFIL)中国第七批维和医疗队及第八批维和工兵营官兵进行常规眼科体检及问卷调查,包括背景情况、眼病史、用眼习惯、上机(视频操作)习惯、体育运动、眼部视疲劳症状等,对调查结果进行统计分析。结果本次参加调查的医护人员及官兵共计159人,年龄21～51岁,平均30岁;男性142人,占89.3%,女性17人,占10.7%。调查对象平均每天上机时间5.5 h,计算机视觉综合征(CVS)发生率高达72.3%。调查对象CVS自觉症状发生率依次为眼胀及眼眶酸痛、眼干、手/肩/足/腰部疲劳、眼痒、视物模糊、眼痛、眼红、眼部异物感、畏光流泪、头晕头痛、重影、恶心呕吐。结论调查对象中CVS发生率高,症状表现多样化,其中屈光不正、眼与显示屏距离近、上机时间长等因素加重了CVS的发生。我驻黎维和部队应加强官兵的眼保护,降低视疲劳的发生,提高官兵的眼健康。

Objective To investigate and analyze the incidence of asthenopia among officers and soldiers of a level - two hospital and an engineering battalion in Lebanon during their peacekeeping missions, and to provide the reference for the eye care and prevention of asthenopia. Methods Conventional ophthalmologic examination and questionnaire were carried out among the officers and soldier of the seventh batch of peacekeeping medical corps and the eighth patch of peacekeeping engineering battalion during their peacekeeping missions in Lebanon from March 1,2011 to October 20, 2011. The investigated situations included background information,the history of eye diseases, the habits of using eyes, the habits watching computer and video, sports, and asthenopia symptoms. The results were statistically analyzed. Results There were totally 159 subjects receiving the investigation. Their average age was 30 years old ranging from 21 to 51 years old. There were 142 male ones who accounted for 89.3% and 17 female ones who accounted for 10.7%. Among those subjects, the average time for computer was 5.5 h every day; the incidence of computer vision syndrome（CVS） was 72.3%. The incidence of rational symptoms in order were eye distension and eyes sorness,eye dryness ,fatigue in hand, shoulder, foot, and waist, eye itching, blurred vision, eye pain, pinkeye, eye foreign body sensation, photophobia, dizziness and headache,ghosting, and nausea and vomiting. Conclusion The incidence of CVS is high, and the symptoms are diversified. The refractive error, close distance between eye and display screen, and long time watching display screen will induce and/or aggravate the condition of CVS. Eye protection should be strengthened in our peacekeeping forces in Lebanon in order to reduce the incidence of asthenopia and improve the eye health among the officers and soldiers.
