摘要
目的通过《标准对数近视力表》、《log MAR近视力表》、《标准近视力表》对空勤人员进行近视力测量,评价标准对数近视力表在民航眼科中的使用情况。方法随机选择屈光不正的空勤人员180例(360眼),根据年龄分为3组,分别使用上述3种视力表测量各组人员的裸眼视力和戴镜矫正视力,数据汇总后进行统计学分析。结果裸眼视力:各组视力值经3种视力表测量后两两比较均无明显差异。戴镜矫正视力:中年空勤组的3种视力表检查数据无明显差异,青年空勤组和招飞招乘组3种视力表有差异(P<0.05)。结论经临床对比试验,3种近视力表均可应用于临床近视力检查,但针对特殊患者时,推荐使用《标准对数近视力表》,因其在设计和记录方面更为科学和准确。
Objective Through the use of standard logarithmic near visual acuity chart, Logarithms near visual acuity chart, standard near visual acuity chart for near vision measurement of aircrew, evaluation the used of standard logarithmic near visual acuity chartin civil aviation in department of ophthalmology. Methods Randomly selected ametropia aircrew in 180 cases（360 eyes）, divided into 3 groups according to ages. Respectively, using the above 3 kinds of visual acuity chart measurement the uncorrected and corrected visual acuity of personnel in each group, and analyzed with F test analysis. Results Uncorrected visual acuity：3groups had no obvious differences. Corrected visual acuity：older age group had no obvious difference. In young and young - middle age group, three kinds of visual acuity charts contain difference （P 〈 0. 05）. Conclusions Three kinds of visual acuity charts can be used in eye exam, but for the special patient, standard logarithmic near visual acuity chart is more reasonable and accurate.
