目的：综合评价参加全面体检因远视力淘汰学员与飞行学员相关医学选拔指标情况，为修订招收飞行学员视力标准提供依据。方法采取横断面调查方法，根据体检号随机抽取参加某年度飞行学员招飞全面体检因远视力淘汰的学员38名，按照同样方法随机抽取同一年度录取学员270名，整理招飞体检数据，进行人口学基本特征问卷调查，比较相关选拔指标，采用Epidata 3.02软件建立数据库，采用SAS 9.03统计软件进行数据处理统计。结果因远视力淘汰学员高考成绩达到一本和二本的人数分别为8名和22名，心理选拔总评成绩为5.67±0.75，飞行学员高考成绩达到一本和二本的人数分别为60和112名，心理选拔总评成绩为5.78±0.64，两组间差异均无统计学意义；远视力淘汰学员中低频率对比敏感度与飞行学员无显著差异，中高频率对比敏感度指标显著低于飞行学员。结论综合评价因远视力淘汰学员的心理选拔成绩、高考成绩及中低频率对比敏感度指标，有利于进一步拓展招飞生源，提高选拔质量。

ObjectiveWe aimed to evaluate the medical indexes of student pilots and been eliminated student pilots because of distant vision, in order to discover the scientific evidence of revising vision standard to recruit student pilots.MethodsA cross-section survey was conducted with the student pilots in certain year, and 270 student pilots and 38 eliminated student pilots because of distant vision were selected. All sampled respondents were interviewed with questionnaire, and were given physical examination. Database was established, cleaned and analyzed by EpiData 3.02, SAS 9.03 with double entered checking.ResultsThe student pilots and eliminated student pilots because of distant vision showed no differences in entrance examination and psychological testing performance. The CSF in frequency A and C had no differences between the two classes.ConclusionThe vision standard to eliminate student pilots should combine the psychological selection performance, entrance examination performance wit

在民航招飞学员中研究屈光度预测远视力的模型,并初步探讨中国民航招飞远视力范围标准。方法:收集1 219名中国民航飞行学院2006/2013年招飞体检学生的远视力和屈光度;以屈光度为自变量,远视力为因变量拟合指数回归曲线模型;依据模型计算不同屈光度对应的远视力预测值及其95%预测区间,并计算误差率,误差率=[(远视力预测值-实际均值)/实际均值]×100%。结果:以屈光度(x)预测远视力(y)的曲线模型为:y=0.55e0.41x+e(R2=0.968),远视力预测误差率平均为3.64%;屈光度[0.00,-3.00]D范围的远视力预测区间[0.14,0.55]与现行标准(0.3≤远视力0.7)有交叉。结论:该模型拟合效果良好,可根据屈光度预测合理的远视力范围。建议中国民航招飞时保持屈光度标准[0.00,-3.00]D不变,将远视力标准降至0.1。

AIM:To study the model to predict distant vision with diopter and to explore the distant vision standard for civil aviator recruitment in China. METHODS: The data about distant vision and diopter of 1 219 students participating in physical examination of Civil Aviation Flight University of China from 2006 to 2013 were collected. A model of index regression curve with diopter as independent variable and distant vision as dependent variable was established. The predicted value and 95% prediction interval of distant vision to specific diopter were calculated according to the model. The error rate was calculated by formula: error rate =[ ( distant vision predicted value-actual average value )/actual average value]í100%. RESULTS: The curve model with diopter to predict distant vision was: y= 0. 55e0.41x+e (R2 = 0. 968). The average error rate of predicted distant vision was 3. 64%. With diopter range [0. 00,-3. 00] D, the 95% prediction interval of predicted distant vision [ 0. 1

目的：介绍直接检眼镜彻照检查法（简称检眼镜彻照法）对角膜塑型眼及后房型可植入式隐形眼镜（implantable collamerlens，ICL）屈光矫治眼（简称ICL植入眼）筛查鉴定的有效性，并做初步理论分析。方法手持检眼镜对参加招飞或征兵体检的18342名受检者的瞳孔区进行正、侧面彻照，以瞳孔区橘黄色反光为背景，观察瞳孔区是否存在特异性暗影，暗影可用小孔照相机通过检眼镜观察孔拍照存留。结果筛查检出角膜塑型者181例，ICL植入者7例。结论检眼镜彻照法可准确检出角膜塑型眼和ICL植入眼，操作便捷高效，适用于招收飞行学员等军事人员的群体性医学筛查。

ObjectiveTo introduce the effectiveness of the direct ophthalmoscope transillumination method for the screening identification of the eyes after orthokeratology and refractive corrected eye after posterior chamber ICL implantation (ICL implanted eye) and to analyze the mechanism of this technology.MethodsHandheld ophthalmoscope was used to transilluminate positive and the side in the pupil areas. In the background of reflective orange, the pupil areas were observed for the specific shadow occurrence. The shadow imaging was saved using the hole camera.ResultsThere were 181 cases of orthokeratology and 7 cases of ICL implant.ConclusionThe method of the ophthalmoscope transillumination is a thorough way to accurately detect orthokeratology and ICL implanted eyes. Because it is sensitive, specific, convenient and efficient, it is suitable for the population screening of student pilots and other military personnel.
