摘　　要：目的分析招飞学员群体中视力与对比敏感度(contrast sensitivity,CS)的关系,并探讨在招飞选拔体检工作中应用对比敏感度检查的可能性。方法检查招飞学员对比敏感度函数(contrast sensitivity function,CSF)值,将符合纳入标准的98例样本按视力1.0为标准分为两组,比较4种空间频率(3、6、12、18 cpd)、3种状态(明视、暗视、暗视+眩光)的CSF值。结果两组在不同状态、不同空间频率的CSF值差异均无统计学意义(P>0.05);在各空间频率下,明视与暗视状态下的CSF值差异有统计学意义(P<0.05),暗视与暗视+眩光状态下的CSF值差异均无统计学意义(P>0.05)。结论部分招飞学员视力表检查结果正常,而CSF值出现异常,特别是在高空间频率段的明暗分辨率下降。现行招飞选拔体检标准无法筛选这些学员,可以尝试增加中高空间频率下暗视的CSF值作为招飞体检的指标。Objective To analyze the relationship between visual acuity and contrast sensitivity（CS） in flying cadets,and to discuss the possibility of applying CS test in pilot selection.Methods Ninety-eight samples who met the inclusion criteria were divided into two groups according to their visual acuity（distant vision≥1.0 or 0.8≤distant vision1.0）.The contrast sensitivity function（CSF） values of the different groups checked under 4 spatial frequencies（3,6,12 and 18 cpd） and 3 statuses（photopic,scotopic,scotopic plus glare） were compared.Results There were no significant differences in CSF values between the two groups under different spatial frequency or light conditions（P0.05）.There were significant differences in CSF values between the photopic group and scotopic group under different spatial frequency（P0.05）,but no significant differences in CSF values were found between the scotopic group and scotopic plus glare group（P0.05）.Conclusion Some of the flying cadets may have normal visual acuity and abnormal CSF values,especially under the middle to high spatial frequency.Since the current physical examination standard of pilot selection fails in this aspect,we may select the CSF values at mid-high spatial frequency and under scotopic conditions as an index.
