Abstract:
Objective To observe the relationship between pilots' physiological data of anterior eye segments and flying time in order to provide a reference basis for better ophthalmological health care.Methods The ophthalmological data of the fighter pilots who were in the physical examination for transformation in General Hospital of Air Force or in annual examination but hospitalized due to non-ophthalmological reasons.Pilots were divided into ＜30 yr group (n=132) and ≥ 30 yr group (n=28).They were also divided into ＜1 000 h group (n=137) and ＞1 000 h group (n=23).Statistical analysis was done with SPSS 19.0 software.Results Pilots of different age groups had no statistic differences in visual acuity,axial length and mean corneal curvature (P＞0.05).The ratio of astigmatism with the rule and astigmatism against the rule between age groups also showed insignificant difference (x2 =0.013,P＞0.05).Pilots in ＜30 yr group had bigger spherical equivalent degree (t'=2.074,P＜0.05).The visual acuity,spherical equivalent degree,type of astigmatism,axial length,anterior chamber depth and mean corneal curvature were found no statistical difference between two age groups.No correlation existed between axial length in anterior chamber depth for the pilot in same group.A weak positive relationship was observed between visual acuity and spherical equivalent degree of the pilots in ＜30 yr group (r=0.287,P＜0.01) but in ≥ 30 yr group (P＞0.05).Axial length negatively correlated to mean corneal curvature in all pilots (r=-0.813).Conclusions Pilots' physiological data of anterior eye segments are mainly correlated with age but with flying time.
