Relationship between pilots' physiological data of anterior eye segments and flying time

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 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 (χ2=0.013, P>0.05). Pilots in 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. Key words: Refraction, ocular; Myopia; Anterior chamber; Corneal; Pilots
