190名海军飞行员动态视力检测结果分析

Analysis of the kinetic visual acuity test results of 190 navy pilots

目的全面了解海军飞行员的动态视力(KVA)情况,为客观评价海军飞行员的视力水平提供依据。方法采用DS-3型KVA仪,视标运动速度为30 km/h,对2018年12月至2019年12月在海军特色医学中心体检的190名海军飞行员进行单、双眼的KVA检测;采用"卡片法"检测海军飞行员主视眼情况。结果所有受检飞行员静态视力均≥1.0,6.05%的单眼和4.74%的双眼KVA<1.0。不同年龄组海军飞行员的双眼(P=0.07)和单眼(P=0.16)KVA差异均无统计学意义。190名海军飞行员的左眼KVA略高于右眼(P=0.168),主视眼KVA略低于非主视眼(P=0.284),但差异均无统计学意义;单眼KVA明显低于双眼,差异有统计学意义(P<0.05)。结论在开展海军飞行员招飞体检和健康鉴定等体格检查工作中,除静态视力外,还应当开展KVA检测。受检海军飞行员的年龄对KVA无明显影响;单眼KVA明显低于双眼,左、右眼KVA水平均衡,且在KVA检测过程中未体现出主视眼优势。

Objective To provide a reliable basis for the objective evaluation of the kinetic visual acuity(KVA)of navy pilots through a comprehensive analysis of the KVA test results among 190 navy pilots.Methods We measured both the monocular and binocular KVA of 190 navy pilots at the Naval Medical Center with a DS-3 dynamic vision apparatus.The vision target velocity was set at 30 km/h.The hole-in-the card was also performed to examine the dominant eyes of the navy pilots.Results The static visual acuity of all pilots tested was≥1.0,but 6.05% of the monocular KVA and 4.74% of the binocular KVA were<1.0.There were no statistically significant differences in the binocular KVA(P=0.07)and monocular KVA(P=0.16)of the navy pilots of different age groups.The KVA of the left eyes was slightly higher than that those of the right eyes,but without statistical significance(P=0.168).The KVA of the dominant eyes were slightly lower than the non-dominant eyes,but without statistical significance either(P=0.284).The monocular KVA was significantly lower than the binocular KVA(P<0.05).Conclusion In the health exam for navy pilot recruitment and pilot health assessment,it is advisable for candidates/pilots to take a KVA test in addition to a static visual acuity test.The age of the examined navy pilots has no significant impact on their KVA.The monocular KVA is significantly lower than the binocular KVA.The KVA of the left eyes and the right eyes is relatively balanced,and the advantage of dominant eyes is not reflected in the KVA test.
