Abstract:
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.
