目的:比较不同职业特勤人员屈光不正的检出率，为相关防治工作提供依据。方法:将2 394名特勤人员按照职业不同分为飞行员、空中战勤人员、潜艇艇员和潜水员、舰员，比较不同职业特勤人员屈光不正的检出率。结果:2 394名特勤人员屈光不正的检出率为8.98%(215/2 394)，空勤人员检出率(4.37%)低于海勤人员(31.68%)，差异有统计学意义(n P<0.01)；其中舰员屈光不正的检出率最高(37.50%)，飞行员的检出率最低(1.85%)，与空中战勤人员、潜艇艇员和潜水员的差异均有统计学意义(n P<0.05或n P<0.01)。n 结论:海勤人员屈光不正的发生率不容乐观，需要进一步加强海勤人员的视力保健。“,”Objective:To compare the detection rates of ametropia in special duty personnel of different occupations, so as to provide a reference for prevention and treatment.Methods:A total of 2 394 special duty personnel were divided into 4 groups according to their occupations: pilot, air combat service personnel, submariner and diver, and warship crewmember. Then the detection rates of ametropia among the groups were analyzed.Results:The detection rate of ametropia in 2 394 special duty personnel was 8.98% (215/2 394). The detection rate of ametropia in the air service personnel (4.37%) was lower than that in the sea service personnel (31.68%). The difference was statistically significant (n P<0.01). The incidence of ametropia in the warship crewmembers was the highest (37.50%), while that of the pilots was the lowest (1.85%). The differences between them and those of the air combat service personnel and submariners and divers were statistically significant (n P<0.05, orn P<0.01).n Conclusion:The incidence of ametropia in sea service personnel is not optimistic, and it is necessary to attach greater importance to vision care of sea service personnel.
