目的追踪观察低常远视力飞行学员远视力变化趋势,为现行招飞体检标准的修订提供客观依据.方法选择招飞时0.8≤远视力＜1.0的飞行学员共137人为观察组;同期招飞时远视力≥1.0的飞行学员134人为对照组;分别复查双眼散瞳前后远视力,采用配对秩和检验、x2检验进行组内不同时间远视力的比较及组间比较.结果 ①1年后观察组远视力散瞳前后达标率分别为95.62%和98.18%,对照组为94.78%和97.76%;散瞳后最低远视力两组分别为0.6和0.7.⑦两组远视力在招飞时、散瞳前和散瞳后呈逐步提高趋势,差异有统计学意义(Z=230.72、12.76,P＜0.01).③复查时两组远视力均较招飞时提高,散瞳后尤为明显.④两组均存在不同程度的睫状肌调节痉挛,观察组更为显著.结论两组远视力绝大多数都符合招飞体检标准;调查阶段两组远视力均以稳定和上升趋势为主.

Objective To figure out the change tendency of flying cadet's subnormal distant vision based on one year follow-up study and to provide objective reference to the standards of physical examination for pilot recruitment.Methods One hundred and thirty-seven flying cadets, who had the subnormal distant vision in the range from 0.8 to 1.0 (include 0.8) that determined in physical examination of recruitment, were chosen as study group while other 134 homo-session flying cadets with 1.0 or better distant vision were randomly selected as control group.The distant vision of both groups was respectively rechecked under ante- and post-mydriasis states 1 year after enrollment.Results were statistically compared between states and between groups by matched-pairs rank test.Results ① Most cadets of study group remained stable distant vision according to 1 year later recheck and respectively 95.62% and 98.18% cadets, corresponding to ante- and post-mydriasis states, kept up to standard, comparing to 94.78% and 97.76% in control group.There were only few cadets in 2groups had their distant vision declined after 1 year and there was no significant difference between groups.The worst case was the going down to 0.6 and 0.7 post mydriasis vision respectively in study and control group.② Comparing to 1 year ago, both groups showed gradually improved distant vision both for with and without mydriasis and significance was found between groups (Z= 230.72, 12.76,P＜0.01).③ The distant vision of 2 groups showed significant increase under both ante- and postmydriasis state comparing to that of one year before, especially for the post-mydriasis state.④ The episode of ciliary muscle cyclospasm was appeared in various degrees in both groups.Conclusions Most of flying cadets in two groups keep their distant vision in stable improvement and match exam standard according to 1 year follow-up.Since ciliary muscle cyclospasm is common in flying cadets the oriented education of eye protection should be strengthened.
