摘　　要：目的：探讨正常视力飞行员隐斜度数的临床意义。方法：以环形视标视力表，测定697名飞行员视力。采用STEVEN旋转棱镜作6m距离水平及垂直隐斜检查。常规小瞳孔眼底检查。结果：正位43人（6.2％）；隐斜654人（93.8％），其中外隐斜73人（11.1％），内隐斜58人（8.9％），上隐斜109人（16.7％），外隐斜合并上隐斜209人（32.0％），内隐斜合并上隐斜205人（31.3％）。外隐斜0°～4°者279人（占外隐斜人数98.6％），内隐斜0°～4°者249人（占内隐斜人数94.7％）。结论：本调查表明，在正常视力飞行员中，患隐斜者高达93.8％。上隐斜人数〉外隐斜人数〉内隐斜人数。内隐斜合并上隐斜与外隐斜合并上隐斜人数基本相同。内外隐斜度数主要分布0°～4°，上隐斜分布在2°之内。以上调查结果可以为招飞工作及制定眼科隐斜标准规定提供参考。Objective： To investigate clinical significance of heterophoria dimensionality in pilots with normal visual acuity. Methods： The vision of 679 pilots were examined by circular optical visual chart, and the horizontal and vertical heterophoria, by the STEVEN rotary pris in 6 meters distance, small pupils and fundus, by routine method. Results： Among investigated pilots, 43 pilots （6.2%） were emmetropia; 654 pilots （93.8%） were heterophoria. Among heterophoria cases, 73 （11.1% ） cases were exophoria, and 58 （8.9%）, e.sophoria, and 109 （16.7%）, hyperphoria, and 209 （32.0%）, exophoria combined with hyperphoria, and 205 （31.3%）, e.sophoria combined with hyperphofia. The pilots of exophofia in 0-4 degrees were 279, accounted for 98.6% in total exophoria cases, and those of esophoria in 0-4 degrees, 249, accounted for 94.7 % in total esophoria cascs. Conclusion： The proportion of heterophoria cases in pilots with normal vision is 93.8% very high. Exophoria and esophiria mainly occurs in 0 - 4 degrees, and hyperphoria occurs in 2 degrees. The results can provide referencs for stipulating the criteria of heterophoria and .selecting qualitied pilots.
