摘　　要：目的比较3种隐斜视检查方法，从而验证飞行员特殊视觉功能检查仪隐斜视检查结果的准确性。方法横断面研究。用飞行员特殊视觉检查仪和同视机、马氏杆隐斜计按操作规定对50名男性青年分别进行隐斜视检查．对3种仪器所测得的结果进行单因素方差分析．对主导眼与非主导眼所测得的结果进行配对t检验。结果①马氏杆与同视机检查结果中内隐斜最多，分别占38％、34％，单纯上隐斜最少，分别占2％、4％。检查仪则内隐斜合并上隐斜最多，占36％，正位眼最少，占4％。②3种仪器测得的内隐斜量为马氏杆〉检查仪〉同视机，三者之间差异有统计学意义（F=3．18，P〈0．05）。马氏杆与同视机之间差异有统计学意义（P〈0．05），但马氏杆与检查仪，以及检查仪与同视机之间差异无统计学意义（P〉0．05）。3种仪器测得的外隐斜量马氏杆〉同视机〉检查仪，三者之间差异均无统计学意义（F=0．83，P〉0．05）。3种仪器测得的上隐斜量检查仪〉马氏杆〉同视机。三者之间差异有统计学意义（F=6．34，P〈0．05）。同视机与检查仪、马氏杆之间差异有统计学意义（P〈0．05）。检查仪与马氏杆之间差异无统计学意义（P〉0．05）。⑧主导眼所测得的内隐斜、外隐斜、上隐斜量均大于非主导眼，但仅马氏杆所测得的内隐斜量双眼间差异有统计学意义（t=2．74，P〈0．01），余差异无统计学意义。结论3种检查方法之间所测结果存在一定差异，但检查仪与马氏杆测量的内、外、上隐斜均无差异。Objective to verily the accuracy ot the results ol special visual measurement instruments for heterphoric testing. Methods In this cross-sectional study, fifty healthy students served as subjects. The degree of heterphoria was measured by a special visual measurement instrument, the Maddox rod and a synoptophore. A one-way ANOVA and paired t test were used to calculate the data. Results （1）The Maddox rod and synoptophore measured the highest amounts of esophoria, accounting for 38% and 34%; hyperphoria was the least, accounting for 2% and 4%. Measurements with the special visual measurement instrument found the highest amounts of esophoria plus hyperphoria, accounting for 36%; orthophoria was found the least, accounting for 4%. （2）Esophoria values measured in order from the most to the least were the Maddox rod, measurement instrument and synoptophore （F=3.18, P〈0.05）. There was a significant difference between the Maddox rod and synoptophore （P〈0.05）, but there were no significant differences between the Maddox rod and measurement instrument and the measurement instrument and the synoptophore （P〉0.05）. Exophoria values measured from high to low were the Maddox, synoptophore and inspection instrument. There were no significant differences among the three methods （F=0.83, P〉0.05）. Hyperphofia values measured from high to low were the measurement instrument, Maddox rod and synoptophore （F=6.34, P〈0.05）. There were significant differences between the measurement instrument and synoptophore and the Maddox rod and synoptophore （P〈O.05）, but there was no significant difference between the measurement instrument and Maddox rod （P〉0.05）. （3）The dominant eye＇s value was higher than the nondominant eye＇s in esophoria, exophoria and hyperphoria, but only the Maddox rod measured a significant difference in esophoria （t=2.74, P〈0.01）. Conclusion There were differences in the degree of heterphoria measured by the three instruments, but there was no significant dif
