方法：南航2012年度广东地区招飞上站眼科第一轮通过650例学生，卡孔法判断被检者主视眼眼别，将便携式隐斜计分别放置在主视眼(主视眼组)与非主视眼(非主视眼组)前测量隐斜值，用Von Graefe法测量值作为对照，外隐斜为负值、内隐斜为正值，垂直隐斜取绝对值。分别对主视眼组与非主视眼组、主视眼与Von Graefe法组、非主视眼组与Von Graefe法组隐斜值进行统计学分析。

结果：Von Graefe法组外隐斜平均为-2.21±0.35^△，内隐斜平均为+3.87±1.20^△，上隐斜为+0.44±0.12^△； 主视眼组外隐斜平均为-2.68±0.55^△，内隐斜平均为+6.22±2.55^△，上隐斜为+0.46±0.15^△； 非主视眼组外隐斜平均为-2.16±0.40^△，内隐斜平均为+3.22±1.65^△，上隐斜为+0.45±0.14^△。水平隐斜(外隐斜和内隐斜)：主视眼组与非主视眼组有统计学差异(P<0.05)，主视眼组与Von Graefe法组有统计学差异(P<0.05)，非主视眼组与Von Graefe法组无统计学差异(P>0.05)； 垂直隐斜：Von Graefe法组与主视眼组、非主视眼组无明显统计学差异(P>0.05)。

结论：民航招飞隐斜检查时便携式隐斜计放置在被检者非主视眼前结果更为可靠。

METHODS:Totally 650 candidates had passed the first round of ophthalmology check of China Southern 2012 Annual civil aviation cadet in Guangdong province. We picked out their dominant eyes by card-hole method, then respectively placed in front of the dominant eye(the dominant eye group)and non-dominant eye(non-dominant eye group)to measure phoria value. Von Graefe measurement value was as a control, exophoria was negative, esophoria was positive, vertical phoria was absolute value. Chi-square test was applied to analyze the phoria values respectively in the phoria group between dominant eye group and non-dominant eye group, dominant eye and Von Graefe law group, non-dominant eye group and Von Graefe law group.

RESULTS: Von Graefe group: average exophoria value was -2.21±0.35^△, average esophoria value was +3.87±1.20^△, hyperphoria value was +0.44±0.12^△. Average exophoria value of dominant eye group was -2.68±0.55^△, average esophoria value was +6.22±2.55^△, average hyperphoria value was +0.46±0.15^△; average exophoria value of non-dominant eye group was -2.16±0.40^△, average esophoria value was +3.22±1.65^△, hyperphoria value was +0.45±0.14^△. As for horizontal heterophoria(exophoria and esophoria), there was significant difference between dominant eye group and non-dominant eye group(P<0.05), dominant eye group and Von Graefe group(P<0.05), and there was non-significant difference between non-dominant eye group and Von Graefe group(P>0.05); As for vertical heterophoria, there was non-significant difference among the Von Graefe group, the dominant eye group and non-dominant eye groups(P>0.05).

CONCLUSION:The results are more reliable when portable phoria meter placed in front of dominant eye during the phoria check for civil aviation cadet.
