三种立体视觉检查方法在招飞体检中的应用

目的 探讨3种不同立体视锐度检查方法在海军招飞体检中的应用价值.方法 274例视力正常的海军航空学院报考者根据眼位分为正常组(242例)和斜视组(32例),应用Titmus 立体图、TNO立体视觉检查图及数字化立体视觉检查图(颜氏图)3种方法进行立体视锐度测定.结果 3种方法检测所得正常组中立体视觉正常者(立体视锐度≤60″)所占百分率分别为Titmus 98.34%,TNO92.98%,颜氏图97.52%.Titmus方法所得结果与颜氏图检测结果比较差异无统计学意义,二者分别与TNO检测结果比较,差异均有统计学意义(Z=-3.272、-3.314,P＜0.05).斜视组3种方法检测所得立体视觉正常者所占百分率分别为Titmus 90.63%,TNO 71.88%,颜氏图75.00%,TNO检测与颜氏图检测结果比较,差异无统计学意义,二者分别与Titmus检测结果比较,差异均有统计学意义(Z=-2.825、-2.428,P＜0.05).结论 颜氏图检测结合Titmus立体图检测应用于招飞体检可以获得较为理想的立体视觉检查结果.Abstract：Objective To evaluate the practicability of three stereovision tests in the stereoacuity examination for Navy aviator recruiting.Methods The stereoacuity was measured both for the group of normal position of eye (242 subjects) and strabismus group (32 subjects) by Titmus,TNO test for stereoscopic vision (TNO) and Yan's Digital Stereovision tests.Results The percentage of normal stereovision (stereoacuity≤60″) in normal group was respectively 98.34% by Titmus, 92.98% by TNO and 97.52% by Yan's.There was no significant difference between the measurements of Titmus and Yan's test but the significance was found in TNO test compared with other teszs (Z=- 3.272、- 3.314, P＜ 0.05).In strabismus group, the percentage of normal stereovision was respectively 90.63% by Titmus, 71.88% by TNO and 75.00% by Yan's.Testing by TNO or Yan's had no statistic difference but for the testing by Titmus (Z= -2.825、-2.428, P＜0.05).Conclusions The Yan's Digital Stereovision test combined with Titmus test could be appropriate to stereoacuity examination for pilot recruitment.
