飞行员特殊视觉检查仪立体视觉功能检查的探讨

Investigation of applying special vision inspection instrument on pilot＇s stereo vision function

目的 检验飞行员特殊视觉检查仪中立体视觉功能检查的精度和准确性,探索其在飞行员医学鉴定中应用的可行性.方法 选取52名健康男性青年为受试对象,在同一环境下,由同一检查者分别用飞行员特殊视觉检查仪、金氏双眼立体视觉检查图和Titmus检查图对每名受试者进行立体视觉功能检查,记录最小识别图形的秒角.结果 飞行员特殊视觉检查仪的合格人数为49名（94.23%）,Titmus检查图的合格人数为50名（96.15%）,金氏双眼立体视觉检查图的合格人数为45名（86.54%）.经统计学分析,飞行员特殊视觉检查仪与Titmus检查图及金氏立体视觉检查图无统计学差异,Titmus检查图与金氏立体视觉检查图之间也无统计学差异（x2=0.00、1.77、1.77,P＞0.05）.结论 飞行员特殊视觉检查仪中立体视觉功能检查能准确、可靠地定量测定立体视锐度.

Objective To explore the accuracy of stereo vision inspection measured by special vision inspection instrument and to evaluate the feasibility of applying the instrument for pilot＇s physical examination. Methods Fifty-two healthy adults served as subject. Their stereo vision was respectively inspected by a special designed stereo vision inspection instrument, Jin＇s binocular vision test atlas and Titmus test atlas. The minimum are-second was recorded. Results There were 49subjects （94.23 %） passed the instrument inspection comparing to 50 （96.15 % ） by Titmus test atlas and 45 （86.54 %） by Jin＇s. There was no significant differences among these three inspection methods （x2 = 0. 00, 1.77, 1.77, P ＞ 0. 05）. Conclusions The special vision inspection instrument can accurately, reliably and quantificationally measure pilot＇s stereo vision function.
