数字化随机点立体图在招飞体检中的应用

目的 探讨数字化随机点立体图在我国招飞体检中的实用价值.方法 应用数字化随机点立体图对861例视力及眼位正常的招飞体检受试者进行立体视锐度检查,对于立体视觉显著异常(立体视锐度≥800")者进一步进行Titmus立体镜检查及隐斜度数测定.结果 立体盲筛查图未通过者1例,占受检者总数的0.12%;立体视锐度800"者为4例,占0.46%;立体视锐度400"为7例,占0.81%;立体视锐度200"为4例,占0.46%,立体视锐度100"为9例,占1.05%;立体视锐度60"为76例,占8.83%;立体视锐度≤40"为760例,占88.27%.立体视锐度≥800"的5例中,4例为显性外斜视.结论 数字化随机点立体图没有任何单眼线索,能精准地进行立体视锐度定量测定,使用快捷简便,具有可操作性,在招飞体检工作中有重要实用价值.

Application of digital random-dot stereogram in the physical examination of pilot recruitment

Objective To find out the practicability of the digital random-dot stereogram (RDS) in the primary physical examination for naval air-force recruiting. Methods The stereo-acuity of 861 cases which with normal visual acuity was measured by digital RDS in the primary examination for naval air-force recruiting. Titmus test and heterophoria dimensionality measurement were taken for those who were with significant abnormal stereovision (stereo-acuity≥800"). The time limit for each subject is 1.5 min. Results One subject (0.12% of total) failed in recognizing the large visual field stereo-blindness screening plate. As to the stereo-acuity values for correctly recognizing the screening plate, 4 subjects (0.46%) were at 800", 7 (0.81%) were at 400", 4 (0.46%) were at 200", 9 (1.05%) were at 100", 76 (8.83%) were at 60" and 760 (88.27%) were less than 40". Among the 5 subjects whose stereo-acuity ≥ 800", 4 were diagnosis as exotropia. Conclusions The digital RDS could accurately and promptly measure the quantitative values of stereo-acuity dispense with any monocular cues. It shows effective applied value in the physical examination for pilots recruiting.
