摘　　要：目的　研制一种由被试者持于手掌上自行操作的视觉神经行为功能测试仪 ,并观察其测试效果。方法　仪器采用单片微机控制的硬件结构 ,由受试者鉴别四个发光二极管的闪光频率 ,并做出按键反应 ,自动评定其视觉神经行为功能分数。结果　受试者昼夜不同时刻的测试实验 ,0 9∶ 0 0时的分数显著高于 2 0∶ 0 0时和 0 3∶ 0 0时的分数 (P<0 .0 1)。结论　该仪器能够敏感地检测出被试者视觉神经行为功能的变化 ,适合于各种工作现场的普及应用。Objective A visual neurobehavioral function test instrument which can be operated by subject is developed. The test results of this instrument are demonstrated by experiment. Methods The hardware structure of the instrument is controlled by a single chip microcomputer. After one of four LEDs flash frequencies is distinguished, the subject makes a response to press a corresponding key. The instrument automatically gives the score of visual neurobehavioral function. Results Through the experiment from day to light, we find that the score at 09∶00 is obviously higher than the score at 20∶00 and at 03∶00 ( P <0 01). Conclusions This instrument can sensitively detect the changes of the subject′s visual neurobehavioral function. It is especially suitable for popular using in various location.
