A bright pocket flashlight was directed into one eye for 10 seconds; the subject then closed the eyelids and reported the sequence of after-image colours observed. Lesions of the visual system which compromised bilateral central colour vision also reduced or abolished the `flight of colours'. This simple bedside test of each eye independently is of value in detecting mild defects of central vision.
将一个明亮的袖珍手电筒对准一只眼睛照射10秒钟;然后受试者闭上眼睛,并报告观察到的后像颜色顺序。损害双侧中心色觉的视觉系统病变也会减少或消除“颜色幻视”。这种对每只眼睛独立进行的简单床边检查,对于检测中心视力的轻度缺陷具有重要价值。
