Abstract

A computer-aided method for the determination of colour fusion time (CFT) was developed. CFT indicates the acuity of the perception of monochromatic contours. CFT was determined in 36 patients with Parkinson's disease (PD) and compared with a group of 36 age- and sex-matched controls. Patients with PD generally had a shortened fusion time, especially for dark-green, light-blue and dark-red stimuli. The results give evidence to the hypothesis of a colour perception disorder in PD. The physiological and pathoanatomical basis of this phenomenon is unknown, but a functional deficit of cortical neurons may be a probable cause.

帕金森病的色彩知觉障碍。
提出了一种计算机辅助测定颜色融合时间(CFT)的方法。CFT表示对单色轮廓的感知的敏锐度。在36名帕金森病患者(PD)中测定CFT,并与36名年龄和性别匹配的对照组进行比较。PD患者融合时间普遍较短,尤其是对墨绿色、浅蓝色和暗红色刺激。研究结果为PD患者存在色彩感知障碍的假说提供了证据。这种现象的生理和病理解剖基础尚不清楚,但皮质神经元的功能缺陷可能是一个可能的原因。
