摘要
色觉是视觉功能的重要组成部分。目前色觉的检查主要依靠主观检查方法,研究和探索色觉客观检查方法具有重要的临床意义和法医学价值。随着现代科学技术的日益进步,视觉电生理学检查方法已逐渐成为色觉临床诊断与研究的重要手段。视网膜电图(electroretinogram,ERG)可以对不同的锥细胞及色觉异常进行区分,不同颜色刺激所产生的视觉诱发电位(visual evoked potential,VEP)也有不同的形态特征。通过对不同视觉电生理学检测方法,尤其是视网膜电图、闪光诱发电位、图形诱发电位等在色觉研究方面的新进展等文献的复习表明,色觉电生理研究技术将为网膜功能、脑功能的法医临床学评定提供重要手段。
Color vision is a major component of vision function. Examination of color vision mostly relies on subjectivity at present. It is important to establish an objective method of color vision examination that would have particular clinical significance and forensic medicine value. With the development of new technology, the examination of visual electrophysiology has become a basic method of clinical diagnosis and investigation. Electroretinogram （ERG） could discriminate different cone cells and color abnormality. Visual evoked potential （VEP） generated characteristic negative wave after stimulation with different colors. Different visual electrophysiology detection methods were reviewed and in particular important new advancement of color vision research of ERG, F-VEP and P-VEP were introduced. The application prospect of color vision research in the clinical forensic medicine was also discussed. It is likely that color vision research study and visual electrophysiology will provide objective evaluation of retina and brain function.
