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.
色觉是视觉功能的一个主要组成部分。目前，色觉检查大多依赖于主观性。建立一种客观的色觉检查方法具有重要的临床意义和法医学价值。随着新技术的发展，视觉电生理检查已成为临床诊断和研究的基本方法。视网膜电图（ERG）可以区分不同的视锥细胞和颜色异常。视觉诱发电位（VEP）在不同颜色刺激后产生特征性负波。本文综述了不同的视觉电生理检测方法，特别介绍了ERG、F-VEP和P-VEP色觉研究的重要新进展。还讨论了色觉研究在临床法医学中的应用前景。色觉研究和视觉电生理很可能会为视网膜和脑功能提供客观评估。
