[Advancement in the study on electrophysiology of color vision and its applicability in forensic medicine].
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.
