Estimation of postmortem interval （PMI） plays a crucial role in forensic study and identification work. Because of the unique anatomy location, vitreous humor is considered to be used for estima- ting PMI, which has aroused interest among scholars, and some researches have been carried out. The detection techniques of vitreous humor are constantly developed and improved which have been gradually applied in forensic science, meanwhile, the study of PMI estimation using vitreous humor is updated rapidly. This paper reviews various techniques and instruments applied to vitreous humor detection, such as ion selective electrode, capillary ion analysis, spectroscopy, chromatography, nano-sensing technology, automatic biochemical analyser, flow cytometer, etc., as well as the related research progress on PMI estimation in recent years. In order to provide a research direction for scholars and promote a more accurate and efficient application in PMI estimation by vitreous humor analysis, some inner problems are also analysed in this paper.
死后间隔时间（PMI）的估计在法医学研究和鉴定工作中起着至关重要的作用。由于独特的解剖位置，玻璃体液被认为可用于估计PMI，这引起了学者们的兴趣，并已开展了一些研究。玻璃体液的检测技术不断发展和完善，已逐渐应用于法医学领域，同时，利用玻璃体液估计PMI的研究也在迅速更新。本文综述了应用于玻璃体液检测的各种技术和仪器，如离子选择性电极、毛细管离子分析、光谱学、色谱法、纳米传感技术、自动生化分析仪、流式细胞仪等，以及近年来PMI估计的相关研究进展。为了为学者提供研究方向，促进玻璃体液分析在PMI估计中更准确、高效地应用，本文还分析了一些内部问题。
