Abstract

Time since death is a question of day to day challenge faced by teams of investigators during their course of investigations. Vitreous humour of eye being relatively stable, less susceptible than other body fluids to rapid chemical changes and contamination, easily accessible; thus it is suitable to estimate post-mortem interval (PMI).The dead bodies brought to the mortuary were used as material for collection of vitreous humour sample from the eyes of deceased. The vitreous analytes have been investigated to establish their correlation ship with PMI or time since death. The results of the present study suggest that the previously reported between eye differences for various vitreous biochemical constituents in the same pair of eyes are insignificant so far as forensic applications are concerned. Vitreous potassium and calcium is a useful biochemical marker for PMI estimations.
