The eyes have it!


by blogger mem

Scientists at the University of Santiago de Compostela have developed software that can more accurately determine the Post-Mortem Interval (PMI) using vitreous humor from the eyes of cadavers. They measure the levels of potassium, urea and a DNA metabolite, hypoxantine. The numbers are then crunched in a program they developed to calculate the PMI. If the results are accurate, it could be very useful to forensic pathologists

“The equations we have developed now make it possible for us to estimate the PMI more precisely than before, and provide a useful and accessible tool to forensic pathologists that is easy to use.

The precision and usefulness of these two models have been confirmed by chemical analysis in more than 200 vitreous humour samples. The doctor and the two mathematicians who have performed the study have verified that the SVM method offers more precise data.”
