Determination of the time since death in the early postmortem period is one of the most critical issues to be faced by criminal investigators. One of the techniques is the evaluation of the pupil pharmacological reactivity. In the present work, we aim at identifying whether an objective and single method, based on pharmacological pupil reaction, is feasible or not. Between 2002 and 2003 calendar years, we observed 309 bodies, whose eyes have been each instilled apart, within 26 hours since death, with either a myotic substance or a mydriatic solution. Our results show that the real effectiveness of pupil pharmacological reactivity as method for assessing the time since death in early postmortem period is not only questionable but even highly misleading if not replaced by alternative objective physiological tests and appropriate professional judgments by the investigators.
确定死后早期的死亡时间是刑事调查人员面临的最关键问题之一。其中一项技术是评估瞳孔的药理反应性。在本研究中，我们旨在确定基于药理瞳孔反应的客观单一方法是否可行。在2002年至2003年期间，我们观察了309具尸体，在死后26小时内，每只眼睛分别滴入缩瞳物质或散瞳溶液。我们的结果表明，瞳孔药理反应性作为评估死后早期死亡时间的方法，其实际有效性不仅值得怀疑，而且如果没有其他客观生理测试和调查人员适当的专业判断作为替代，甚至会产生高度误导性。
