title: Vitreous potassium as a measure of the postmortem interval: an historical review and critical evaluation.
abstract: This is an historical review of the articles published in English on the use of vitreous potassium to determine the PMI. External factors which influence the validity of the test are sampling techniques, analytical instrumentation and environmental temperature during the PMI. Internal factors that are recognized at the present time which influence vitreous potassium are the age of the individual, the duration of the terminal episode and the presence or absence of nitrogen retention.
