The potential use of the eye temperature decrease in determining the time of death in the early postmortem period: studies in pigs.
The experiment was performed in pigs during which the postmortem body temperature was continuously measured. The study was focused on a period of time starting 0.5 hours after the animals' termination and consisted in computer recording of the cooling process of the eyeball (vitreous humor), orbit soft tissues, muscles, and the rectum. The experiment revealed the absence of a plateau phase of temperature decrease in eyeball and orbit soft tissues contrary to muscles and rectum, what demonstrates that temperature measurements in the eye could become an alternative method of determining the time of death during the initial phase of postmortem cooling. During this early postmortem period determination of the time of death based on measurements of the rectum or muscles temperatures due to existing plateau is not possible.
