Vitreous humor chemistry in deaths associated with rapid chilling and prolonged freshwater immersion.

Vitreous humor chemistry studies were performed on 13 air crash victims who had remained immersed in near-freezing fresh water for seven to eight days. Glucose concentrations were observed to be higher than those in a comparison group of autopsied cases with prolonged postmortem intervals, suggesting that rapid chilling inhibited glycolysis. Evidence of dilution of vitreous humor electrolytes was also noted. After correction for the apparent degree of dilution, the potassium concentrations were found to fall within a narrow range.
