Do Not Turn a Blind Eye on Forensic Biochemistry: Using Vitreous Electrolytes to Reveal Renal Insufficiency as Cause of Death.

In both medical and forensic autopsy, the kidneys may be overlooked grossly and histologically. As both acute and chronic kidney dysfunction have major implications on morbidity and mortality, it is essential to consider the kidneys as a pathologic source for both immediate and proximate cause of death. For decades, vitreous humor has been used as a measure of postmortem electrolyte analysis to help understand ionic disturbances carried over from the antemortem period. Renal insufficiency from both acute and chronic kidney dysfunction can be ascertained from vitreous investigations and should be a consideration for cause of death. Here, we present 4 cases in which vitreous analysis was used to determine the cause of death. In highlighting these cases, we support the use of biochemical testing in autopsy while demonstrating how it can help elucidate an often overlooked means of mortality. Importantly, it can help with the formulation of clinicopathologic correlations between antemortem and postmortem findings.
