With increasing time, post-mortem vitreous sodium and glucose concentrations diminish, whereas urea and magnesium rise. Vitreous magnesium levels are age related. Chemical analysis of vitreous humour is thus a valid adjunct to the post-mortem examination and may be important in the study of unexpected deaths in infancy. %U https://adc.bmj.com/content/archdischild/49/9/680.full.pdf
