There is an enormous literature on vitreous biochemistry, much of it less than satisfactory:- try James, R. A., P. A. Hoadley, et al. (1997). “Determination of postmortem interval by sampling vitreous humour.” American Journal of Forensic Medicine & Pathology 18(2): 158-62. Pounder, D. J., D. O. Carson, et al. (1998). “Electrolyte concentration differences between left and right vitreous humor samples.” Journal of Forensic Sciences 43(3): 604-7. or even Swift, P. G., E. Worthy, et al. (1974). “Biochemical state of the vitreous humour of infants at necropsy.” Archives of Disease in Childhood 49(9): 680-5.
