What does vitreous chemistry analyze?

Vitreous chemistry focuses on analyzing the vitreous humor, which is the clear gel-like substance located in the posterior segment of the eye, filling the space between the lens and the retina. This analysis can provide valuable information in forensic investigations, particularly in determining the post-mortem interval, as the chemical composition of the vitreous humor changes after death.

By examining the levels of various substances such as electrolytes, glucose, and other metabolites within the vitreous humor, forensic scientists can infer the time since death or other physiological conditions. This makes vitreous humor analysis a useful tool in forensic pathology, especially in cases where blood or other bodily fluids are not available or suitable for analysis.

In contrast, the other options pertain to different areas of forensic analysis. Blood serum composition and acidity levels in tissues are important but do not relate specifically to vitreous chemistry, while drug presence analysis typically focuses on various bodily fluids or tissues rather than the vitreous humor.
