[A method of standardizing the results of quantitative chemical investigations on material gained from vitrectomy (author's transl)].

In this study a method is described which allow conclusions to be drawn from the concentration of chemical substances in the material gained from vitrectomy in relation to the content of these substances in the whole vitreous body. In 16 pairs of human postmortem eyes enucleated 3-5 h after death one eye of each pair was subjected to vitrectomy under constant suction and infusion pressure and cutting rate; the duration of surgery varied (3-9 min) and in each fellow eye the whole vitreous body was removed. Comparison of the different concentrations of chemical substances in the samples showed that they could be correlated.
