[Study of the composition of aqueous humor in normal subjects by means of automatic analytical technics].

Five new constituents in the aqueous humour were measured as part of a study on the constitution of the aqueous in normal subjects; urea, glucose, phosphorus, calcium and the carbonates and bicarbonates representing the alkaline reserve. Each of these constituents were measured by an automatic method using the Technicon auto-analyser, a similar sample of aqueous humour serving in some cases for simultaneous measurement of several constituents. The principles of the reaction, the Manifold used and the results obtained are reported for each of these. The latter were studied more particularly as a function of age on the one part and also a function of the serum levels of the same constituent. This simultaneous study establishes a relationship between the aqueous humor and the plasma which is compared with preceding reports in the literature and with results obtained more often in animals. Several important physiological and physiopathological considerations arise from these findings.
