Remarks on the aqueous humor/plasma ratios for amino acids and related compounds in patients with various chronic ocular disorders.

The concentration of 19 amino acids and related compounds was simultaneuosly determined by means of ion exchange chromatography in the aqueous humour (Caq) and blood plasma (Cpl) of 40 patients with various chronic ocular disorders. The physiological aspects will be published elsewhere. It is of interest to note that very few significant differences have been found between the Caq/Cpl ratios for the groups into which the material could be clinically divided. This enables the conclusion to be drawn that determination of Caq/Cpl for amino acids and related compounds are not of diagnostic importance in the chronic ocular disorders which were studied.
