Serum tryptophan and cataract.
Total serum tryptophan concentrations were measured in 74 cataractous patients and 124 controls. No significant differences were observed in the mean values for the cataractous and normal subjects, 11.4 +/- 2.6 and 11.3 +/- 2.2 micrograms/ml respectively, or in the range of values, 7.4-17.1 and 7.3-17.4 micrograms/ml respectively. These results do not support previous reports that serum tryptophan is elevated in cataractous subjects.
