title: Serum tryptophan in humans with senile cataracts.
abstract: Serum free and total tryptophan levels have been measured in patients with cataracts and compared with the same levels in controls with clear lenses. No statistically significant differences have been demonstrated between the two groups of examined fasting subjects. Preliminary results seem to indicate that differences could be evident after L-tryptophan oral load.
