Cataracts Resulting from a Deficiency of Phenylalanine in the Rat.

Abstract
The lenticular changes observed to result from phenylalanine-deficiency in the rat were diffuse haziness, opacity of the star, progressive separation of the fibers, granular changes in the epithelial layer and the development of dense central cataracts. Only the more superficial changes in the lenses were reversed by adding dl-phenylalanine to the diet.
