title: Vitamin metabolism and therapy in ophthalmology.
abstract: Vitamin deficiency states are important in the genesis of many ocular disorders. Deficiencies may be due to poor dietary intake, or to alterations in metabolism produced by some commonly prescribed medications or by certain diseases. Furthermore, some vitamins may exert important pharmacologic effects on the normal eye. The ocular effects of deficiencies and excesses of specific vitamins, and the therapeutic uses of each vitamin, are reviewed.
