[Glutathione content of the lens in various forms of cataract].

Both the electrolyte ratio (K greater than Na) and high glutathione content of the lenses are generally undisturbed in the brunescent nuclear cataract (cataracta brunescens), the primary grey nuclear cataract, and the supranuclear cataract (senile cortical cataract). The electrolyte ratio (Na greater than K) and greatly decreased glutathione content are also grossly pathological in the subcapsular cataract (cataracta complicata, posterior subcapsular cataract), especially in connection with a secondary grey nuclear cataract, the mature cataract (cataracta matura), and the intumescent cataract. Alteration of the electrolyte concentrations and the glutathione content may be the results of physical, anatomical, and various metabolic disorders.
