title: Alteration in glutathione metabolism during cataract progression.
abstract: Human cataractous lenses obtained from eye relief camp showed decreased levels of sulphydryl and glutathione. Significant depletion in activities of glutathione reductase, glutathione peroxidase and glucose-6-phosphate dehydrogenase was also encountered. These findings indicated an impairment in glutathione metabolism of the mature cataractous lenses as compared to immature lenses, and oxidative stress could be considered as a primary event in this process.
