Oxidative stress intensity in lens and aqueous depending on age-related cataract type and brunescense

Cataract formation represents a serious problem in the elderly, and has a large impact on healthcare budget. The oxidative stress form and intensity might determine the cataract type and pigmentation, making efforts in the cataract prevention challenge more complex. This is a retrospective cross-sectional review of 80 samples of aqueous humor and lens corticonuclear blocks. Aqueous samples were analyzed by the method of antioxidant activity estimation (%iMDA), while lipid peroxides (LP) and total sulfhydryl groups (TSH) were determined in lenses. Mixed and brunescent cataracts have statistically significant lower values of antioxidative %iMDA and TSH (p
