ANTIOXIDANT ACTIVITY OF PLASMA FROM SUBJECTS WITH AND WITHOUT SENILE CATARACT

The relationship between overall plasma antioxidant activity and senil e cataract was examined in 148 subjects aged 37-90 years. Antioxidant activity of plasma from 52 control and 96 patients with senile catarac t was determined by a method which measures the capacity of plasma to inhibit auto oxidation of bovine brain homogenate. In contrast to prev ious studies which demonstrated a relationship between decreased level s of antioxidant components in blood and the occurrence of lens opacit ies, the present study does not show any significant difference betwee n subjects with and without senile cataract.
