Relative contents of sodium, potassium, and dry matter in diabetic cataractous lenses.
Cataractous lenses from diabetic patients were pre-operatively divided into 3 groups according to the biomicroscopical appearance of the lenses and biochemical analyses of CNa+, CK+, and dry matter were performed. 1) Immature cataractous lenses without anterior capsular/subcapsular opacity (ac-sco): (N=4) CNa+ = 35 meq/kg lens water, CK+ = 164 meq/kg lens water, dry matter 24%. 2) Immature cataractous lenses with ac-sco: (N=12) CNa+ = 151 meq/kg lens water, CK+ = 62 meq/kg lens water, dry matter 33%. 3) Totally opaque lens: (N=1) CNa+ = 185 meq/kg lens water, CK+ = 12 meq/kg lens water, dry matter 19%. The concentrations of sodium, potassium, and dry matter were equal to the findings in senile non diabetic cataractous lenses.
