Glucose 6-phosphate dehydrogenase deficiency both in red blood cells and lenses of the normal and cataractous native population of Cukurova, the southern part of Turkey. Part II.

A possible correlation between development of cataract and glucose 6-phosphate dehydrogenase (G6PD) deficiency in red blood cells and lenses was investigated. The distribution of cataract types in both G6PD-positive and G6PD-deficient patients, the incidence of G6PD deficiency in cortical cataract groups and the distribution of G6PD-deficient cases according to age were determined. The results showed that quite a high percentage of cortical cataractous patients had G6PD deficiency in both red blood cells and lenses.
