Role of Glucose 6 Phosphate Dehydrogenase (G6PD) in Diabetic Cataract

Introduction: Diabetes mellitus and its complications are spreading with increased rate in Asian population especially in Pakistan. Uncontrolled diabetes can lead to different micro vascular complications. Cataract is one of the complications of diabetes which may lead to lens degenerative changes and visual impairment. G6PD plays a vital role in preventive measurements from cataract development in normal population.

Objectives: This Study was designed to estimate G6PD levels in diabetic without ocular manifestations & diabetic cataract population.

Methodology: This cross sectional comparative study was done at the Department of Biochemistry LUMHS Jamshoro in collaboration with the Diabetic clinic, Institute of Ophthalmology & Diagnostic Research Laboratory LUMHS Jamshoro. 100 diagnosed subjects of diabetes were selected by Non-Probability type of sample technique with consent of subjects and they were divided in to two groups Group A as control 50 diabetic subjects with out ocular manifestation while Group B as case study group contain 50 subjects of diabetes with cataract. The fasting blood glucose level was estimated by Hexokinase Method while G6PD level was measured by kit method on SD Biosensor while HbA1c(% ) was estimated by TTAB methodology. The data was statistically analyzed by SPSS 21.

Results: The mean level of G6PD in Group A was 15.63±2.45 u/Hb while in group B it was 9.01±3.11 u/G HB. This result finally concluded that there was significantly (<0.05) decline of G6PD diabetic cataract as compared with diabetic without cataract.

Conclusion: This study concluded that there was significant decline in G6PD level in diabetic cataract. It is also concluded that the estimation of G6PD level in diabetic population will be beneficial to take early preventive measurements against diabetic vascular complications.
