Abstract: Purpose: This study aims to explore glucose-6-phosphate dehydrogenase (G6PD) activity in diabetic retinopathy (DR) and its correlation with inflammatory factors, elucidating the regulatory role of G6PD in DR pathology. Methods: A total of 151 T2DM patients were divided into three groups: diabetes without retinopathy (DNR, n = 59), non-proliferative retinopathy (NPDR, n = 46) and proliferative retinopathy (PDR, n = 49). Plasma G6PD activity was measured by a Randox G6PD kit and compared between these groups. Then the G6PD activity was correlated with inflammatory cytokines and metabolic parameters in these patients. A STZ-induced diabetic rat model was established, G6PD activity was validated by western blot and immunofluorescence staining in the retina of this model. Results: Plasma G6PD activity decreased in the order of DNR, NPDR and PDR groups (P
