Objective To investigate the serum transforming growth factor-β (TGF-β) levels in patients with diabetic retinopathy  (DR). Methods Seventy-two patients with diabetes were selected, including 15 patients with proliferative diabetic retinopathy (PDR group), 32 patients with non-proliferative diabetic retinopathy (NPDR group) and 25 patients with non-diabetic retinopathy group (NDR group). Besides, 45 healthy people were served as normal control group. The serum TGF-β levels were detected by ELISA. Results Serum TGF-β levels in groups with diabetes were significantly higher than that in normal control group (P<0.01). Serum TGF-β level in PDR group was significantly higher than those in NPDR group and NDR group (P<0.05). Conclusion Serum TGF-β level is associated with the severity of diabetic retinopathy.
