Popis: Purpose: To investigate aqueous humor (AH) and serum levels of brain-derived neurotrophic factor (BDNF) in non-proliferative diabetic retinopathy (NPDR) patients with diabetic macular edema (DME). Methods: The prospective study consists of 20 patients with DME NPDR, 20 patients with no-DME NPDR, and 20 healthy control subjects. Serum and AH samples were obtained during cataract surgery and intravitreal injection. Serum and AH levels of BDNF were measured by enzyme-linked immunosorbent assay. Results: The mean serum levels of BDNF were lower in both NPDR groups compared to the control group (DME NPDR group, p = 0.015; no-DME NPDR group, p = 0.024). Furthermore, the mean serum level of BDNF was lower in the DME NPDR group compared to the no-DME NPDR group ( p = 0.041). The mean AH levels of BDNF were significantly reduced in both NPDR groups compared to the control group (DME NPDR group, p Conclusion: Serum and AH levels of BDNF were reduced in NPDR patients with DME than without DME.
