Diabetic retinopathy and vascular endothelial growth factor

Recently, I read with interest the article of Javanmard et al., who reported that the aqueous level of vascular endothelial growth factor (VEGF) in non‑proliferative diabetic retinopathy (NPDR) was not different compare to non‑diabetic patients, while soluble form of VEGF receptor‑1 (sVEGFR‑1) was lower in NPDR than non‑diabetic subjects.
