Vascular endothelial growth factor-A (VEGF-A) in vitreous fluid of patients with proliferative diabetic retinopathy.

Abstract

VEGA-A concentration was measured in undiluted vitreous fluid samples were taken at the start of vitrectomy procedure from 9 new cases of proliferative diabetic retinopathy and 8 non-diabetic patients. A positive correlation was found between VEGF-A levels and blood sugar and HgbA1c levels of patients with proliferative diabetic retinopathy.
