Aqueous Humor Levels of Vascular Endothelial Growth Factor in Retinitis Pigmentosa

Abstract

In patients with RP, the concentration of VEGF-A in aqueous humors is lower than in non-RP subjects. The lack of angiogenic actions attributed to VEGF-A may explain some of the clinical manifestations of this disease, such as narrowing and fibrotic degeneration of retinal blood vessels.
