VEGFA and retinal disorder: In a mice model, it was shown that Vitamins C, E, and omega-3 fatty acid supplementation improved retinal vascularization in phase 1 oxygen-induced retinopathy model, and the administration of dipeptide arginyl-glutamine in phase 2 diminished retinal vasoproliferation by reducing vascular endothelial growth factor (VEGF) expression, thereby suggesting that AA deprivation might be considered to contribute to oxygen-induced retinopathy [4–6].
