VEGF-A and its receptors VEGFR-1 and VEGFR-2 promote angiogenesis throughout the body and represent the primary mediators of degenerative ocular conditions, such as diabetic retinopathy, retinal vein occlusions, age-related macular degeneration (AMD) including wet-AMD, the leading cause of blindness in the elderly population (556, 557). Here, VEGFA is linked to age-related macular degeneration.
