Angiogenesis is a multi-stage process of new vessel development which involves migration, proliferation and differentiation endothelial cells. Pathological angiogenesis plays crucial role in the pathomechanism various ischemic, malignant inflammatory disorders. Among eye diseases, macular degeneration (AMD) proliferative diabetic retinopathy are major public health issue as most common causes blindness. Since these conditions, there has been an increased interest evaluating anti-angiogenic...
