Anti-vascular endothelial growth factor therapy is the major intervention for treating ischemic retina diseases. According to FDA and China Food and Drug Administration, Ranibizumab, Aflibercept, and Conbercept are major types of anti-vascular endothelial growth factor therapy drugs. In the current study, the primary aim is to observe the visual acuity, anatomy effect of anti-vascular endothelial growth factor therapy in the real-world setting.

Anti-vascular endothelial growth factor therapy is the major intervention for treating ischemic retina diseases, including neovascular age-related macular edema, diabetic macula edema/non-proliferative diabetic retinopathy / proliferative diabetic retinopathy, retinal vein occlusions related macular edema, and choroidal neovascularization secondary to multiple retinal diseases. According to FDA and China Food and Drug Administration, Ranibizumab, Aflibercept, and Conbercept are major types of anti-VEGF drugs. In the current study, the primary aim is to aim to observe the visual acuity, anatomy effect of anti-vascular endothelial growth factor therapy in the real-world setting.
