About this study

Official title: Observation of Anti-vascular Endothelial Growth Factor Therapy in Exudative Age-related Macular Degeneration, Proliferative Diabetic Retinopathy, Macular Edema, and Choroidal Neovascularization.

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.

Questions about this trial

What is this clinical trial studying?

An observational study of Neovascular Age-related Macular Edema and Diabetic Macular Edema, run by Wenbin Wei at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
