Neovascular Age-Related Macular Degeneration.
Age-related macular degeneration (AMD) is the leading cause of severe vision loss in individuals over the age of 50 years. Choroidal neovascularization (CNV) is the hallmark of 'wet' or 'exudative' AMD, and is responsible for approximately 90% of cases of severe vision loss due to AMD. Vascular endothelial growth factor (VEGF) is a key component in the development and progression of wet AMD. Since the approval of ranibizumab in 2006, VEGF inhibitors have rapidly altered the treatment and standard of care for wet AMD. Ranibizumab, bevacizumab, and aflibercept are now the most widely used anti-VEGF agents for the treatment of wet AMD. This chapter discusses the pharmacologic properties, pharmacokinetics, safety, and efficacy of these medications, as well as revisits landmark clinical trials that establish these drugs as gold standards in care. While these medications have greatly and positively altered the way we treat AMD, there are still many economic and therapeutic limitations with our current therapy regimens. There continue to be advancements and innovations in exploring alternative and new treatment modalities, as well as combining existing treatment options to improve efficacy, and reduce cost and patient burden.
