Age-related macular degeneration (AMD) is a condition that may cause blindness. The prevalence of the disease in the Western world is estimated at 1-2% of the population. Over the past decade, treatment of neovascular AMD has been shifting from destruction of newly formed blood vessels towards inhibitors that silence the vascular endothelial growth factor (VEGF) pathway. Such agents are often first-in-class biopharmaceuticals that benefit from the fact that they can be locally administered in an immune-privileged environment with slow clearance. These new VEGF pathway inhibitors have improved therapeutic effects over conventional treatment and have promoted the identification of novel targets for inhibition of AMD angiogenesis. This review describes the rationale behind the shift from conventional to current treatment options and discusses investigational, most notably biopharmaceutical, drugs that are in clinical trials. It also provides possible points for improvement of these treatments, specifically regarding their delivery.

:与年龄有关的黄斑变性(AMD)是一种可能导致失明的疾病。据估计,该疾病在西方世界的患病率为人口的1-2%。在过去的十年中,新血管AMD的治疗已从破坏新形成的血管转向抑制血管内皮生长因子(VEGF)通路的抑制剂。此类试剂通常是一流的生物药品,这得益于它们可以在免疫特权较低的环境中以缓慢清除的方式局部给药的事实。这些新的VEGF途径抑制剂与常规治疗相比具有改善的治疗效果,并促进了抑制AMD血管生成的新靶标的鉴定。这篇综述描述了从常规治疗方案向当前治疗方案转变的基本原理,并讨论了临床试验中的研究性药物,尤其是生物制药。它还为改进这些治疗方法提供了可能的要点,特别是在治疗方面。
