Glaucoma is a major cause of worldwide irreversible blindness. The central role of raised intraocular pressure (IOP) is being questioned as many patients continue to demonstrate a clinically downhill course despite initial control of IOP. The latest concept of recognizing glaucoma as a multifactorial, progressive, neurodegenerative disease of retinal ganglion cells (RGCSs) associated with characteristic axon degeneration in the optic nerve emphasizes that several pressure-independent mechanisms are responsible for the development and progression of glaucomatous optic neuropathy. Neuroprotection as a pharmacological strategy to mitigate retinal ganglion cell death has been a popular current approach. The aim of this review is to evaluate the neuroprotective potential of calcium channel blockers in glaucomatous optic neuropathy.
青光眼是全球不可逆失明的主要原因。随着许多患者尽管眼压最初得到控制但仍继续呈现临床病情恶化的情况,眼压升高的核心作用受到质疑。将青光眼视为一种与视神经中特征性轴突退变相关的视网膜神经节细胞(RGCs)的多因素、进行性神经退行性疾病的最新概念强调,几种与压力无关的机制导致了青光眼性视神经病变的发生和发展。神经保护作为减轻视网膜神经节细胞死亡的一种药理学策略,一直是当前流行的方法。本综述的目的是评估钙通道阻滞剂在青光眼性视神经病变中的神经保护潜力。
