Optic nerve neuroprotection
WebApr 26, 2024 · The goal of neuroprotection in optic neuropathies is to prevent loss of retinal ganglion cells (RGCs) and spare their function. The ideal time window for initiating neuroprotective treatments should be the preclinical period at which RGCs start losing their functional integrity before dying. Noninvasive electrophysiological tests such as the … WebAug 11, 2009 · Glaucoma is the leading cause of irreversible blindness in the world ().This chronic and progressive optic neuropathy is characterized by loss of axons of the retinal ganglion cells (RGC) that constitute the optic nerve ().Elevated intraocular pressure (IOP) is the primary risk factor for glaucoma, responsible for long-term damage to the optic nerve ().
