What is NAION: Epidemiology and Pathogenesis about?
Nonarteritic anterior ischemic optic neuropathy (NAION) is the most prevalent form of ischemic optic neuropathy, primarily affecting older adults with a mean age of 60 years. It is characterized by acute, painless visual loss and is associated with various risk factors including age, diabetes, and hypertension. The exact pathogenesis remains unclear, but it is believed to involve ischemia to the optic nerve head, potentially exacerbated by structural abnormalities and atherosclerotic risk factors.
