Etiology: In most cases it is thought that vascular disease plays the primary role. The cystic spaces are created by the loss of neuronal tissue that is more sensitive to ischemic injury than the surround supportive connective tissue. [missionforvisionusa.org]

Etiology The vast majority of cases of NAION are idiopathic but some specific etiologies have been reported to be associated with NAION although in all of the cases, no causal relationship has been definitively established. [eyewiki.aao.org]

EPIDEMIOLOGY AND PATHOGENESIS Nonarteritic anterior ischemic optic neuropathy (NAION) is the most common acute optic neuropathy in patients over 50 years of age, with an estimated annual incidence in the United States of 2.3–10.2 per 100,000 population [medtextfree.wordpress.com]

Abstract Objective: To investigate the pathophysiologic mechanism of optic nerve infarction in giant-cell arteritis (GCA). [neurology.org]

Pathophysiology The pathophysiology of NAION is controversial and no one mechanism had been definitively demonstrated. [eyewiki.aao.org]

No clinically effective treatments exist, largely because little is known about its pathophysiology, and there are few histopathological studies of the acute condition. [10] An exhaustive review article published in March 2009 described the latest information [en.wikipedia.org]

That appears to be the pathophysiology of AION." A "disc at risk." A small, crowded optic nerve head is a risk factor for AION; if axons swell, they may compress neighboring axons, triggering a cascade. All images courtesy of Jacqueline M.S. [reviewofophthalmology.com]
