Ophthalmology Volume 115, Issue 2, February 2008, Pages 298-305.

The purpose of this study was:

" To investigate systematically the natural history of visual outcome in nonarteritic anterior ischemic optic neuropathy (NAION)."

The conclusion was:

"About half of the eyes with NAION presented with almost normal visual acuity (20/15 to 20/30) at the initial visit. Thus, the presence of normal visual acuity does not rule out NAION. Visual acuity and visual fields showed improvement or further deterioration mainly up to 6 months, with no significant change after that."
