Natural History of Nonarteritic Anterior Ischemic Optic Neuropathy

Journal of Neuro-Ophthalmology, 1994
Visual acuity and quantitative perimetry (Octopus Program 32) testing was performed in the acute (< 30 days after onset) and convalescent (> 3 months after onset) phases of disease in 27 patients with untreated NAION. Initial group mean acuity and sensitivity loss were compared to final values using the t test.
