Treatment of NAION

Topics about treatment of NAION are very controversy.
100 articles about treatment of NAION were searched in Pubmed so far.

Prof Hayreh, one of the leading professors in the field of ischemic optic neuropathy, suggested that high-dose systemic corticosteroid therapy improved visual field defect. 
However, several ophthalmologists do not agree with prof. Hayreh.

Recently, Intravitreal ranibizumab injection is being considered to treat NAION.
Bajin et al. reported that Intravitreal ranibizumab injection may be a treatment option in eyes with non-arteritic anterior ischemic optic neuropathy and a short disease history.

I think that the results of systemic corticosteroid or intravitreal ranibizumab injection may be affected by severity of disc swelling or optic disc vascular insufficiency. Thus, we need more well designed randomized control study.

Some reports presented the effectiveness of Aspirin to prevent recurrence of NAION.
