Once AION happens, there is no accepted treatment to reverse the damage, but prevention of further damage may be possible. Common sense dictates trying to control the cardiovascular risk factors for many reasons, including protection from this happening to the second eye. Sudden vision loss should lead to an ophthalmological consultation. If AION is suspected, then ideally a neuro-ophthalmology consultation should be obtained. Some rare causes of AION are treatable.
