Hyperhomocysteinaemia in young patients with non-arteritic anterior ischaemic optic neuropathy

Abstract

Elevated plasma homocysteine may be associated with NAION. An evaluation for hyperhomocysteinaemia should be considered in patients with NAION who do not have the typical risk factor such as older age, diabetes, hypertension, or tobacco use. It should also be considered in young patients with bilateral or recurrent attacks of NAION.
