Résumé

Acute anterior ischaemic optic neuropathy (AION) is a feared ischaemic complication of giant cell arteritis (GCA). However, distinguishing arteritic AION (A-AION) from its non-arteritic counterpart (NA-AION), which accounts for approximately 90% of cases, can be challenging. Rapid initiation of glucocorticoids is essential to prevent irreversible vision loss in GCA but is unnecessary in NA-AION. This study evaluated the use of orbital MRI in differentiating A-AION from NA-AION.
