Ischemic Optic Neuropathy

Arteritic Ischemic Optic Neuropathy

Arteritic AION is a dangerous condition caused by inflammation of arteries supplying blood to the optic nerve. The inflammation is due to a condition known as giant cell arteritis (GCA) or temporal arteritis, which causes inflammation of medium- and large-sized arteries.
It is almost always in older than 50 years, with an exponential increase with advanced age (90% of patients are 60 y). Rare cases of AION occur before 40 years.
