Anterior ischemic optic neuropathy (AION) is a medical condition involving loss of vision caused by damage to the anterior portion of the optic nerve as a result of insufficient blood supply (ischemia). This form of ischemic optic neuropathy is generally categorized as two types: arteritic AION (or AAION), in which the loss of vision is the result of an inflammatory disease of arteries in the head called temporal arteritis, and non-arteritic AION (abbreviated as NAION, NAAION,[1] or sometimes simply as AION), which is due to non-inflammatory disease of small blood vessels.[2] It is in contrast to posterior ischemic optic neuropathy, which affects the retrobulbar portion of the optic nerve.
