Anterior Ischemic Optic Neuropathy is also known as (AION). This is considered the first form of a stroke of the eye or optic nerve. is a visually devastating disease that occurs in the middle aged and the elderly. It begins suddenly with little warning in one eye, but frequently progresses to the other eye over time
The second form is known as Non-Arteritic" Anterior Ischemic Optic Neuropathy or NAAION. This is the most common form of AION and generally has a better visual outcome than the arteritic form.
The most common diseases which can put a patient at higher risk for NAAION are Diabetes mellitus, shingles, anemia, rheumatoid arthritis and so on.
the mechanisim of the condition, of either type is due to ischemia or poor circulation to the blood vessels of the optic nerve. Without nutrients and oxygen, a portion of the nerve tissue will be lost.
