What Is Ischemic Optic Neuropathy (ION)?

Ischemic Optic Neuropathy (ION) refers to a range of conditions that lead to vision loss due to insufficient blood flow to part of the optic nerve. When blood flow is disrupted, the affected areas cease functioning properly and begin to deteriorate. If the interruption in blood flow is severe or prolonged, it may result in permanent damage to the optic nerve.

The optic disk, located at the back of the eye, is a circular region where blood vessels and the optic nerve connect to the eye. ION occurs around the central part of the disk, known as the optic cup, or further along the optic nerve. ION is relatively rare and typically affects individuals over the age of 50.

Types of Ischemic Optic Neuropathy:

There are two primary forms of ischemic optic neuropathy:

1. Anterior Ischemic Optic Neuropathy (AION)

  This is the most prevalent type of ION, affecting the optic nerve near or beneath the optic disk. AION has two subtypes: 

  - Arteritic Anterior Ischemic Optic Neuropathy (AAION): This involves inflammation of the arteries, often linked with vasculitis (inflammation of blood vessels).

  - Nonarteritic Anterior Ischemic Optic Neuropathy (NAION): This occurs without arterial inflammation, typically due to restricted blood flow to the optic nerve.

2. Posterior Ischemic Optic Neuropathy (PION)

  This type of ION affects the optic nerve further back from the optic disk and also has arteritic and nonarteritic subtypes.

Symptoms and Causes:

Symptoms:

- NAION: Vision loss is usually sudden and painless, often presenting as blurred vision or diminished vision in part of the visual field (commonly the lower half) of one eye. It may also cause reduced colour vision. Vision loss is often first noticed upon waking and can occur gradually over a couple of weeks. NAION typically affects one eye at a time, with approximately 15% of individuals experiencing it in both eyes eventually.

- AAION: Sudden vision loss can range from blurring to complete loss of vision. Symptoms may include headache, swollen arteries in the temples, muscle pain while chewing, general malaise, or unexplained weight loss. Some individuals may experience vision loss without other symptoms of arteritis.

- PION: Both arteritic and nonarteritic forms of PION result in sudden, painless vision loss, which may progress over time.

Causes:

- Nonarteritic Anterior Ischemic Optic Neuropathy (NAION): The exact cause is not well understood but is thought to involve multiple factors that disrupt blood flow to the optic nerve. These factors may include anatomical differences, high blood pressure, Type 2 diabetes, atherosclerosis, sleep apnea, nocturnal hypotension, anemia, smoking, migraines, and certain medications.

- Arteritic Ischemic Optic Neuropathies: Both AAION and APION are caused by arteritis, which leads to widespread inflammation in the circulatory system. Conditions likely to cause this include Giant Cell Arteritis (GCA) and other types of vasculitis.

- Nonarteritic Posterior Ischemic Optic Neuropathy (NPION): This can be caused by conditions affecting eye circulation, sudden blood pressure drops, or factors during surgery.

Risk Factors:

Risk factors for ION include high blood pressure, diabetes, high cholesterol, smoking, sleep apnea, and inflammatory diseases like giant cell arteritis. The condition is more common among individuals over 50, those assigned male at birth (AMAB), and white individuals.
