Ischemic Anterior Optic Neuropathy (AION)
Ischemic AION is a condition where the optic nerve is damaged due to reduced blood flow. This can cause:
- Sudden vision loss
- Blind spots
- Decreased visual acuity
Types
- Arteritic AION: Associated with giant cell arteritis
- Non-arteritic AION: More common, often related to vascular risk factors
Risk Factors
- Age: More common in older adults
- Vascular conditions: Hypertension, diabetes, atherosclerosis
- Giant cell arteritis: Inflammatory condition
Treatment
- Managing underlying conditions: Controlling vascular risk factors
- Corticosteroids: For arteritic AION
- Low vision rehabilitation: Adapting to vision loss
If you suspect AION, seek immediate medical attention from an eye care professional or an optometrist . Prompt treatment can help preserve vision.
