- Medical history, symptom review and physical examination. Diagnosis begins with discussion of symptoms and medical history, along with an examination by an ophthalmologist.
- Blood tests. Different types of ION result in abnormal levels of certain proteins (such as C-reactive protein) and inflammation in the body. Special blood tests measure these amounts to help determine the exact type of ION present.
- Biopsy. A small part of a blood vessel in the head is removed to determine if giant cell arteritis is present.
- Additional Tests. If other symptoms are present and indicate underlying health conditions, testing may be performed to determine what those conditions may be.
Medication. If ION affects a single eye, a systemic corticosteroid may prevent it from impacting the other eye. This is used when the condition is caused by temporal arteritis.
Health Management. Underlying health conditions that increase your risk for ION, such as diabetes and high blood pressure, should be managed. This may require medication or lifestyle changes.
Vision Assistance. Unfortunately, vision lost from ION cannot be restored. However, special tools and techniques enable you to make the most of your diminished vision.
- Regular medical checkups help monitor the progress of ION. Should symptoms worsen, a change in medication or lifestyle or additional assistive devices may help maintain as much vision as possible.
