- Medical examination. A physical examination is often enough to diagnose internuclear ophthalmoplegia.
- Imaging studies. Some patients will need an MRI or a CT scan to locate damage and help diagnose the underlying cause.
- Blood work and cerebrospinal fluid (CSF) studies. These tests may help detect uncommon causes of INO.
Treatment of internuclear ophthalmoplegia will depend upon the underlying condition causing it. Sometimes the condition may be the first sign that a person has multiple sclerosis, which will involve further neurological treatment. Recovery from a stroke also varies greatly. Patients whose internuclear ophthalmoplegia is caused by infection, reaction to medication or trauma usually recover completely. Possible treatment plans may include:
- Botox injections for strabismus (unaligned eyes). When injected into the muscles around the eyes, Botox can help reduce misalignment.
- Corrective lenses, including Fresnel prism lenses
- Surgery to correct strabismus for patients with WEBINO
Patients will continue to follow up with their doctor to monitor symptom progress and to determine if additional treatments are necessary.
