Compressive Optic Neuropathy Treatment & Management

Medical Care
- Corticosteroids are useful in compressive optic neuropathy caused by inflammation and thyroid ophthalmopathy.
- Symptoms from other causes of compressive optic neuropathy also may improve with use of corticosteroids.
- Radiation therapy often is appropriate for malignant lesions and may benefit intracanalicular and possibly intraorbital meningiomas.
- A favorable response to treatment with corticosteroids should not be considered as confirmation of a diagnosis until good quality MRIs and CT scans are obtained.
- A practical approach for those cases in which the MRI and/or CT scan strongly indicates a meningioma (both intraorbital and intracanalicular) is to monitor the patient with serial visual acuity measurements and field testing. If visual loss progresses, consider treatment with radiation, and, if growth continues, then also consider surgery.
Surgical Care
- Consider surgical excision or decompression as a treatment option when orbital tumors compress the optic nerve. Apical optic nerve tumors (eg, cavernous hemangioma) may require an orbitocranial approach.[7]
- The definitive procedure for optic neuropathy of Graves disease is orbital decompression. Although advocates of steroids and radiation exist, decompression is the best and most assured way of reversing the compression aspect of this disorder.
- Optic canal decompression for tumors in the intracanalicular area is extremely risky and not uncommonly results in the loss of any remaining vision, unless the tumor has a large exophytic component.
- If the tumor is intimately involved with the optic nerve, as often is the case with nerve sheath meningiomas, surgical removal often results in further loss of vision. This is thought to be due to a compromise of the shared blood supply.
Consultations
Patients with compressive optic neuropathy should be managed in consultation with a neuro-ophthalmologist or an orbital surgeon whenever possible.
Activity
Prescribe polycarbonate safety glasses to patients with compressive optic neuropathy to protect the vision in the unaffected eye.
