Optic Nerve Sheath Meningioma

What is Optic Nerve Sheath Meningioma?

Optic nerve sheath meningiomas are rare, slow-growing benign tumors on the cells surrounding the optic nerve. The tumors squeeze the optic nerve, interfering with its ability to send vision messages to the brain. Because of their location, the tumors cause vision symptoms and can be difficult to treat.

Causes of Optic Nerve Sheath Meningioma

Most cases of optic nerve sheath meningioma are idiopathic, meaning their cause is unknown. The condition has been associated with exposure to ionizing radiation and neurofibromatosis type 2. The mean age at diagnosis is 40.

Symptoms of Optic Nerve Sheath Meningioma

Patients may often be asymptomatic and may be informed of the diagnosis during a routine exam. In other cases, they may notice dim, blurred vision in one eye. Occasionally, a slight bulge is detected in one eye.

Diagnosis of Optic Nerve Sheath Meningioma

Your doctor will conduct a full vision exam and take your medical history. A diagnosis will typically be confirmed with a CT scan or MRI. A biopsy may also be ordered.

Treatment of Optic Nerve Sheath Meningioma

Watchful waiting may be an option for patients who maintain acceptable vision, but eyesight could continue to decline. If the tumor compresses the optic nerve from one side, it may be possible to surgically remove it, but there may be a negative impact on the patient’s vision. Targeted radiation, such as Gamma Knife therapy, may be recommended in some cases, and outcomes are superior for patients who undergo radiotherapy treatments, according to recent research. If left untreated, the tumors could lead to vision decline and eventually blindness in one eye.
