Optic glioma

Alternative Names

Glioma - optic; Optic nerve glioma

Treatment

Treatment varies with the size of the tumor and the general health of the person. The goal may be to cure the disorder, relieve symptoms, or improve vision and comfort.

Surgical removal may cure some optic gliomas. Partial removal to reduce the bulk of the tumor is feasible in many cases, which will minimize pressure-induced damage from the tumor.

Radiation therapy may be advised in some cases where the tumor is extensive and surgery is not possible. One newer technique creates a computerized 3D image of the brain and glioma, then irradiates the tumor from many directions. Another promising technique is called proton radiation therapy (PRT). In some cases, radiation therapy may be delayed because of the slow growth that this tumor typically displays.

Corticosteroids may be prescribed to reduce swelling and inflammation during radiation therapy, or if symptoms return.

Outlook (Prognosis)

The outlook is highly variable. Early treatment improves the chance of a good outcome. Many tumors are curable with surgery, while others return.

Normally, the growth of the tumor is very slow, and the condition remains stable for long periods of time. However, in adults and some childhood cases where the optic chiasm is involved, the tumor behaves aggressively.

Possible Complications

• Decreased vision
• Blindness
