Optic nerve decompression surgery plays adjuvant role to radiation

Optic nerve decompression may have an important adjuvant role to radiation for treating patients with optic nerve sheath meningioma, a recent study suggests.
Roger E. Turbin, MD, FACS, and colleagues performed decompression surgery on two patients with unilateral optic nerve sheath meningioma. Both patients had experienced progressive visual loss and disc edema.
The first patient received fractionated stereotactic radiotherapy before undergoing decompression. The second patient had previously undergone decompression and subsequently received radiotherapy, according to the study.
Postoperatively, visual acuity improved from 20/200 to 20/25 in the first patient and improved from no light perception to 20/200 in the second patient. The improvement in vision coincided with resolution of disc edema in both patients, according to the study.
The study was published in the July/August issue of Ophthalmic Plastic and Reconstructive Surgery.
