Long-term visual outcome after nonradical microsurgery patients with parasellar and cavernous sinus meningiomas.

Abstract

To determine the long-term visual outcome in patients with parasellar and cavernous sinus meningiomas treated with nonradical surgery. Retrospective clinical review of 29 patients with parasellar or cavernous sinus meningiomas and visual sensory or ocular motor dysfunction at presentation, all of whom had at least 10 years of follow-up after initial diagnosis and treatment with nonradical surgery. Nineteen of 29 patients had a unilateral or bilateral optic neuropathy at presentation, and 7 patients developed a unilateral or bilateral optic neuropathy during a mean follow-up period of 13.6 years. However, 27 (93%) of 29 patients retained vision of 20/40 or better in at least one eye, and 14 patients (48%) retained vision of 20/40 or better in both eyes. New ocular motility deficits developed in 3 (10%) of 29 patients during the follow-up period. Radical surgery is not required to achieve long-term useful visual function for patients with parasellar or cavernous sinus meningiomas.
