Vision salvage after resection of a giant meningioma in a patient with a loss in light perception.

Abstract

Clinical approaches to the surgical management of optic chiasm compression stress quick action, as several case series have demonstrated minimal vision restoration following aggressive decompression in patients presenting more than 3 days after the onset of blindness. The authors here report the case of a 48-year-old woman who presented with near-complete binocular vision loss but regained visual function following surgical removal of a giant planum-tuberculum meningioma, which was performed 8 days after a documented loss in light perception. The interval between the patient's vision loss and successful vision-restoring decompressive surgery is the longest recorded to date in the literature. This case shows the importance of aggressive decompression of mass lesions despite extended intervals of optic nerve dysfunction.
