Loss and recovery of vision with suprasellar meningiomas.
Central visual acuity losses were documented in a group of 23 patients with surgically and histologically verified suprasellar meningiomas. The pattern demonstrated was that of acute, gradual or fluctuating loss in one eye, followed by later loss of central acuity in the other eye. Both optic nerves and chiasm were invariably involved either by stretching or compression. Neither preoperative field abnormalities nor central acuity deficits could be correlated with the anatomical location of the tumor, nor could postoperative changes in vision be correlated with tumor size. Lengthy duration of acuity loss and severe visual deficit did not preclude postoperative recovery of vision. Improvement in sight most frequently occurred within the first several weeks after operation, and further return of vision was not noted after 1 year.
