[Visual outcome in pituitary adenoma and supra sellar meningioma (author's transl)].

To determine factors influencing ultimate visual outcome following surgical decompression of pituitary adenoma and suprasellar meningioma, the authors analyse the post-operative visual function of 19 patients with pituitary tumors and of 11 with meningiomas encroaching upon the anterior visual pathways. Their data indicate that : visual impairment tended to be worse and of larger duration with meningiomas than with adenoma. No pre-operative data were of prognostic value for visual outcome with meningioma; for adenoma, younger age, a short duration of symptoms and transsphenoidal approach all positively influenced ultimate visual recovery. Even with minimal visual deficits, eyes tended not to recover completely.
