Transsphenoidal surgery for visual loss in patients with pituitary adenomas

This paper presents the results of transsphenoidal surgery in 41 consecutive patients with visual loss from pituitary adenomas. The most common pattern of loss was bitemporal hemianopia. Transsphenoidal decompression resulted in visual improvement in 78% of patients. If patients with optic atrophy and pre-operative complete blindness were excluded, improvement extended to 94% of patients. Because of its efficacy and low morbidity, transsphenoidal resection of pituitary tumours is the procedure of choice for most adenomas with extrasellar extension and visual field loss.
