Beneficial Effects on Visual Disturbances as a Result of Transsphenoidal Surgery

Abstract

Effects of transsphenoidal surgery on decompression of the optic nerve and chiasm were evaluated in sixteen cases of pituitary adenomas with visual disturbances.
After transsphenoidal surgery, visual acuity was normalized in 34.6%, improved in 53.8%, unchanged in 7.7% and worse in 3.8%. Complete recovery of the visual field was achieved in 26.9%, widening of peripheral isoptors occurred in 46.2%, and it remained unchanged in 23.1% and became worse in 3.8%.
Transsphenoidal surgery for pituitary adenomas is effective and has relatively few complications.
