Task: Answer Verification
Input (English): Question: Do pre-existing chiasma syndromes entirely remit following transsphenoidal surgery for pituitary adenomas?
Answer: In this unselected patient series, the vision (VA as well as VF) of patients with preoperative CS did not improved postoperatively to the degree of the vision of patients without preoperative CS. Thus, in patients with adenomatous chiasma compression transsphenoidal surgery may be indicated before CS develops.
Output (English): no
