title: [Neurophysiologic follow-up in patients with hypophyseal adenoma operations].
abstract: BACKGROUND
  Pituitary tumors are adenomas of a region of the sella turcica which can produce compression of the anterior visual pathway.
  
  
  METHODS
  Besides clinical signs of visual improvement such as enhanced visual acuity and visual field, the use of electroophthalmological methods can help monitor patients after neurosurgery.
  
  
  RESULTS
  The N75 P100 amplitude of the p-VEP has proven to be the most sensitive marker for measuring-improvements after surgery. This amplitude significantly increased, whereas latency time, visual acuity and visual field showed no statistically significant changes after surgery.
  
  
  CONCLUSIONS
  The p-VEP is an important tool in treating patients with compression of the visual pathway.
