Background:
Pituitary tumors are adenomas of a region of the sella turcica which can produce compression of the anterior visual pathway.
Patients And 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.
