Objective: Patients who had pituitary tumors were investigated using patern visuel evoked, potentials to show the tumors invasion to paracellar region.
Study Design: In 27 patients P-VEP examinations were compared with neuropthalmologic findings and magnetic resonance imaging.
Results: In patients who had pituitary tumor we found that PI00 amplitudes were decreased. In 25 patients P-VEP examinations were pathologic.
Conclusion: The results showed that it was a quick way of searching supracellar invasion and testing of optic pathways.
Keywords: VEP, pituitary tumors
