The VEP in evaluation of pituitary tumors

Electromyogr Clin Neurophysiol. 1991 Apr;31(3):163-5.

Abstract

12 patients with pituitary tumors were studied with VEP, to demonstrate involvement of the optic chiasma. In 3 patients VEP was recorded pre- and post-surgery to evaluate a modification in the shape and latencies of the potentials. 2 patients were studied only pre-surgery, the other 7 post-surgery. The utility of this test is discussed.
