As a routine part of the evaluation of patients with pituitary tumour, pattern reversal visual evoked potentials (PRVEP) were recorded in 100 patients with computerized tomographically documented pituitary tumour. VEP tests were correlated with examinations of visual scuity. visual field and computerized tomographic scan. Our study confirme that suprasellar extension of pituitary adenomas caused VEP changes such as latency delay and decrease in amplitude.
