Abstract (Original Language):
Introduction: A visual evoked potential is electrical potential difference recorded from the scalp inresponse to visual stimuli. The VEP
tests the function of the visual pathway from the retina to the occipital cortex. It is a simple, non- invasive electro physiological test. The
present study was planned to evaluate the changes in pattern of visual evoked potential (VEP) in different phases of menstrual cycle .
Materials and methods: The study included 50 young healthy female medical students of age group 18 to 25 years having regular
menstrual cycles. The left and right eye tested separately in all subjects by giving mono ocularstimulation. The important parameters of
VEP latency and amplitude of P 100 was measured. The statistical analysis was done by Student unpaired’t’ test.
Results: There was statistically significant prolongation of latency P 100 wave and decrease of amplitude of VEP in follicular phase as
compare to luteal phase.
