Background: Visual evoked potential (VEP) is a useful noninvasive neurological diagnostic tool affected by certain physical and physiological parameters, age being the major of all. However, only few baseline studies have been conducted in India and none in Gujarat. Materials and Methods: Monocular pattern reversal VEP (PRVEP) was carried out using a standard protocol in medical students of same age group. Latencies of various waveforms were calculated and effects of gender, body mass index (BMI), and head size were studied. Results: Observations revealed normative VEP latencies in line with other studies. Difference observed for only N70 wave, head size were statistical significant and that for BMI, gender, and between eyes were not. Conclusion: Normative VEP data of age, BMI-matched healthy medical students showed no ethnic variation; disproved gender influence on VEP latencies and slight sex difference observed is due to head size. |
