Background: The visual evoked potentials refer to the change in brain activity when we apply intermittent visual stimulus to visual system.Visual evoked potential provide a quantitative measures of the functional integrity of the visual pathway.The present study was done to investigate the relation between patternreversal visual evoked potential parametersandanthropometric parameters (Height, weight, BMI & BSA) in healthy subjects.Only few baseline studies have beenconducted in India

Material and Method:–Monocular patternreversal visual evoked potential was recorded using a standard protocol in randomly selected 120 healthy volunteers of Haryana population within the age group of 18 to 25 year. Latencies of various waveforms were calculated and effect of various anthropometric parameters including age, height, weight, BMI, BSA and Head circumference were studied.

Results:– The present study showed the difference in latency and amplitude of VEP between male and female indicatinggender is an important variable affecting the VEP. Significant positive correlation found between BMI, weight, height and P100. No relation observed between BSA and VEP.

Conclusion:–Significant positive correlation found between BMI,Weight,height and P100
