Abstract

Background and Aim: Visual evoked potential (VEP) is a useful noninvasive neurodiagnostic tool which permits assessment of functional integrity of visual pathways. It is affected by certain physical and physiological parameters. To date, only few baseline studies have been carried out in India assessing the effect of gender on VEP. Therefore, the present study was conducted to evaluate the effect of gender on VEP. Materials and Methods: 30 healthy subjects of either sex within the age group 18-40yrs were recruited and divided into male and female group with 15 subjects in each group. Monocular pattern reversal visual evoked potentials (PRVEP) were recorded using standard protocol. Latencies and amplitude of various waveforms were calculated and studied. Results: Our study revealed longer latencies of all the waves in male group than the female group in line with other such studies; however the difference was not statistically significant (p value > 0.05). Statistically insignificant difference in amplitude of P100-N75 and inter-ocular difference in P100 latency was also observed. Conclusion: The present study disproved the influence of gender on VEP. However, more studies with bigger sample size are advocated.
