Abstract :
Purpose: Recording of visual evoked potential (VEP) is important in diagnosis of demyelinating diseases and optic nerve atrophy. It is observed that selection of proper stimulation technique is to be taken into consideration in different pathological conditions. Photophobia is among the conditions that selection of proper stimulation technique is helpful in better diagnosis of this type of disease, therefore VEP using two routine stimulation techniques i.e. pattern reversal checker board & flash was tested in photophobia patients to search for possible changes. Migraine disease is among the one that is accompanied by photophobia. Therefore the migraine patients were taken for the purpose of present study. Method: Seventy five migraineurs were selected randomly. VEP was tested using pattern reversal checker board & flash stimulations in total population, VEP, P100 was measured in full population. Result: The result shows increase delay in latency of VEP, P100 in case of flash rather than pattern stimulation. The reason for this delay may be the visual pathway disturbances of these patients which will be discussed in detail in full paper. Conclusion: From the result of present work one can conclude that pattern reversal checker board is a proper stimulation technique for recording VEP in migraineurs.
