  • Title: [Electroretinography by reversal pattern in patients with migraine without aura].
    Author: Moreira Filho PF, Dantas AM.
    Journal: Arq Neuropsiquiatr; 1995 Sep; 53(3-B):598-603. PubMed ID: 8585816.
    Abstract:
    Seventeen patients with migraine without aura were investigated: the age was between 16 and 39 years, 6 were men and 11 women. The diagnosis of migraine was made according to the classification proposed by the International Headache Society. The method of electroretinogram was performed with pattern reversal (PERG), with monocular stimulation. The stimulation was performed with pattern reversal with 4 x 4 cm black and white squared screen placed one meter from nasion at stimulus frequency 1/s; 512 individual trials were analysed. The PERG did not show a significant increase in the value of the P50 and N95 latency in our cases. Specifically in one of our cases no wave was detected in the left eye.
