Abstract

Pattern visual evoked potentials (VEPs) and electroretinograms (ERGs) were recorded in 20 patients with myotonic dystrophy. Thirteen out of 20 cases presented both VEP and ERG abrnomalities, 3 only ERG alterations, 2 only abnormal VEPs. A significant inverse correlation between P100 latencies and b1 wave amplitude was observed, while N1-P100 and b1 wave amplitude exhibited a parallel change. These data suggest that retinal abnormalities may have a role in inducing subclinical visual pathway alterations in myotonic dystrophy.
