title: Electroretinography in the evaluation of childhood myotonic dystrophy.
abstract: Electroretinography (ERG) may provide laboratory support for the diagnosis of childhood myotonic dystrophy. The sensitivity of ERG may exceed that of electromyography for early detection of the disease. The electroretinographic abnormalities are not specific for myotonic dystrophy.
