Abnormal visual evoked potentials in myotonic dystrophy.
Pattern-shift visual evoked potentials (VEPs) were recorded in 17 patients with myotonic dystrophy. Abnormalities of latency or amplitude were found in 10 patients (59%) with no obvious retinal or other significant ocular abnormality. All patients had a visual acuity of 20/30 or better. Since most patients had bilateral VEP abnormalities, localization of the disturbance was not certain.
