Pattern shift visual evoked potentials in Charcot-Marie-Tooth disease, HMSN type I.
Pattern shift visual evoked potentials were investigated in 9 subjects with Charcot-Marie-Tooth disease, who were classified as HMSN I on clinical, genetic and electromyographic criteria. The latency of the second positive peak was increased in 7 eyes of 5 subjects. These results suggest that patients with HMSN I the optic nerves may be affected more frequently than suspected on clinical examinations.
