Abstract

Background: Visual evoked potential (VEP) is a valuable diagnostic test in symptomatic and subclinical cases of MULTIPLE SCLEROSIS. The aim of this study was to evaluate the rate and abnormal patterns of VEP in patients with definite diagnosis of MULTIPLE SCLEROSIS. Materials and Methods: Two-hundred definite cases of MULTIPLE SCLEROSIS including 144 women and 56 men (15-52 years old) were enrolled in the study and underwent VEP examination. Latencies and amplitudes of potentials were registered. The control group consisted of 25 healthy men and 25 healthy women with an age range of 16 to 48 years. Results: Among the 200 definite clinically proven cases of MULTIPLE SCLEROSIS, 147 cases (73.5%) had an abnormal VEP and 121 cases (60.5%) had visual problems. Seventy-nine cases (39.5%) had no visual problems. In the first group, 119 cases (98.3%) and in the second group, 28 cases (35.4%) had an abnormal VEP, respectively. Conclusion: In this study, the most valuable diagnostic findings were prolonged P1 latency and its interocular difference. Amplitude changes alone had less diagnostic yield.
