Background and objectives: Multiple sclerosis, a neurological disease with or without optic neuritis may cause abnormal visual evoked potential finding. This study aimed to evaluate role of visual evoked potential in diagnosing multiple sclerosis.
Methods: In a comparative cross-sectional study, conducted between 1stJune to 15thAugust 2023 in Shahid Aso teaching hospital, Sulaimani, Iraq. Visual evoked potential and brain magnetic resonance imaging performed for twenty patients which clinically diagnosed or suspected as multiple sclerosis. The data was analyzed by (Statistical Package for the Social Science).
Results: In this study eleven male and nine female patients in age range of 18 to 54 years participated, no significant relationship found between visual evoked potential finding with age and gender. Thirteen patients had prolonged visual evoked potential findings. Abnormal brain magnetic resonance imaging findings found in 50% of patients, from which 80% showed prolonged visual evoked potential findings. Fifty percent of patients with normal brain magnetic resonance imaging had prolonged p100 latency. There is a significant relationship at 0.01level between prolonged p100 latency and presence of finding on brain MRI.
Conclusion: Visual evoked potential, as a paraclinical biomarker helps diagnosing multiple sclerosis in patients with or without optic neuritis. In this study, abnormal brain magnetic resonance imaging was positively related with prolonging P100 latency on visual evoked potential in multiple sclerosis patients.
