We describe an exceptional instance of multiple sclerosis manifesting in a unilateral, superior visual field deficit accompanied by painful eye movements. A ۱۶-year-old girl with no prior health issues presented with symptoms of blurred vision, ocular pain in eye movement, and a throbbing headache in her right eye. She experienced right-sided numbness for two weeks, which later affected her left limbs. Effective management of multiple sclerosis necessitates familiarity with its uncommon presentations due to the significance of early diagnosis and treatment. Unilateral superior altitudinal visual field defect, orbital pain upon eye movement, and left hemi-paresthesia may be an uncommon presenting symptom in MS patients. After completing treatment with methylprednisolone, visual acuity can improve completely.
