The patient was a 31-year-old female with a history of vision loss since 11 days ago (left eye). At presentation, best-corrected Snellen visual acuity was 20/140 in the Snellen chart. We decided to treat her with short time corticosteroid therapy (0.75 mg/kg/day prednisolone which was tapered in 3 weeks) for any possible rapid recovery of vision. The visual acuity of the involved eye was improved to 20/25 and 20/20, one week and three weeks after starting treatment respectively. Thus, it seems that short-term oral steroids might be an alternative method of management for patients with MEWDS. https://ijaai.tums.ac.ir/index.php/ijaai/article/view/2508
