A Case of Retinal Vasculitis, Uveitis in Myelin Oligodendrocyte Glycoprotein Antibody Associated Optic Neuritis

Abstract

Purpose: To report a case of recurrent optic neuritis with uveitis in a patient with myelin oligodendrocyte glycoprotein (MOG)- associated disease.Case summary: A 16-year-old female presented with left eye hyperemia, glare, and headache. The best corrected visual acuity was 1.2 in both eyes with a left relative afferent pupillary defect. Cells in the anterior chamber, optic disc edema, and subretinal fluid were present, and the distal optic nerve was enhanced on orbital magnetic resonance imaging. Although it improved with steroid treatment, it recurred 3 times in 9 months. At the second recurrence, her visual acuity was reduced to light perception, but she responded well to steroids. During the third recurrence, she visited our hospital for the first time and improved with steroid treatment. However, 18 months after treatment, optic neuritis, uveitis, and macular edema occurred, so oral steroids and eye drops were maintained. Serum anti-MOG antibody came out positive, and at the last visit, visual acuity of 1.2 in the left eye and visual function were maintained well.Conclusions: MOG antibody disease (MOGAD) frequently recurs and invades various structures of the eye and various clinical manifestations have been reported. Therefore, if optic neuritis is accompanied by inflammation of the anterior chamber and retinal vessels, the possibility of MOGAD should be considered.
