Clinical manifestation of a 40-year-old woman without any specific laboratory findings. Fundus photographs showed optic disc edema of only the left eye (A, B), optic disc swelling was observed, although there was no macular abnormality seen in optical coherent tomography (E) at the initial visit. Fluorescein angiography (C, D) showed that the inflammatory focus was around the optic disc of the left eye. Three weeks after the initial visit, optic disc swelling was noticed in both eyes (F, G), and subretinal fluid and hard exudates were observed in optical coherent tomography of her left eye (H). Three months later, without any specific treatment, these abnormalities returned to almost-normal (I, J, K)
