A 21-year-old girl presented with acute painless vision loss in her right eye. There was no remarkable ocular history and she had a history of anorexia nervosa. At presentation best-corrected visual acuities were counting fingers from 2 meters and 20/20, in the right and left eyes, respectively. Slit lamp examination result was normal. Fundus examination revealed multiple cotton wool spots and intraretinal hemorrhages surrounding the optic disc and macula in the right eye. Fluorescein angiography showed capillary filling defect and leakage from optic disc in the late phase of the angiogram. One week later best-corrected visual acuities remained the same in both eyes with similar fundus appearance. One month after initial presentation visual acuity was 20/20 in both eyes with no abnormality in fundus appearance.
