Severe Chorioretinal Folds after Optical Neuritis

A 40-year-old man had an isolated episode of optic neuritis of the right eye. Fundoscopy revealed exuberant optic disc swelling with chorioretinal folds (A). Magnetic resonance imaging revealed discrete optic nerve swelling and contrast enhancement. No etiologic cause of his optic neuritis was identified. He was treated with systemic corticosteroids and had complete recovery of visual acuity, color vision, and visual field. However, he experiences severe metamorphopsias due to persistent chorioretinal folds, visible in fundus fluorescein angiography and OCT (B).
